6.9.2 Operation on special systems
TN­ and TT system
Caution
Operation is only permitted if:
● In the case of three­phase devices with external conductor voltages 3x
230 V AC, 3x 400 V AC, 3x 480 V AC the star point of the supply system
is earthed and the supply system conforms to the maximum overvoltage
category III as per EN 61800­5­1 at a system voltage (external conduc­
tor → star point) of maximum 277 V.
● At external conductor voltages 3x 230 V AC, 3x 400 V AC, 3x 480 V AC
● The star point of the supply system is earthed
● The supply system conforms to the maximum overvoltage category III as
per EN 61800­5­1 at a system voltage (external conductor ­> star point)
of maximum 277 V.
IT system
Caution
Operation is not permitted!
In case of an earth fault the electrical stress is approx. twice as high. Clear­
ances and creepages to EN 61800­5­1 are no longer maintained. The de­
vice may be destroyed in the process.
6.10 AC mains connection 24 V switched­mode power supply
Connection internal switched­mode power supply X01B (Line IN
Aux)
The mains connection on Line IN Aux supplies the integrated 24 V switched­
mode power supply. This 24 V DC supplies the entire system via busbars.
For compliance with device safety as per EN61800­5­1 please use mains
fuses of utilisation class gG that disconnect the device from the mains in the
event of a fault.
