3) CONNECTING AUX (Auxiliary Contact Switch) - The National Electrical Code requires
that when a secondary power supply or battery is used, the main disconnect must be
provided with an auxiliary switch that will open when the disconnect switch is opened.
This is a safety device and must be provided by the electrical contractor.
4) BATTERY POWER SUPPLY (Emergency Lowering/Emergency Lights) - Two (2) 12 volt
batteries are installed in the main control enclosure on the car. When servicing the
controls, the battery must be disconnected. To test the operation of the emergency
lowering battery supply, open the 110 volt power disconnect and the main power supply.
The emergency light will illuminate and the elevator will run in the DOWN direction only.
NOTE: For this test, the auxiliary switch will have to be temporarily jumped.
HALFWAY JUNCTION BOX
The Halfway Junction Box is installed in the hoistway, typically mounted on the rail wall outside
the rails, but if there is room, the box may be mounted on any wall without a door. The box
should be situated vertically, approximately two (2) feet (610 mm) above the halfway point of
the elevator travel. Mount the Halfway Junction Box using four (4) #10 x 1 -1/2" wood screws
or anchors, as required.
SHAFT WIRING MUST BE DONE IN ACCORDANCE
WITH LOCAL CODES AND REGULATIONS. CHECK

should be installed about 4 feet (1219 mm) above the
lower landing level, where it can be easily reached
while standing in the door opening.
2) Run wiring or conduit from the Pit Switch to the
Halfway Junction Box. Use proper fastening methods
and ground wires.
