Overview

The 4 Series Low-voltage Rough-in Enclosure pro-
vides a compact housing for mounting the 4 Series
processor. The enclosure accepts one 120 V feed
to power the processor and its connected keypads.
The enclosure's main feed is self-contained in an
enclosed high-voltage area, eliminating exposure of
high voltage connections when the enclosure cover is
removed for low-voltage wiring. In addition to the
processor, up to 2 contact closure boards (HWI-CCO­8 or HWI-CCI-8) and/or wire landing boards (HWI­WLB) may be mounted in the 24 in. (70 cm) enclo­sure. Contact closure outputs provide low-voltage con­trol of motors and shades. Contact closure inputs
allow interfacing to photocells, security systems, and
other home systems. The wire landing board is a
wiring aid with three sets of four terminal blocks con­nected pin-to-pin, simplifying home run wiring.

Important Notes

Codes: Install in accordance with all local and nation-

al electrical codes.

Note: Enclosure must be protected by an
appropriately rated (min. 15 A) circuit break­er, to be supplied and installed in accordance
with local codes by the installer.

Mounting Location: Power supply will hum slightly
and internal relays will click while in use. Mount in a
location where such noise is acceptable.

Environment: Ambient operating temperature:
0-40°C, 32-104°F, 0-90% humidity, non-condensing.
Indoor use only.

Cleaning: To clean, wipe with a clean damp cloth.
DO NOT use any chemical cleaning solutions.

Wiring Diagram

1. Mount Enclosure using one of the following methods

(mounting hardware is not provided):
a. Surface Mount - Use keyholes shown in Mounting

Diagram (page 1)with bolts sufficient for 30 lbs. (14
kg) load (1/4 in. (M6) bolts recommended).

b. Recess Mount - Use screws sufficient for 30 lbs.

(14 kg) through the sides of the enclosure (see
Mounting Diagram, page 1). Mount enclosure flush to
or not more than 1/8 in. (3 mm) below the finished wall
surface. Enclosure is 3-7/8 in. (10 cm) deep past
cover mounting tabs. Enclosure cover dimensions are
24-1/2 in. x 15-7/8 in. (62 cm x 41 cm).

Danger - Locate and lock supply breaker in the
OFF position before connecting power input.

2. Remove high voltage cover and run power wiring

into the enclosure. Locations to run power wiring into

the enclosure are as shown in Wiring Diagram. Prepare
wires. When making wire connections, follow the recom­mended strip lengths and combinations for the supplied
wire connectors. Note: Wire connectors provided are suit­able for copper wire only.

Connect Hot/Live feed to the black wire, Neutral feed to
the white wire, and Earth Ground to the green wire.
Replace high-voltage cover.

3. If the processor and the accessory boards are not to
be installed at this time, install the enclosure cover.

(Instructions for installing the processor and accessory
boards are supplied with the processor). Ensure product
identification label is at the bottom of the cover. Tighten
screws to 20 in.-lbs. (2.3 Nm).
