Insta llation & W iring

1. Mount the appropriate 8, 11 or 12 pin socket in an enclosure.

2. Wire the socket per one of the diagrams below corresponding to your product. Any type of switch (float, manual, timing
relay, pressure, or one with an isolated contact) can be used.

NOTE: If you are using the same control voltage for both the Alternating Relay and the two loads, you must add a
jumper between Terminals 1 & 5 on the SPDT unit or T erminals 2, 6 & 10 on the 11 pin DPDT unit. If using multiple

switches on the DPDT cross-wired units, check to see the proper sequence of switch closures is followed, i.e.,
LEAD before LAG , STOP before LEAD, etc.

3. Set the low-profile selector switch to “AL TERNA TE” for normal operation. In this mode, the unit will operate as a normal
Alternating Relay, alternating between the two loads on each subsequent closing and open of the control switch. Setting
the selector switch to either “LOAD 1” or LOAD 2” will lock the unit to either one of the loads. By locking the Alternating
Relay to one load, the other load can be removed for service without rewiring the first load for continuous operation.
WA RNING: When the selector switch is locked in either the LOAD 1 or LOAD 2 position, it does not disconnect voltage
from the equipment to be serviced.

4. Plug into socket.
