5.5 Voltage supply
5.5.1 Mains voltage
Danger due to electric current
•
It must be strictly observed that the line voltage complies with speci
fi
ed on the rating
plate and lies within the allowable tolerance speci
fi
cations (see technical data).
•
Between the voltage supply of the device and the protective earth
“
PE
”
is in no case a
higher voltage permissible than the indicated line voltage of the device!
•
Mains connection to: PE, L1 and N.
•
Attention!
–
To activate the on current limitation, you must wait at least 90 seconds after switch-
ing o
ff
the line voltage before switching back on!
5.5.2 Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the
de
fi
ned standard voltages in IEC 60038!
5.5.3 Line protection fuse
The connection must be fused depending on the used cable, the type of routing, the
operating conditions and according to the standards applicable on site. The speci
fi
cation
for the maximum admissible line fuse of the device must be observed (see technical
data).
Possible components for the line protection (recommendation):
•
Safety fuses of operating class
“
gG
”
(whole range fuse cartridges for general applica-
tions according to EN 60269-1).
•
Line protection switch with characteristic
“
C
”
(according to EN 60898-1).
5.5.4 Operating in IT-System
Danger due to electric current
•
In the IT-System the neutral point of voltage supply is not grounded; in the case of a
short-circuit between a phase (e.g.
“
L1
”
) and protective earth
“
PE
”
becomes the
protective earth potential = phase.
•
Between the connection of the voltage supply of the device and the protective earth
“
PE
”
is in no case a higher voltage permissible than the indicated line voltage of the
device!
