Installing the Analyzer
Step 2. Meet Electrical and Environmental Requirements
WARNING
If this instrument is to be energized via an external autotransformer for
voltage reduction, make sure that its common terminal is connected to a
neutral (earthed pole) of the power supply.
5. Install the analyzer so that the detachable power cord is readily
identifiable and is easily reached by the operator. The detachable power
cord is the instrument disconnecting device. It disconnects the mains
circuits from the mains supply before other parts of the instrument.
The front panel switch is only a standby switch and not a LINE switch.
Alternatively, an externally installed switch or circuit breaker (which is
readily
identiliable
and is easily reached by the operator) may be used as a
disconnecting device.
6. Ensure there are at least two inches of clearance around the sides and
back of either the stand-alone analyzer or the system cabinet.
