STEP 1: Installing Control Units
This section shows how to install Control Units and make sure they are properly operating all connected loads.
CAUTION!
First test loads for short circuits.
1. Turn power OFF at the breaker/MCB panel or fuse box.
2. Connect standard light switch between live lead and the load wire to test circuit.
3. Turn power on and check for short or open circuits: If load does not operate, circuit is open. If the
breaker/MCB trips (fuse blows or opens), circuit is shorted. Correct short or open circuits and test
again.
Load Types
The Control Units can control incandescent, halogen (tungsten), magnetic low-voltage, and neon/cold cathode load types. Electronic lowvoltage and fluorescent load types can be controlled with an appropriate interface.
■ Not all zones need to be connected; however, connected zones must have a load of at least 25W (40W for AU and CE models).
■ No zone may be loaded with more than 800 W (1200 for AU models).
■ Unit must not carry more than 16A of total lighting load (10A for CE models).
■ All Electronic Low-Voltage (ELV) lighting used with the Electronic Low-Voltage Interface must be rated for reverse phase-control
dimming. Before installing an ELV light source, verify with the manufacturer that their transformer can be dimmed. When dimming, an
Electronic Low-Voltage Interface MUST be used with the Series Control Unit.
Installation instructions. First, turn power off.
Preparation
1. Mount Wallbox. Use standard U.S. wallbox, 3 1/2 in. (87 mm) deep is strongly
recommended, 2 3/4 in. (68 mm) deep minimum. Always allow at least 4 1/2 in. (110 mm)
clearance above and below the faceplate to ensure proper heat dissipation.
2. Pull Wires. Use the rearmost knockouts when pulling wires into the wallbox. This will
provide the most clearance when mounting the Control Unit.
3. Remove Cover. Remove the Control Unit’s cover and hinged faceplate by pulling outward at
each corner.

Line Voltage/Mains Wiring
IMPORTANT WIRING NOTES!
■ Use properly certified cable for all line voltage/mains cables and
Class 2/PELV cables.
■ In Europe, acceptable types of cable include HAR certified cable
with insulated cores enclosed in a sheath. This cable must bear the
appropriate certification mark pertaining to national wiring rules for
fixed installations. If certified cable with insulated cores enclosed in
a sheath is used for the Power cables, the Class 2/PELV wiring can
be any of the specified cables in Appendix A: More about
Class 2/PELV Wiring.
■ Proper short-circuit and overload protection must be provided at
the distribution panel. You can use up to a 20A (16A for AU, and
10A for CE models) maximum circuit breaker/MCB or equivalent
(tripping curve C according to IEC60898/EN60898 is
recommended) with adequate short-circuit breaking capacity for
your installation.
■ Install in accordance with all local and national electrical codes.
■ CAUTION! Do not connect line voltage/mains cable to Class 2/
PELV terminals.
■ Earth/Ground terminal connection must be made as shown in
wiring diagrams.
■ Do not mix different load types on the same zone!
■ Fluorescent and electronic low voltage loads require
interfaces. Zone loads that exceed 800W/VA (1200W/VA for
AU models) and total unit loads that exceed the unit capacity
require power boosters. Refer to Appendices C, D, E, and F.
Wire the Control Unit (see Page 16)
1. Strip 1/2 in. (12 mm) insulation from all wires in wallbox and
connect them to appropriate terminals on the back of the
Control Units. The recommended installation torque is 9.0
in.
●
lbs. (1.0 N●m) for line voltage connections and 10 in.●lbs.
(1.3 N
●
m) for the earth/ground connection. Each power
terminal can accept up to two #12 AWG (2.5 mm
2
) wires. (Does
not apply to Class 2/PELV terminal block.)
