ATTENTION:
The input lines to the UPS must be fuse protected. The use of residual current switches in the line sup-
plying the UPS is not recommended. The leakage current due to the RFI filters is rather high and it can
cause spurious tripping of the protection device.
If any residual-current-switch has to be used, it is recommended the use of a device with short-time
delay for differential currents higher than 300mA.
The following table represents a summary about the current carrying capacity acc. DIN VDE- and EN-rules at an envi-
ronmental temperature of 30°C.
The necessary diameters of cable and the sizes of the fuses are to be designed with regard to the environmental tem-
perature, the cable grouping and length of cables according to the local rules and according to VDE.
The given values of cable diameters do not reflect the required diameters of the protective earth cable! They have to be
calculated in accordance to VDE 0100 part 540 or an applicable local rule.

WARNING:
The UPS requires the neutral of the bypass input only. When using the neutral of the main input too,
both neutrals have to be connected together.

Note.: L1-L3 and N = Hole for screw M8. PE Terminal: Bolt M10
ATTENTION:
For ensuring the selectivity all fuses should have the utilization category “gL”. In this case selectivity is
existent for fuses up to 16AgL. When using higher fuse ratings or automatic cutout a selectivity calcula-
tion must be carried out according to the local requirements. For the battery fuses a suitable breaking
capability must be ensured.
