SK-Control-6 modules.
FIGURE 1: IDP-ACB CABINET
The front SK-Control-6 module positions of each chassis are offset below the
rear SK-Control-6 module positions so that all of the status indicators are vis-
ible. For cabinet dimensions refer to the IDP-ACB instruction manual.

Module Installation
There are two methods for installing a module in the rear position of a
chassis. Method one is for installation of a rear module only, when no
module will be installed in front of it. Refer to Figure 3 for instructions.
Method two is for installation of a rear module when another module
will be installed in the chassis position in front of it. Refer to Figures 4a
and 4b for method two. All necessary screws and standoffs are supplied
with the modules.

Step 1:
Insert the bottom of the SK-Control-6 module down into a rear slot
on the chassis.
Step 2:
Carefully swing the upper edge of the board back towards the back
of the chassis until it touches the two standoffs.
Step 3:
Align two 4-40 screws with the two standoffs and tighten.
Step 4:
Address and wire the modules according to the instructions in this
manual.
The steps in Figures 4a and 4b describe and illustrate module installation
when the rear chassis position and the position in front of it will be filled.
Front position installation is possible only if the rear position is filled with a
module.
