5.4Wire 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.

Wire Size mm2	Wire Size AWG	Housing Distance
0.5	20	27 m (90 ft)
1	18	42 m (140 ft)
1.5	16	67 m (220 ft)
2.5	14	108 m (355 ft)
4	12	172 m (565 ft)

Table 5.1 Maximum cable lengths for 24 V camera housings

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 mm2 (14 AWG) require a splice to accommodate the terminal block. The terminal block accepts wires ranging from 0.5 to 2.5 mm2 (20 to 14 AWG). When using 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.
