2.3 Input Wiring
The IntelliPoint RF instrument utilizes a universal power
supply and can be operated from any source between 85 to 250
VAC or 21 to 100 VDC. The universal power supply
automatically detects the input voltage regardless of
polarity and does not require jumper changes. To access,
remove the housing lid on the CUSTOMER CONNECTIONS
side to reveal the INPUT/ OUTPUT MODULE (IOM) . The
IOM is an encapsulated assembly that contains the power
supply, outputs and eight wiring terminals. The IOM is held
in place with three screws. See Figure 2-3.
WARNING:
If the IntelliPoint instrument is located in a hazardous
environment, do not open the enclosure cover or make/ break
any electrical connections without first disconnecting electrical
power at the source. Ensure that the wiring, electrical fittings,
and conduit connections conform to electrical codes for the
specific location and hazard level.
