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. American Reliance 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 defective 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 only 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, only qualified personnel who are
aware of the hazard involved should carry out the adjustment, maintenance, and repair.
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.
