5. Do not use wire end ferrules for the control terminals. The terminals are designed
so that the wires can be inserted in the terminals after twisting the individual
wires.

Mains Power Connection
The frequency inverters are designed for installation in a switchgear cabinet and for
permanent connection.
To guarantee lasting operating safety and reliability, the inverter must be connected expert-
ly in accordance with the valid electrical standards. Attention must be paid to good insula-
tion from earth potential on the power terminals.
An AC system with a nominal voltage of 230 V (50/60 Hz) must be connected to mains ter-
minals L1, N and PE or a three-phase system with a nominal voltage of 400 V (50/60 Hz)
to terminals L1, L2, L3 and PE (pay attention to rating plate). The neutral point must be
earthed (TN-C system).
Ensure a voltage balanced to earth or phase to phase when feeding in the mains power
through an isolating transformer (star point must be earthed).
The single exception below permits connection of a frequency inverter via a residual-cur-
rent-operated circuit-breaker as the sole protective measure:
•
Installation of a residual-current-operated circuit-breaker of the newest design for fre-
quency inverters up to 4 kVA (input voltage 1
×
230 V) with MOBILE connection.
This residual current-operated circuit breaker must be suitable for alternating and pul-
sating DC leakage current. Residual-current-operated circuit-breakers of this type bear
the symbol
.
Reliable tripping of the residual-current-operated circuit-breaker is not ensured in
the case of frequency inverters up to 4 kVA (input voltage 3
×
400 V) with MOBILE
connection; an additional protective measure must be used for this reason. Also see
the diagram below.
In the case of frequency inverters with PERMANENT connection (input voltage 1
×
230 V and 3
×
400 V), another protective measure must always be used in addition to
the residual-current-operated protective device. Also see the diagram below.
The protective function of the residual-current-operated circuit-breaker is no longer ensured
due to leakage currents from interference suppression capacitors in the inverter and DC
components in the fault current. All devices connected to this residual-current-operated cir-
cuit-breaker (and persons touching them) are no longer protected in the event of a fault.
Frequency inverters must not be connected via a residual-current-
operated circuit-breaker as the sole protective measure!
