Electrical Requirements

General Considerations

The total power consumed by your system will be determined by the system configuration selected. Remember to allow sufficient margin for system expansion when calculating the required electrical capacity.

Electrical Supplies

Each separate piece of equipment will be individually powered from source, allowing maximum permutation of layout, and reduced dependency during operation. Provision of sufficient power sockets must therefore be taken into consideration.

All equipment will operate from standard mains supply sockets. The Imagesetter is switch-selectable to comply with a wide range of voltage applications.

Supply voltage variations of up to ±10% on all selectable voltages. Supply frequency variations of ±2 Hz are similarly acceptable.

The main circuit breaker should be a shunt trip breaker, which trips on loss of voltage. A single phase isolated outlet is required for the Imagesetter.

Note the following guidelines:

The input power cable (from the building input feeder/main power entrance to the system branch circuit power panel) should be a dedicated line, 5-wire protected cable, not longer than 30 m (100 ft).

Output circuit breakers should be used for every branch circuit (outlet). Each circuit breaker should be labeled, identifying its load relationship, and correspondence to outlet.

Additional isolated single phase outlets are required for service purposes.

Special codes and regulations may exist covering the installation of electrical facilities in general, and in computer sites in particular. Ensure that site construction complies with these local codes before the system is delivered.

Power Line Disturbances

The reliable operation of computer systems depends on the availability of relatively noise-free AC power.

Lighting, line faults, or the power switching, commonly found in machinery or equipment in office or factory environments, can generate line transients which far exceed the peak value of the applied voltage. If not attenuated, these micro-second pulses can disrupt system operation.

NOTE THE FOLLOWING GUIDELINES

• Limited power supply attenuation has been incorporated into your equipment to minimize the possible effects of disruptive factors (such as transient and instantaneous power interruptions).
• Since these conditions are unique to your particular site, we recommend additional protection, including provision of a mains input circuit breaker with shunt trip, and an isolation transformer with common mode noise attenuation of greater than 120 dB.
• It is recommended that the power conditioner isolation transformer used should be one which includes a power distribution system (output circuit breakers and receptacles). When installed in the system room, the conditioner/transformer will make system installation easier and reduce installation time and cost.
• All other potential noise-generating equipment (e.g., fans, fluorescent lighting and air-conditioning system) must be separated from the power source used for the system.

Grounding

The power ground system for 50 Hz sites should include the 220 VAC and 380 VAC grounds, tied back to the main power ground point of the building by means of a 40 mm solid copper wire (7 mm in diameter).

At 60 Hz sites, 220 VAC, 110 VAC, and 208 VAC grounds tied by AWG #1 solid copper wire are required.

Grounding requirements for the Imagesetter—and all equipment communicating with it—should be observed to ensure trouble-free operation.

Grounding requires the following:

• Grounding wires must be insulated and at least equal in size to the phase conductors.
• Ground impedance less than 2 ohms.
• A single point and dedicated ground.
• The power stabilizer equipment should be supplied by three (3) uninterrupted phase wires, and one uninterrupted copper ground wire, from the main building entry service panel. They should run in the same conduit and be at least equal in size to the phase wires.
• Verify that neutral and ground are bonded together in the main building entry service panel, and that there is a good earth ground at this point of not more than 2 Ohms impedance.
• Each system load (Imagesetter, Host, etc.) will be fed through an isolated ground outlet and have a separate ground, as well as neutral and phase line of equal size wire. Chained neutrals or grounds are not permissible.
• All ground wires from isolated ground outlets will be kept isolated from building ground and terminated only at the ground bus of the power stabilizer.
• Other equipment, not on the power stabilizer but communicating with the Imagesetter must have a reference ground wire installed between the power stabilizer ground bus and that piece of equipment.

These instructions do not replace any enforced government or local standards. The installer should check the applicable electrical code and assure full compliance.

Cables

If cables must be routed through a wall, the holes in the wall should be as follows:

• Round holes should be 10 cm (4 in) in diameter
• Square holes should be 8.9 cm (3.5 in) in diameter

No electrical wiring (stabilized or unstabilized) may run in the data cable conduit.

Space/Floor Requirements

Floor Space

Depending on the model, the Imagesetter requires between 5.7 and 6.32 cubic meters of space. This measurement reflects the area required around the Imagesetter, to allow for unimpeded work and considerations such as heat dissipation. The following figure depicts the minimum floor dimensions required for proper operation of the Imagesetter. [RDR2]

Imagesetter Space Requirements

NOTE: This diagram does not depict use of an on-line processor. Refer to On-Line Processor Requirements, for details.

Imagesetter Weight

The Imagesetter weighs between 180 and 230 kilograms and rests on four symmetrically-placed cushioned legs. Most standard industrial floors are strong enough to support the Imagesetter, though actual room dimensions and additional equipment at the site should be considered.

Film Processor & Safety Light

Safety Light Bright Cyan

The standard film will be orthochromatic (red sensitive), requiring a bright cyan safety light. (For more details, refer to the film manufacturer’s recommendations.)

Although the film must be loaded into its cassette in a suitable darkroom, following this initial step, routine film handling can be under normal daylight conditions. Direct sunlight should always be avoided.

Recommended Inline Processor Manufacturers

The following manufacturers have designed ILP models which are compatible with the Imagesetter:

• Glunz & Jensen
• Lüth
• Echo Graphic

Environmental Requirements

Cleanliness

Cleanliness of standard laser operating environment, i.e., up to 0.168 milligram/M (Class 4, B.S. 5295) as follows:

• Up to 200,000 particles/M³ when greater than 5 microns
• Up to 40,000 particles/M³ when greater than 10 microns
• Up to 4,000 particles/M³ when greater than 25 microns

Filters in the air conditioning system will be able to block 60% of all 10 micron dust particles.

Static Electricity

Use of floor carpeting is not recommended in the Imagesetter area. If carpets will be used, only anti-static carpets will be installed at the site. Their size should be at least 2.5 m (8 ft) in all directions of Operator's access.

Air Conditioning

Sufficient air-conditioning should be present to provide heat dissipation for the Imagesetter (1500 BTU per hour) plus all additional equipment residing in the System room plus a minimum 25% safety margin.

Example: (all in BTU/hour)

Imagesetter:	1500
Host:	2500
Light Table:	+ 3500
Other Misc:	1500
Safety Margin: (25% of above)	+ 2250
Total Heat:	11250

• The Imagesetter requires a constant air temperature of 24°C ± 2°C and relative air humidity of 55% ± 5%.
• The maximum temperature variation is 5°C per hour.
• The minimum allowed temperature is 10°C.

Note the following guidelines:

• It is recommended that the air flow in the System room be maintained above normal air pressure, in order to prevent dust from entering the room.
• The System room should ideally contain both a thermometer and hygrometer, permanently mounted in a central location.

Film Handling

The standard film will be orthochromatic (red sensitive), requiring a bright cyan safety light. (For more details, refer to the film manufacturer's recommendations.)

Although the film must be loaded into its cassette in a suitable darkroom, following this initial step, routine film handling can be performed under normal daylight conditions. Direct sunlight should always be avoided.
