Item Activity Available /completed
10 If a voltage other than the auxiliary supply (3-phase 380 – 415 VAC) is used, a suitable
matching transformer is required (option Y75).
Ensure that the chosen taps are appropriate for the voltage present. With respect to the
phase sequence, make sure that fans rotate in the right direction.
11 The open-loop and closed-loop control systems are supplied with voltage (230 VAC 50/60
Hz) via terminals. Refer to the "Technical specifications" for the drives for details of current
consumption. If communication with the open-loop and closed-loop control system is to
be maintained even if the main voltage fails or the drive is to be switched on again auto‐
matically if the power fails, this voltage must originate from a secure network. Alternatively,
choose option L53 (UPS-supported power supply for the closed-loop control system).
12 Connection for
external auxili‐
ary equipment
(option L19)
To supply auxiliary equipment (e.g. separately-driven motor fan), the
drive must be properly connected to terminals ‑X155:1 (L1) to ‑X155:3
(L3). The supply voltage of the auxiliary equipment must match the input
voltage of the drive. The load current must not exceed 10 A and must
be set in accordance with the connected consumer.

13 Cabinet anti-
condensation
heating (option
L55)
If the drive is equipped with option L55 (cabinet anti-condensation heat‐
ing), provide the required auxiliary voltage (V) via the terminals. Protect
the auxiliary supply with fuses on the low-voltage distribution board side.
This voltage is not integrated in the EMERGENCY STOP sequence of
the drive and is, therefore, present even when the EMERGENCY STOP
button has been actuated. These cabinet-internal cables can be easily
identified by their orange insulation.
Provide for the service power sockets in the control cabinet as well as for the optional
cabinet lighting (option L50) on the auxiliary voltage supply
230 V). Protect the auxiliary voltage supply with 10 A fuses on the plant. This voltage is
not integrated in the EMERGENCY STOP sequence of the drive and is, therefore, present
even when the EMERGENCY STOP button has been actuated. These cabinet-internal
cables can be easily identified by their orange insulation.
To supply auxiliary equipment (e.g. separately-driven fan for motor), the drive must be
properly connected to terminals (L1) to (L3). The supply voltage of the auxiliary equipment
must match the input voltage. The voltage is supplied at terminals X ... Depending on
which option (option N30 to N33) is chosen, different circuit-breakers are available with
the assigned motor circuit-breaker. When connecting the power supply, take into account
the direction of rotation of the drive. Set the motor circuit-breaker so that it protects the
drive. Protect the auxiliary supply for the auxiliary equipment (e.g. separately-driven motor
fan) with fuses on the system side. The circuit-breaker is activated by means of the "Aux‐
iliary equipment ON" command from the drive controller.
13 Drive operation by higher-level controller / control room.
Connect the control lines as specified in the interface assignment. Connect the shield.
Route the digital and analog signals with separate cables to minimize interference. Ensure
that the required distance from the power cables is maintained.
Set selector switches S5.0 / S5.1 appropriately when the analog inputs on the customer
terminal strip are used as current or voltage inputs.
