Step 2 Mount Dimmer Chassis

2.1. Mounting Requirements

Mounted vertically on a flat surface.

A clearance of at least 50 mm on all sides of the unit to allow for adequate

ventilation. The grilles must NOT be obstructed.

Sufficient clearance must be left to allow for the connection of cables and trunking.

The ambient temperature must be within the range of 0ºC to 40ºC and the area

must be adequately ventilated.

Humidity must be within the range of 0% to 90% (non-condensing). Do NOT install

this product in a damp location.

2.2. Mounting Procedure

Use 4 screws (not provided) to mount to

the wall (No.8 or No. 10 screws with a head

diameter greater than 6 mm and less than

9 mm).

Note 1 Use the mounting holes located

at the furthest corners of the

chassis.

Note 2: If you are replacing an Imagine

dimmer, e.g.HES99400, and are

using the existing screw

locations, then you can use the

two holes at the top and the two

in the middle.

Note 3: Use wall plugs, if necessary.

Step 3 Electrical Installation

WARNING: BEFORE COMMENCING ANY ELECTRICAL WORK, ISOLATE THE

ELECTRICITY SUPPLY AT THE MAIN DISTRIBUTION BOARD.

Mains Supply Voltage Range

The dimmer is designed for use with the following voltage range:

85 to 264 VAC (absolute); 110 VAC / 230 VAC (nominal).

Mains Supply Protection

The mains supply input must be externally protected by an MCB or fuse of a suitable

rating.

WARNING: THE SUPPLY INPUT MUST ONLY BE CONNECTED TO A SINGLE-

PHASE SUPPLY. THE SUPPLY INPUT EARTH MUST BE CONNECTED.

Using Spring-Lever Cage Clamp Terminals

Note: The supply earth, supply neutral and output terminals are spring-lever cage

clamp terminals.

1. Insert a screwdriver as far as it will go into the terminal release point.

2. Lever the screwdriver back. This opens the cage clamp. (For output terminals,

levering the screwdriver back is unnecessary).

3. With the cage clamp open, cable can be inserted or removed from the terminal.

4. Release the pressure on the screwdriver and then remove it. This closes the cage

clamp. If you have inserted a cable, check that the connection is secure.

3.1. Connect the Mains Supply Input

Connect the mains supply input to the MCB and earth and neutral terminals, as shown

in the diagram below.

3.2. Connect the Loads

Connect the loads to the output terminals, as shown below.

Step 4 Attach Module and Make Connections

WARNING: BEFORE ATTACHING THE MODULE AND MAKING ANY

CONNECTIONS, ENSURE THAT THE MAINS SUPPLY IS STILL ISOLATED.

Re-assemble the dimmer module to the chassis before making any connections.

4.1. Connect Module Supply and Dimmer Channels

1. Remove the cables from the bypass terminals and connect them to the channel

terminals.

(Ensure that the terminal numbers correspond to the channels numbers).

2. Connect the supply to the module.

Note: The bypass terminals allow operation and testing of the lights and installation

wiring. The supply cable is supplied disconnected.

The dimmer may be controlled by either DALI or S-DIM, but DO NOT CONNECT

BOTH AT THE SAME THE TIME.

Note: Use the cable sleeving (supplied) to provide an extra layer of insulation

between the S-DIM, TouchPanel and Override low voltage signal wires and

other wiring.

S-DIM

If connecting to an Imagine system, connect to the S-DIM terminals.

If the dimmer is at the end of the S-DIM cable, wire between the ‘TERM’ and ‘B’

connections of the S-DIM terminals to enable the cable termination.

TouchPanel

You can supply one TouchPanel from the TouchPanel power connection terminal.

Override

If you wish to provide output level override functionality, wire between the ‘–/0V’ and

‘OVR’ connections of the override input connection terminal. This sets the light output

of all dimmer channels to the override level (the default is 100%, but can be changed).

DALI

If connecting to a Digidim system, use the DALI connector.

If the built-in 250mA DALI power supply is required, wire between the ‘+’ and

‘Power Link’ terminals of the DALI connector to provide DALI power.

REMEMBER THAT YOU CANNOT EXCEED THE DALI POWER SUPPLY OF 250 mA.

4.3. Check Connections

Check that all the necessary connections have been made correctly and securely

Step 5 Replace Cover & Power Up the Unit

1. Replace the cover using the original screws. (Screw size = M4x6).

2. Power up the dimmer unit by switching on the MCBs.

3. Check that the display screen lights up and the dimmer channel levels appear.

Step 6 Set SDIM Addresses

If the dimmer is connected to a system through its SDIM connection terminal, the

SDIM addresses must be set as follows:

Display Procedure

Upon power up of the unit, the LCD

‘Display Screen’ appears.

Access Addresses Menu

From the Control Panel of the dimmer module:

1) Press on the keypad to access ‘Main Menu’.

2) In ‘Main Menu’, with the arrow pointing at

‘Addresses’,

press .

The ‘Addresses’ menu appears, listing

the addresses for S-DIM and DALI.

Set SDIM base address

1) At ‘Set SDIM base’, press .

2) Press or to select a base address

and press to enter.

3) Press to return to ‘Addresses’ menu.

Note: The base address is the first channel address,

from which the remaining addresses follow

consecutively (unless changed manually in the ‘SDIM

address’ sub-menu, see procedure below).

Set SDIM addresses (optional)

If you wish to set the addresses individually:

1) Press ‘down’ to select ‘SDIM addresses’ and press

2) Press or to select a channel and

press to enter.

3) Press or to select an address and

press to enter.

4) Press and hold to return to ‘Main Menu’.

The S-DIM addresses are now set and the unit is operational.
