Connecting AC Power
The J-box comes wired for 120Vac and has a 2m
(6ft-7in) SJT 3-conductor power cord attached.
Plug the cord into a dedicated 24-hour,
unswitched outlet.
If the box is to be driven by 240Vac, then the
power cord (if used) and jumpers across the
primary winding of the transformer within the box
will have to be changed (Figure 6).
CAUTION: Use only regulatory-approved
polarized power cords.
Hardwiring the J-Box
If the box is to be hardwired to the ac source, then
the chassis within the box and the power cord will
have to be removed to facilitate connection. Refer
to Figures 5, 6, and 13 for how to remove these
parts.
CAUTION: Keep the disconnect device (circuit
breaker) readily accessible when hardwiring J-box.
Do the following:
1. Unplug line cord from ac outlet.
2. Loosen two screws, then slide and lift circuit
board assembly to remove and access ac
connections (Figure 5).

Data Cable Requirements
Wires within the data cable are organized in two
polarized 22AWG, shielded, twisted pairs. Up to
1km (3000ft) of data cable can be run from the
Host to the J-box, or from J-box to J-box (see
CAUTION below). For more information about the
RS-422 communication protocol and possible
cable network configurations, see Communication
Protocols and Cable Networks, 8000-2573-19.
CAUTION: Data cable from the J-box to the dome
is limited by the length of the power cable. See
Table 1 above.
Note: Power, data, and video cables can be
ordered separately or within a composite cable
ordered in various lengths. Plenum-rated cables
must be used in indoor ceilings used for
environmental air return (called “other air space” in
the National Electrical Code). Order parts through
your distribution network. If you order cable from
an outside source, wire colors may be different.
