Potentially hazardous voltages are present. Turn off all power supplying this equipment before connecting or disconnecting wiring.

Warning

Installation & W iring

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

2. Wire the socket per one of the diagrams at right corresponding to your product or as shown
on the side of the product.

3.(No “R” suffix) Products w ithout the 8-pos ition rotary sw itch w ill operate as a no rmal Triplexor
with three inputs.

4.(“R” suffix) Products with the optional 8-position rotary switch can be used as either:

(a) a standard Triplexor with three inputs
(b) a Triplexor locking Load 1, 2 or 3 as the first to be energized (Lead Load)
(c) a standard Duplexor with two inputs until system expansion requires a third Load
(d) a Duplexor locking Load 1 or 2 as the first to be energized (Lead Load)

8 Pin

(A1 & A1R suffix)

Rotate the switch to the desired function. Note: do not change the setting of this switch
with power applied to the unit.

5. Plug the product into the socket.

6. If power i s lost & returns with m ore than just t he LEAD Switch cl osed, there i s a fix ed 10
second delay betwee n energization of the LAG ou tput (Triplex & Duplex mode) & LAG2 ou tput
(Triplex mode only) to prevent all Loads from coming on at the same time.

7. One of the Red LED’s w ill be steady ON to indicate which Load will be energized first; all will
flash (3 in Triplex mode or 2 only in Duplex mode) to indicate a switch out-of-sequence error.

12 Pin

(A7R suffix)

Triplex Operation

All three switches are open and all loads are off. When the LEAD Switch
closes, it energizes Load 1. As long as the LEAD Switch remains closed,
Load 1 remains energized. If the LAG Switch closes, Load 2 is energized.
If the LAG2 Switch closes, it energizes Load 3. Each load is turned off in
sequence as the switches are opened. The entire cycle is then repeated,
but with Load 2 energized first followed by Load 3 and then Load 1.
NOTE: the power for all outputs is supplied from the L connection, not
through the input switches (see drawing at right). NOTE: in Duplex mode
(“R” suffix), the LAG2 input & the Load 3 output are non-functional.
