1. Using a #2 Phillips screwdriver, attach the four supplied self-tapping pan
Phillips screws (8B x 1/4”) by screwing them in partially (to allow room to
mount the PAC2) below the modules. (Refer to the illustration below.)
2. Mount the PAC2 in the CAEN (where the screws were attached in step 1),
slide the unit to the right to ensure the screws fully engage the slots in the
flanges, then tighten the screws.
NOTE: For a single-wide CAEN, attach screws on right (screw them in partially),
mount the PAC2 (where the screws were attached in step 1), attach screws on left
and fully tighten all screws.

Bussing Strip Installation
The PAC2 is supplied with two brass bussing strips to facilitate commoning
(linking) of the RELAY OUTPUT terminal block connections. The bussing strips
are constructed with four terminal block positions, and may be trimmed to size for
various applications or different devices. One strip is supplied for each 8-position
terminal block.
1. To utilize the bussing strip, determine the number of relays to be commoned
for the equipment being installed. If less than four, the strip can be trimmed
to size with a pair of scissors or wire snips.
