Maintenance
The units require minimum maintenance, however to keep the units in good condition, the
following tasks should be carried out.
– Clean the units:
– Periodically clean the units with a damp, lint-free cloth.
– Clean the air inlets:
– The units can collect dust from the operation of the internal fans. The air inlets of the
units should therefore be cleaned on a yearly basis.
– Periodically check unit connections and grounding:
– To ensure that all cable connections to the units are secure.
– The ground (Protective Earth) connection of the system components.
Warning!
Dangerous mains voltages are present inside the units. Disconnect the main power supply
before doing any maintenance tasks.
