2-68 Installation
9.
Remove the TB301 connector from its socket, and connect wires from the 12-conductor
cable(s) as shown in Table 2-22 (for 8-channel ProCamPAC) or Table 2-22 and
Table 2-23 (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 2-33).
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 2-24.)

Module How To Connect Type
Relay One wire to C, one wire to N/O or N/C, polarity does not matter

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.
