3.4 Auxiliary power/power requirements
The permissible tolerance of the specified mainsvoltage is + 5 % and - 10 %.
Greater deviations will impair functionality.
Only connect the machine to a three-phase AC mains with phases L1, L2 and
L3, otherwise the brake module or the frequency converter may be destroyed.
Operating the machine together with phase converters, frequency converters
or transformer-capacitor combinations will destroy the brake module or the fre-
quency converter and power supply unit!
Screw-in fuse links of the type NEOZED D02 (utilisation category gL) should
preferably be used as back-up fuses.
The supply line must be dimensioned such that it cannot be overloaded and a
max. voltage drop < 3% occurs at nominal current.
The loop impedance and suitability of the overcurrent protection device must
be inspected/tested at the machine installation site.
The following devices can be used:
Manufacturer: Doepke switching devices; these switching devices can also be
purchased via Altendorf.
• DFS4 040-4/0,30-B NK, release current 300 mA
• DFS4 040-4/0,03-B NK, for personal protection

Note!
Devices for differential protection (to be provided by the customer!)
In 230V400V systems, devices are generally used that detect leakage
currents < 300 mA. For switch-off in the event of a fault, RCDs (residual
current devices) with a rated differential current < 300 mA are normally
used, and for indication, fault current indicators (relays) or RCMs
(residual current monitors) are used.
Mains voltage independent devices for differential protection that also
detect differential currents (leakage currents) with DC components are to
be used.
If leakage current indicators or RCMs are used, ensure that additional
switch-off devices, e.g. circuit breakers, are provided.
(Extract from VDS Directive 2033)
If there are special safety requirements for persons setting up the equip-
ment, then frequency converters complying with EN 50178 must be
replaced by RCMAs with an isolator (preferably) or by type-B RCDs (uni-
versal-current-sensitive residual-current circuit breakers).
