®
PANEL. DISCONNECT BOTH SOURCES OF POWER BEFORE
SERVICING. FAILURE TO DO SO COULD RESULT IN PROPERTY DAMAGE,
SERIOUS INJURY, OR DEATH TO YOU AND/OR OTHERS.
CAUTION: Connect the AC power source before connecting the battery backup power. Disconnect
the battery backup power before disconnecting the AC power source.

Wiring Guidelines
Although the SAFEPATH
Panel products incorporate signal verification and noise filtering circuitry on
their inputs, induced voltages or noise on the input wiring can cause improper operation. Therefore, use
shielded twisted pair wire for all dry contact input wiring.
The shield of each cable should be connected only at one end. Each shield of each cable that
connects to the SAFEPATH
Panel is to be connected to the grounding points provided near the
knockout locations on the chassis (see Figure 3-17 on Page 3-15).
The National Electrical Code (NFPA-70) defines two types of circuits for protective signaling systems:
power limited circuits and non-power limited circuits. The SAFEPATH
®
Panel circuits are non-power
limited.
WARNING: ALL SAFEPATH
®
PANEL DRY CONTACT INPUT WIRING AND AUDIO WIRING
SHOULD BE ROUTED AWAY FROM ANY HIGH VOLYAGE OR HIGH CURRENT
WIRING (SUCH AS AC OR DC POWER WIRING, AUDIO POWER WIRING, AND
MOTOR OR RELAY ACTUATION WIRING). DRY CONTACT INPUT WIRING SHALL
BE INSTALLED IN SEPARATE CONDUIT. FAILURE TO DO SO MAY CAUSE
ELECTRICAL SHOCK RESULTING IN PROPERTY DAMAGE AND SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS.
