7.
Plug the connector(s) back into its socket.
8.
Run the cable(s) through conduit to TB301 in the ProCamPAC Output enclosure, using
the knockouts directly above the connector.
9.
Remove the TB301 connector from its socket, and connect wires from the 12-conductor
cable(s) as shown in Table 2-7 (for 8-channel ProCamPAC) or Table 2-7 and Table 2-8
(for 16-channel ProCamPAC). A wire from CHAS to a lug on the ProCamPAC Output
enclosure should already be connected (unless you bought the board assembly only).
10.
Plug the connector(s) back into its socket.
11.
To connect the relays to your equipment, use connectors TB302 and TB303 (see
Figure 2-16).
Specific connections depend on the type of relay you use. For 120 Vac relays, you can
connect wires from your equipment to “C” and either the N/O or N/C side of the relay. If
you connect to N/O, the equipment will be on for the number of degrees set in SmartPAC
2. If you connect to N/C, the equipment will be on except for the number degrees set.
Generally, you should use the N/O terminal so that equipment is off except when you use
SmartPAC 2 to turn it on. Use the N/C terminal only if it is more practical to do the
reverse.
All solid state relays work only when the C and the N/O terminals are connected. Polarity
must be correct for DC solid state relays (refer to Table 2-9.)

INCORRECT SUPPRESSOR INSTALLATION MAY CAUSE RELAYS TO REMAIN ENERGIZED
Ensure that suppressors are correctly installed. They must not be installed across the relay
contacts inside the ProCamPAC Output enclosure. If a suppressor is installed across the relay
contacts and it fails shorted, the equipment controlled by that relay will remain energized.
Failure to comply with these instructions could result in death or serious injury.
