SAFETY SUMMARY
This power source contains high voltage and current circuits, which are potentially lethal.
Because of its size and weight, mechanical stability must be ensured. The following safety
guidelines must be followed when operating or servicing this equipment. These guidelines
are not a substitute for vigilance and common sense. California Instruments assumes no
liability for the customer’s failure to comply with these requirements. If the power source is
used in a manner not specified by California Instruments, the protection provided by the
equipment may be impaired.
BEFORE APPLYING POWER
1.
Verify the correct three phase input voltage is applied to the unit. Input ratings are shown on the
model and serial number tag located at the rear of the unit.
2.
The chassis and cabinet of this power source must be grounded to minimize shock hazard. A
chassis ground is provided at the input terminal block. This is located in the front of the cabinet
on the lower left hand side. The lower front cover panel must be removed to access the line
input and ground connections. The chassis ground must be connected to an electrical ground
through an insulated wire of sufficient gauge.
FUSES
Use only fuses of the specified current, voltage, and protection speed (slow blow, normal blow, fast
blow) rating. Do not short out the fuse holder or use a repaired fuse.
DO NOT OPERATE IN A VOLATILE ATMOSPHERE
Do not operate the power source in the presence of flammable gases or fumes.
DO NOT TOUCH ENERGIZED CIRCUITS
Disconnect the power cable before servicing this equipment. Even with the power cable
disconnected, high voltage can still exist on some circuits. Discharge these voltages before servicing.
Only qualified service personnel may remove covers, replace components or make adjustments.
DO NOT SERVICE ALONE
Do not remove covers, replace components, or make adjustments unless another person, who can
administer first aid, is present.
DO NOT EXCEED INPUT RATINGS
Do not exceed the rated input voltage or frequency. Additional hazards may be introduced because of
component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS
Do not modify this instrument or substitute any parts. Additional hazards may be introduced because
of component failure or improper operation.
MOVING THE POWER SOURCE
When moving the power source, observe the following:
1. Remove all AC power to unit.
2. Don not attempt to lift by hand. Raise the levelers and push the unit using two people to prevent
injury or use forklift equipment with a qualified operator.
ALLOW CAPACITORS TO DISCHARGE
Capacitors in the power source may hold a hazardous electrical charge even if the power source has
been disconnected from the mains supply. Allow capacitors to discharge to a safe voltage before
servicing internal circuits or touching exposed pins of mains supply connectors.
