3. Check for the lettering on the base. “NO” should be
visible if the power pole is assembled as normally open, or
“NC”, if it is assembled a normally closed (see Figure 3).

2.4 Termination
Power poles can accept wires from #14 to #8 AWG (either
solid or stranded) as single or combination of two wires (refer
to Table B below for valid wire combination). Refer to Table
D on page 3 for the required torque.

AUXILIARY CONTACTS: CR460XB1/XB2
3.1 Description
The auxiliary contact blocks are available in both single pole
(CR460XB1) and double pole (CR460XB2) versions.
Auxiliary contacts can be added on either side of the base (see
Figure 1). When added to the LEFT side of base, the auxiliary
block functions as “NO”, and when added to the RIGHT side
of base it functions as “NC”. Refer to Table D on page 3 for
wire size and required torque.

CONTROL MODULE KITS
The base (electrically held) can be converted to a mechanically
held type by adding the control module kit.
IMPORTANT: The control module kits are for use with the
coils up to 277 Vac maximum. Use a control power
transformer for higher voltages.
Conversion from an electrically held to a mechanically held
type is possible by adding the “control module kit” to the base.
4.1 Description
Control modules kits are available both for 2-wire and 3-wire
control with a wide range of control voltage inputs. Figure 4
shows the components in 2-wire control module kit. A 3-wire
kit includes an additional single-pole auxiliary contact block.
Refer to the Ordering Detail section for more information on
the control module kits and the control voltages available.

4.2 Installation
1. Disconnect all power and mount the control module on the
contactor as shown in Figure 1 (3-wire control type).
2. Mount the latch and the latch cover as shown in Figure 5.
Figure – 5
3. Be sure the latch is firmly in place with the wire facing out
and the slot positioned with tab inserted.
4. Operate contactor manually, using manual operation tabs
on side, prior to installing cover to insure correct
installation.
Note: Once latch cover has been installed, it may not be
removed.
5. For 2-wire control, the auxiliary contact block is
assembled to the right side of the base for “NC”.
IMPORTANT: Latch and electronic module must be used
together to ensure proper operation. Failure to do so will void
warranty.
4.3 Wiring
Follow the schematic (Figure 6) for 2 and 3-wire control.
Refer to Table D on page 3 for wire size and required torque.
Note: For 2-wire control, ensure the two wires coming from
the control module are connected across a NC auxiliary
contact.
