To determine if the module mounting unit uses -30 VDC:
1. Locate the -30 VDC faston. It is the second faston from the
top when viewing the module mounting unit from the rear.
2. Check for -30 VDC with respect to system common at the
-30 VDC faston.
3. If -30 VDC is present, set jumper J5 of the NPM module to
the appropriate position.
To install the NPM module:
1. Verify the NPM module slot assignment in the module
mounting unit is adjacent to its associated NIS module.
2. Verify that a 24-pin dipshunt is installed in the I/O
expander bus sockets between the module mounting unit slot
to be used by the NIS module and the slot to be used by the
NPM module.
NOTE: When installing redundant NPM modules, each NPM mod-
ule must be connected to its own NIS module on the I/O expander
bus. Do not connect the individual I/O expander buses that belong
to each set of redundant modules.
3. Remove any 24-pin dipshunts from the I/O expander bus
sockets that would connect the NPM module to any module
other than the NIS module.
4. In redundant process control unit interface applications,
connect one end of the NKMP01 or NKMP11 cable to the rear of
the module mounting unit slot assigned to the primary NPM
module.
5. Connect the other end of the NKMP01 or NKMP11 redun-
dancy cable to the rear of the module mounting unit slot
assigned to the backup NPM module.
6. Slide the NPM module in while guiding the top and bottom
edges of the circuit board along the top and bottom rails of the
module mounting unit.
CAUTION
To avoid potential module damage, evaluate your system for
compatibility prior to module installation. This module uses
connections to the module mounting unit backplane that
served other functions in early Network 90 systems.
WARNING
Disconnect power before installing dipshunts on the module
mounting unit backplane. Failure to do so will result in contact
with cabinet areas that could cause severe or fatal shock.
