Note If you are also installing the optional NiMH battery/bracket assembly now,
remove and retain the other two screws, that is for the other option slot.
Step 6 Carefully insert the pins of the option card into the socket headers of the
option card slot.
The mounting holes on the option board should line up with the standoffs
on the base board. If they do not, the connector is not properly aligned.
Press until the option card is completely seated.
Step 7 Place the custom end plate for the option card over the connector(s) of the
option card. With some option cards, the card’s end plate is pre-fastened.

a Plug the battery connector plug into the battery connector on the control-
ler’s base board.
b Set the battery and bracket assembly over the option card slots, with the
mounting holes aligned with the standoffs.

on the controller base board. With a screwdriver, hand tighten the screws.

About Accessory Modules
The controller has a 20-pin, right-angle, Euro-DIN connector that accepts
custom-built accessory modules. The connector provides power and signal lines to
any connected modules.
Warning • Power to the controller must be OFF when inserting or unplugging
accessory modules. Wait for all LED activity to stop (all LEDs off).
• Also, do not connect live voltages to the inputs or outputs of an I/O
module while it is in an “un-powered state” before plugging the
module into the controller.
Otherwise,
damage to the I/O module and/or controller may result
!
Each accessory module has a DIN-mount base, and typically provides two (2) 20-pin
connectors that allow you to “chain” multiple accessories. Tab le 2 lists the currently
available modules.
