Charging the Mechanism Springs
The mechanism closing springs may also be charged by
the following method:
• Short terminals 17 and 35 on the right terminal
block, with a push button or similar device, for a
minimum of five seconds.
• If power is lost during the charge cycle, finish
charging the springs by cycling the charging handle
until the indicator shows CHARGED on a yellow
background. When the springs are fully charged, the
handle locks in the stored position.
Automatic Operation
Connect terminals 17 and 35 on the terminal block on the
right side of the switch with a jumper wire. The Motor
Operator will automatically recharge the switch closing
springs whenever the switch closes.
CAUTION: Do not wire switches for automatic close.

Padlock Operation
The padlock prevents the switch from closing by holding
the trip latch in the tripped position. To install the
padlock, use the following procedure:
1. Trip the switch (press the
OFF button).
2. Grasp the padlock tab (see Figure 6) and pull it out
until it is fully extended, as illustrated in Figure 8.
Note that if the switch contacts are closed, the
padlock tab will not extend.
3. Insert the padlock; the switch will not close.
As many as three
1 / 4 " to 3 / 8 " padlocks may be attached at
one time.

Periodic Operational Checks
Approximately once a year, verify that the switch is
operating correctly by opening and closing the
mechanism.
Wiring Notes
Figure 9 illustrates the terminal block installed on the
right side of the switch. Table 4 lists the device con-
nections to the terminal block. Each terminal point will
accept the following connections:
• Bare stripped wire – one #12 AWG or two #14 AWG.
• Ring or spade connectors – two per terminal.
The terminal screws should be tightened to 7–9 in-lb
torque.
The left terminal block is blank unless the optional
Auxiliary Switch Module accessory is ordered. See Table
16 for the device connections to the Auxiliary Switch
Module terminal block.
