7. Routine maintenance

The following simple maintenance procedures are recommended to keep your
Smartrack installation in perfect working order throughout its life.

7.1. Torque settings

Following first installation, and at regular intervals in situations where dimmers
are subjected to vibration, we strongly recommend that all terminal screw torque
settings be checked for tightness, using the torque setting table below:
Power Terminal hex-headed screws
RCD and Circuit breaker terminals
Earth and neutral terminals – 10mm
Earth and neutral terminals – 2.5mm
2.5kW load terminals
5kW load terminals
10kW load terminals
To retorque terminals, open the front door of the rack, by releasing the three cap-
tive screws on the front panel, and use a torque setting screwdriver. Note that all
terminal screwheads face forwards, for ease of access.

7.2. Cleaning

In average conditions of use, cleaning should be carried out on an annual basis.
a) Using a vacuum cleaner with a soft furniture nozzle, clean the outside of the
Smartrack enclosure. Then use a damp or spirit-soaked rag to remove grease
or stains.
b) Switch off supply power and open the rack. Using an air blower, blow dust
out of the electronics, behind the aluminium protective cover.
