Safety pointers for the electrical connection
DANGER!
Connecting the service voltage.
Improper connection of the service voltage can be potentially fatal. The system may also be
damaged. Local regulations for electrical connection must be observed at all times.
Furthermore, the following basic principles must be observed:
▪
It is imperative that the protective conductor is connected.
▪
On systems with a service voltage of between 215 and 240 VAC, a back-up fuse with a
tripping current of 10 A must be present. The cables must be able to withstand this
load.
▪
On systems with a service voltage of between 110 and 120 VAC, a back-up fuse with a
tripping current of 20 A must be present. The cables must be able to withstand this
load.
▪
The mains cable must be able to withstand an ambient temperature of 70 °C.
▪
A residual current circuit breaker must be used. On systems equipped with a frequency
converter, a residual current circuit breaker that is sensitive to all currents (type B) must
be used.
▪
The system must not be charged with voltage until the installation is completed and all
covers are mounted.
▪
If faults cannot be remedied, the system must be put out of operation and protected
against inadvertent operation.
