Installation
Dimmer systems contain potentially hazardous voltages and high temperatures.
Installation should only be carried out by suitably qualified personnel, safe working
practices observed, and caution exercised at all times. Ensure that all Power supplies
are properly isolated before gaining access.
Location Any dimmer installation requires careful choice of location. Dimmers
should, if possible, be sited close to the lamp loads to minimise cable
runs. Although the design of Wallrack reduces the radiated noise
common to conventional dimmers, it is important to avoid siting in
acoustically 'live' positions in the performance area.
The incoming mains distribution should be sited as close to the racks as
practicable, and adequately fused isolators provided close to each rack.
Max rating 80A-3 phase, 160A-single phase(Wallrack 24x2.5kW).
Allow adequate clearance at the front of the dimmer rack, in order for it to
be opened for wiring to the load, supply and control terminals and allow
safe servicing of the equipment.
Ventilation
Adequate ventilation must be provided to maintain an ambient
temperature within the range 0 to 35 C and humidity of 45-95% non-
condensing. Special attention should be paid to the need to maintain
ambient temperature within these limits when Wallrack is enclosed in a
small room.
Do not obstruct the ventilation slots.
