Electrical Installation
If the NIB is mounted to a CHS-4...
Connect the main power harness from the MPS power supply to P3 on the NIB.
Connect the short power harness (provided) from P2 on the NIB to the ICA-4/4L If
additional NIBs are installed, the power harness is daisy-chained through all NIBs.
If the NIB is mounted to an ICA-4/4L...
All power connections are completed through the ICA-4/4L connection.
Referring to the terminal assignment table below, connect the EIA-485 input on the
NIB to the EIA-485 connector on the slave AFP-200. If the slave AFP-200 also has
annunciators, the EIA-485 OUT terminals on the NIB are used to daisy-chain to
these additional EIA-485 devices.
Connect the LIB SLC loop from the master AM2020/AFP1010 to the NIB's SLC in-
put terminals. Typically, each NIB is connected to a single LIB in the master
AM2020/AFP1010 and uses almost all of the module capacity (96 out of 99 maxi-
mum) of that LIB SLC.
