Use care and proper techniques when positioning the field wires in the
backbox. Be sure to use the minimum required space and avoid undue
stress on the product. This is especially important for stiff, heavy gauge
wires and wires with thick insulation or sheathing.
Do not used more lead length than required when terminating field wires.
Excess lead length may result in insufficient wiring space for the signaling
device. Do not pass additional wires (used for equipment other than the
signaling device) through the backbox. Excessive wires may result in
insufficient wiring space for the signaling device.
