Plug the connector(s) back into its socket.
11.
To connect the relays to your equipment, use connectors TB302 and TB303.
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 (normally open)or N/C (normally closed)
side of the relay
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 2-10.)

WARNING
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.
12.
To reduce electrical noise and to extend the life of the relays, do the following:
AC loads:
Install arc suppressors across each inductive load (motors, coils, etc.) that is connected to a cam
relay (see Figure 2-15). Suppressors are supplied with each relay. Install the suppressors across
the load or as close to the load as possible. Attach suppressors by connecting leads across existing
terminals or junction points.
DC loads:
Install a diode across each DC load, (see Figure 2-16)
