GE BM-A301US5-O2 Switch User Manual

The GE Time Switches (56922, 15087, 15207) are universal, electromechanical
time switches which can be field configured for various power supply
voltages. The voltage options include 120VAC, 208/240VAC and 277VAC – all
within the same unit! Selection of the desired supply voltage is easily achieved
by positioning dipswitches on the printed circuit board assembly (consult
Dipswitches Configuration on back). The mechanism is mounted in a NEMA
indoor or outdoor enclosure and is intended for the control of lighting, heating,
air conditioning, pumps, motors, or general electrical circuits in residential,
commercial, industrial and agricultural facilities.
Input Voltage: 120 VAC, 208/240 VAC, or 277 VAC in all units based
upon dipswitch configuration.

CAUTION: Before wiring or servicing, power to this time switch and the
equipment it controls must be turned off. Turning off the time switch only
will not prevent a shock hazard. Replace cover plate within housing before
supplying power to time switch. If you are not comfortable installing this
device please contact a licensed electrician. Before installing this product read
all instructions carefully.
Removing Knockout
1. Select knockouts to be used. Remove the inner 1/2” knockout by inserting
a flathead screwdriver on the inner most ring and carefully punching the
knockout loose. Remove slug. If the 3/4” knockout is required, remove the
outer ring with pliers after removing the 1/2” knockout. Smooth edges with
a knife if necessary.
Please refer to Quick Start Guide for Examples and More Details.
Mounting of the Time Switch Box
NOTE - Before mounting be sure to remove knockouts for the wires, (see Quick
Start Guide)
1. In order to mount the box you will need the 3 supplied anchors and 3
supplied screws from the hardware list above. (Anchors included are
designed for mounting on sheetrock.)
2. Using the box as a template, mark with a pencil where the three pilot holes
will be drilled.
