SAFETY NOTICE
Before applying power to the system, verify that the instrument is configured properly for the user’s
particular application.
WARNING!
Hazardous voltages may be present when covers are removed.
Qualified personnel must use extreme caution when servicing
this equipment. Circuit boards, test points, and output voltages
also may be floating above (below) chassis ground.
Installation and servicing must be performed by qualified personnel who are aware of dealing properly
with attendant hazards. This includes such simple tasks as fuse verification.
Ensure that the AC power line ground is connected properly to the chassis. Similarly, other power
ground lines including those to application and maintenance equipment must be grounded properly for
both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration,
HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure
that the output power lines are labeled properly as to the safety hazards and that any inadvertent
contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Due to filtering, the unit has high leakage current to the chassis. Therefore, it is essential to operate this
unit with a safety ground.
Some circuits are live even with the front panel switch turned off. Service, fuse verification, and
connection of wiring to the chassis must be accomplished at least five minutes after power has been
removed via external means; all circuits and/or terminals to be touched must be safety grounded to the
chassis.
These operating instructions form an integral part of the equipment and must be available to the
operating personnel at all times. All the safety instructions and advice notes are to be followed.
Neither Elgar Electronics Corporation, San Diego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for personnel, material or inconsequential injury, loss or
damage that results from improper use of the equipment and accessories.
