Wire Preparation

Supply the UHI-SBG-0 with power by using a power cord that complies with the Nec 400-4
CEC rule 4-010 and is marked with INDOOR, W or W-A. For 24 V cameras, use the recom-
mended maximum cable length chart for selecting the proper wire size.

Preparing the Power Supply
Cut the power cord on 120 VAC and 230 VAC camera models; leave enough cable to allow a
connection to the terminal block. Strip no less than 6 mm (0.25 in.) and no more than 8 mm
(0.31 in.) of insulation away from the wire. Do not nick the wires.
Preparing the Terminal Block
Wire sizes larger than 2.5 mm
The terminal block accepts wires ranging from 0.5 to 2.5 mm
larger wire sizes, splice to a smaller size wire at the terminal block end. The splice may need
to be enclosed in a junction box if it does not pass through the fittings.
