Stop!
The power supply module may only be operated on balanced mains
supplies. Operation on mains supplies with earthed phase is not
permitted.
The ECSxE series power supply modules are provided with an automatic
detection of the mains voltage and adapt the brake chopper switch−on voltage.
Please observe the restrictions for the respective supply forms:
Mains
With earthed
neutral
(TT/TN systems)
With isolated
neutral
(IT systems)

Operation of the power supply
modules
No restrictions
The ECSxExxxx4I IT variant can be
used if the power supply module is
protected in the event of an earth
fault in the mains supply:
by suitable equipment detecting
l
the earth fault.
by disconnecting the power supply
l
module immediately from the
mains.
Mains voltage dips can be reduced by decreasing the max.
charging current limit (C0022).
Deactivate the charging current limitation (charge relay) of the
connected ECS axis modules with C0175 = 3.
Notes
Observe the rated data of the power
supply modules.
In the event of an earth fault at the
output of the power supply module,
safe operation cannot be guaranteed.
