installation protection
(con’t)
Differential circuit breaker
In case of insulation defect, for personnel protection you must install
on the main power supply a type B differential circuit breaker GFI
(or RCD) of 300 mA. This equipment protection device is compatible
with type T.T electrical network.
For other network type T.N or I.T, apply the right protection device.
Contact Adixen product manufacturer for advice.
In all cases, comply with current local regulations.
Ensure that the equipment and the electrical supply cable are suitably
protected against earth defects and that the earth wire is longer than
the three conducting wires.
The user must provide a second protective earth (ground) conductor
with a cross-sectional area at least equal to the conducting wire size.
Than, connect the protective earth stud to the suitable installation earth
point.
An IEC 417#5019
symbol is located
on the rear panel
for the main power supply
earth terminal.
