2.3.1
Electric current
DANGER!
Danger to life due to electric power!
There is an immediate risk of fatal electric shock if
live components are touched. Damage to the insula-
tion of the individual components can be fatal.
– Have all work on the electrical equipment per-
formed by skilled electricians.
– In the event of damage to the insulation, cut off
the power supply immediately and initiate
repairs.
– Before working on live components of electrical
systems and equipment, de-energise these
components and secure them in this state for
the duration of the work. Adhere to the following
safety rules in this regard:
– Disconnect.
– Secure against restart.
– Verify that components have been de-ener-
gised.
– Ground and short-circuit.
– Cover or shield any adjacent live compo-
nents.
– Never bypass or disable any fuses. Comply with
the correct amperage specification when
replacing fuses.
– Keep moisture away from all live components.
This may lead to short circuits.
2.3.2
High temperatures
WARNING!
Danger of injury due to hot surfaces!
Surfaces on components may become very hot
during operation. Contact between the skin and hot
surfaces can cause severe burns to the skin.
– When working near hot surfaces, always wear
heatproof protective clothing and protective
gloves.
– Before opening the controller box, ensure that all
surfaces have cooled down to ambient tempera-
ture.
