9040 Cascade Low Voltage Control Unit - Installation
The wiring from the user supplied external
overload reset device can be connected directly
to the outside terminals 2PL-2 and -3 (remove
factory installed jumper from 2PL-2 to 2PL-3), or
for installations requiring conduit, connected to the
inside terminals 2SOC-2 and 3 as follows:
1. Remove the factory-installed jumper from 2PL-
2 to 2PL-3.
2. Ensure the front panel fuse is removed, the
control unit is unplugged, and the ON/OFF switch
is in the OFF position.
3. Loosen the front panel screws and slide the
control unit chassis out.
4. Route the contact wires of the external reset
device through the external wiring grommet
opening and connect to the existing wiring for
2SOC-2 and 2SOC-3. The external reset

If a method of high voltage triggering, other than
the factory supplied method, is required, the 9040
Cascade control unit allows for external high
voltage control from a PLC, pressure switch,
airflow switch, or other user-supplied device. To
turn the high voltage on, the user-supplied device
must create a contact closure between terminals
1 and 2 of the External Wiring Plug (2PL). The
wiring from the user-supplied external high voltage
control device can be connected directly to the
outside terminals of 2PL, or for installations
requiring conduit, connected to the inside terminals
2SOC-1 and 2 as follows:
1. Ensure the front panel fuse is removed, the
control unit is unplugged, and the ON/OFF switch
is in the OFF position.
2. Loosen the front panel screws and slide the
control unit chassis out.

NOT be used to trigger the high voltage
for multiple control units.

The 9040 Cascade control unit allows for use of
an external (normally closed) overload reset
button. This is convenient when the control unit
is mounted in a hard to reach or inconvenient
location or when it is desired to control overload
reset of several control units from a single location.
