Figure 7.2: AC-PRO-II QUICK-TRIP Switch Drilling Plan
The QUICK-TRIP system is easy to install on the front of the
breaker cubicle door.
To install the QUICK-TRIP Switch:
1. Find a suitable location on the cubicle door and mark
the location of the three (3) holes using the
dimensions in Figure 7.2.
2. Drill two (2) 1/4” mounting holes.
3. For the center hole, cut a 1-3/4” diameter hole using a
hole saw or alternately, use a 1-1/4” conduit knockout
punch (1.73” D).
4. Attach the QUICK-TRIP Switch to the front of the
cubicle door using the two (2) supplied 10-32 screws
and lock washers.
5. Connect the QUICK-TRIP Switch to the AC-PRO-II trip
unit by plugging one end of the 4/C cable provided into
the jack on the back of the QUICK-TRIP Switch. Plug
the other end of the cable into the “QT” jack on the
front of the AC-PRO-II.
6. Route the cable so it does not interfere with the
opening or closing of the cubical door or with the
racking of the breaker between connect and
disconnect positions. Use cable ties and holders to
hold the cable in position.

(provided by others).
Refer to Figure 7.1. If 120VAC (+/- 15%) is applied to the
remote QUICK-TRIP switch terminals, the QUICK-TRIP
settings are activated.
The AC-PRO-II QUICK-TRIP switch includes terminals on
the rear for connection to a customer-supplied remote
QUICK-TRIP indicating light or other device.

**** NOTE ****
QUICK-TRIP protection can be activated (by applying
120VAC to the remote Quick Trip switch terminals)
even when the AC-PRO-II QUICK-TRIP toggle switch is
in the OFF position. Therefore, if a remote
QUICK-TRIP switch is installed, URC recommends
installing label(s) or nameplate(s) that indicate the
presence and location of the remote QUICK-TRIP
switch.
