The kit includes a special cable to allow simple interconnection 

between the controller and the OpenComms NIC.

Retrofit kits are designed specifically for individual units. Consult 

your local sales / service representative for pricing, part numbers and 

installation help.

As a minimum there will be an IFM board (communications interface) 

mounted at the mid-point on the door. Other options may also have 

been previously installed.
The Option boards mount on the inside of the option door. Options can 

be located in any available option slot, however the OpenComms 

NIC should be mounted in the bottom most (bottom cable entry) posi-

tion.

After mounting the NIC card in the uppermost or lowermost option 

position, per the instructions above, route the wire harness from TB3 

on the lower left of the NIC card to the power supply board on the back 

of the control door. Follow the routing path indicated in Figure 7.

Connect the 2-wire harness from TB1 on the bottom center of the NIC 

card to TB55 on the IFM card. The board is now ready to connect cus-

tomer inputs, which should be routed from either the top or bottom 

cable entry points.
Refer to the NPower option manual for any further details on installa-

tion.
