3645A-TYPE USER’S MANUAL
Before switching on the DC Power supply, the protective earth terminal of this in-
strument must be connected to the protective conductor of the AC line power cord. The
AC line plug shall be inserted only in a socket outlet provided with a negated by the use
of an extension cord (or power cable) without a protective grounding conductor.
The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these precau-
tions or with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended use of the instrument. The Manufacturer assumes
no liability for the customer’s failure to comply with these requirements.
Ground the Instrument
This product is provided with a protective earth terminal. To minisize shock hazard,
the instrument chassis and cabinet mush be connected to an electrical ground. The
instrument must be connected to the AC power supply mains through a three-conduc-
tor power cable, with the third wire firmly connected to an electrical ground (safety
ground) at the power outlet. For instruments designed to be hard-wired to the AC power
lines (supply mains), connect the protective earth terminal to a protective conductor
before any other connection is made. Any interruption of the protective (grounding)
conductor or disconnection of the protective earth terminal will cause a potential shock
hazard that could result in personal injury. If the instrument is to be energized via an
external autotransformer for voltage reduction, be certain that the autotransformer com-
mon terminal is connected to the neutral (earthed pole) of the AC power lines (supply
mains).
Keep Away From Live Circuits
Operating personnel must not remove instrument covers. Component replacement
and internal adjustments must be made by qualified service personnel. Do not compo-
nents with power cable connected.
Under certain conditions, dangerous voltages may exist even with the power cable
removed. To avoid injuries, always disconnect power, discharge circuits and remove
external voltage sources before touching components.
Do Not Substitute Parts or Modify Instrument
Because of the danger of introduction additional hazards, do not install substitute
parts or perform any unauthorized modification to the instrument. Return the instru-
ment to a qualified dealer for service and repair to ensure that safety features are
maintained.
