_________________________________________________________________________________________
SAFETY SUMMARY
NOTE: The following general safety precautions must be observed during all phases of operation of this instrument.
Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended use of the instrument.
AMETEK Programmable Power, Inc. assumes no liability for the customer’s
failure to comply with these requirements.
WARNING
Servicing instructions are for use by service-trained personnel. To avoid dangerous electrical shock, do not perform any
servicing unless you are qualified to do so. Some procedures described in this manual are performed with power supplied
to the instrument while its protective covers are removed. If contacted, the energy available at many points may result in
personal injury.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is designed to
operate at maximum relative humility of 95% and at altitudes of up to 2000 meters. Refer to the specifications for the ac
mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to the appropriate line voltage, the correct line fuse is installed, and all safety precautions are
taken.
GROUND THE INSTRUMENT
Before switching on the instrument, the protective earth terminal of the instrument must be connected to the protective
conductor of the main power cord. The mains plug shall be inserted only in an outlet socket that is provided with a
protective earth contact. This protective action must not be negated by the use of an extension cord that does not have a
protective conductor. Any interruption of the protective grounding or disconnection of the protective earth terminal will
cause a potential shock hazard that could result in personal injury.
FUSES
Only fuses with the required rated current, voltage, and specified type should be used. Do not use repaired fuses or short-
circuited fuse holder. To do so could cause a shock or fire hazard.
AVOID ACCESS TO LIVE CIRCUITS
Operating personnel must not remove the instrument cover. Component replacement and internal adjustments must be
made by qualified service personnel. Do not replace components with the power cable connected. Under certain
conditions, dangerous voltage may exits even with the power cable removed, to avoid injuries, always disconnect power,
discharge circuits and remove external voltage sources before touching components.
AVOID TROUBLESHOOTING ALONE
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is
present. Any adjustment, maintenance, and repair of this instrument while it is opened and under voltage should be
avoided as much as possible. If this is unavoidable, adjustment, maintenance, and repair should be carried out by only
qualified personnel who are aware of the hazard involved.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Because of the danger of introducing additional hazards, do not install substitute parts or perform an unauthorized
modification to the instrument. Return the instrument to an American Reliance Service Department for service and repair
to ensure that safety features are maintained.
