4.1.8 DC Power Wiring Installation
A 15-foot connectorized 3-wire cable (also available in lengths of 40, 60, or 100 feet) is
provided for the DC power connections. The connectorized end of the cable connects to the
DC power port located on the bottom of the enclosure. The stub end of the cable must be
routed to an external junction box (not provided) for permanent connection to the DC power
system wiring. The DC power source must supply 5 amps at -48 VDC through a 5 amp circuit
breaker. The DC power cable provides three wire leads for positive, negative, and ground con-
nections. The power cable is rated for indoor or outdoor use and must not be placed within
electrical conduit as this will impede the cooling of the cable during usage. The electrical
junction box and any conduit, wire, and fittings required must be provided by the installer.
DANGER: While trying to connect the AC power cable to the remote unit AC power port, it is
possible for the line terminal on the cable connector to contact the ground pin on the power port. If the
AC cable is energized, this will result in a direct short to ground for the AC power. To avoid possible
personal injury and equipment damage, always turn the AC power off before connecting the AC power
cable to the AC power port.
