Note: Output modules must be installed from left to right without open connector positions in between. The timing mechanism
will not recognize any output module installed to the right of an open connector position. The middle 11-pin connector is not
used on the back distribution board and is not considered an open connector position.
8. Starting at the left side of the distribution PCBA, carefully install an 8-station output module onto the first 16-pin module connector.
Make sure the socket at the top of the module is correctly aligned with the connector pins before pressing the module into position.
Secure the module with a single #6 screw as shown in Figure 3. Install up to three additional output modules in this manner.
Note: Do not force the module into position on the distribution PCBA. If the connector pins are correctly aligned, the module
will slide into position with only slight resistance.
9. Install a plastic retainer, flat washer and #6 screw (supplied with the output module) on each of the upper bosses to secure
the output module(s) to the distribution PCBA. See Figure 4.
10. Plug the optional 16-output surge module into the receptacles of the two 8-station output modules and secure with four #6 screws
as shown in Figure 5. If installing the optional 8-station terminal block, simply plug it into the output module receptacle as shown
in the inset in Figure 5.
11. Route the ground wire from the 16-output surge module to the ground buss (located to the left of the power supply housing).
Install the ring terminal onto the stud and secure with an #8-32 self-locking nut (provided). See Figure 6.

CAUTION: Each 16-output surge module must be grounded to enable the surge suppression components to function.
Surge damage can occur if the controller is not properly grounded.
12. Install the jumper wire assemblies to the front distribution PCBA as shown in Figure 7.
Note: The ribbon cable blue orientation stripe must be on the left side (when facing the cable/socket).
13. Install the jumper wire assemblies to the back distribution PCBA as shown in Figure 8. This will require making a twist in the
jumper cables to install correctly.
14. Place the power supply switch in the On (O) position.
