Work on electrical equipment must be carried out exclusively by
electricians.
When performing any work on electrical components, the five
safety rules must be adhered to:
– Disconnect from the electrical supply
– Safeguard to prevent a restart
– Test to ensure a de-energised state
– Earth and short-circuit
– Cover or isolate adjacent live parts
Perform regular checks for insulation and housing damage.
Never operate the ELDRO
that are faulty or not ready for operation.
If there are power supply faults, the system must be switched off
immediately.
Before any work on electrical components, switch the mains
disconnection thruster off and secure it to prevent it being switched
on again.
It is essential to observe the inspection and maintenance intervals
specified by the manufacturer for electrical components.
All touchable, conductive parts of the system are connected to the
external earthing conductor system. The earthing conductor
system must be inspected after performing maintenance work (e.g.
replacing components).
Some equipment (e.g. mains power units, servo controllers,
converters) with electrical intermediate circuits may store residual
voltage for a certain time after being disconnected. Before starting
work on these systems, check that they are de-energised.
