The dimmer units are capable of handling up to :

• 5508D1D : 8 A across 8 dimmed channels (1 A per channel)

• 5504D2D : 8 A across 4 dimmed channels (2 A per channel)

• 5504DHD : 12 A across 4 channels (maximum of 5 A on any channel, maximum 6 A total on any 2 adjacent channels)

When installing the units:

• The dimmer unit requires mains power provided via the L/N/E connections at the top left, as well as power to the dimming banks (5508D1D /5504D2D) or dimmer channels (5504DHD) in order to operate the dimmer channels.

• All terminals on the dimmer unit are suitable for cable up to 4 mm² when using bare cable or 2 x 2.5 mm² if using ferrules.

• Make sure while terminating cables into the terminals, that no loose strands of copper fall into unit or enter any aperture other than the terminal.

• The terminals require a PH1 Phillips driver or a 0.8 x 4 flat blade screwdriver.

• Torque must not exceed 0.6 Nm when tightening terminal screws.

• Rubber bungs are supplied for unused RJ45 connectors, to stop foreign bodies from entering the unit. Always install these bungs when the unit is mounted inside a mains rated enclosure.

110 V Electrical Wiring

To use the dimmer with a 110 V unit supply, break the T-Block terminal using a screw driver and connect a wire link between terminals.

WARNING
EQUIPMENT DAMAGE HAZARD Do not break T-Block terminal and/or insert a wire link unless using the dimmer with 110 V unit supply voltage. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Phase Independence

The 5508D1D and 5504D2D have two separate Dimmer Banks which each require separate Active and Neutral connections.

On these variants, each Dimmer Bank may be connected to a different phase.

The 5504DHD High Power Dimmer has independent Active and Neutral connections per channel, meaning each channel may be connected to any phase.

On all models, the Unit Power Supply may be connected to any phase.
