a distance between contacts of at least 3mm for this unit.
The unit must be correctly grounded, and the supply line must be equipped with a suitable breaker and
RCD to protect people.
Disconnect all wires/cables before performing any maintenance or cleaning to reduce the risk of electri-
cal shock.
The unit is not explosion-proof, so it should not be installed in an explosive atmosphere.
Never touch electrical components immediately after the power supply has been turned o since the
system can still have residual energy, so an electric shock may occur. Therefore, after turning o the
power, always wait 5 minutes before touching electrical components.
This unit contains no user-serviceable parts. Always consult an authorised contractor for repairs.
