Heat Output
The nominal heat output of the output device itself is 22,250-26,250 BTU/hr.
For heat output of the UDRC, please see the
UDRC Site Preparation and
Requirements
document (725-00089A).
Power Line Voltage/Frequency
Line voltage at the customer site must remain 6%/–10% of the
Lotem 400 / Lotem 400 Quantum Family output devices rated voltage of 200 V–
240 V for
110 V countries, or between 180V and 254 V for 220 V countries.
The frequency is 50/60 Hz
±
1.5%.
The electrician at the customer site should install the correct outlet to provide
power to the device. The device must be powered from a different line than the
workstation. Tolerances for the specified input voltages require balanced power
inputs (L1–G=L2–G, or L1G=L1–N).
Power connectors must be of the locking type in North America and Industrial
type B in Europe, due to the high leakage current of the equipment. Frequency is
50/60Hz ±1.5%. See “
Erratic performance of platesetter - Uninterupptable power
supply (UPS)/power conditioner requirement
” document on eCentral.
Power Line Disturbances
The reliable operation of computer systems depends on the availability of relatively
noise-free AC power. Lightning, line faults, or power switching commonly found
in machinery, office equipment, and factory environments, can generate line
transients that far exceed the peak value of the applied voltage. If not attenuated,
these microsecond pulses can disrupt system operation. The power line to the
machine should be run away from electrically noisy power cables. If power line
disturbances are affecting the operation of the machine, the use of a power
stabilizer is highly recommended.
Dips in power should not exceed 30% of nominal voltage, having maximal
duration of 10 ms. Fast transient disturbances on the power line should not exceed
1.0 kV.
Grounding
At 60 Hz sites, 208 Vac (between 2 phases of 120 Vac each).
At 50 Hz sites, 380 Vac grounds.
Grounding requirements for platesetter – and all equipment communicating with
it – should be observed to ensure trouble-free operation.
