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 identifiable and is easily reached by the
operator) may be used as a disconnecting device.
6. Install the analyzer according to the enclosure protection provided.
This instrument does not protect against the ingress of water. It does
protect against finger access to hazardous parts within the enclosure.
7. Ensure there are at least two inches of clearance around the sides
and back of either the stand-alone analyzer or the system cabinet.
