Signal connections
19 System operation by higher-level controller / control room. The control cables and
analog signal cables must be connected in accordance with the interface
assignment. Taking into account electrical interference and the distance from power
cables, the digital and analog signals must be routed with separate cables. The
shields of the shielded cables must be connected close to the cabinet entry point
through the largest possible surface area and with low
impedance on the shield support bar provided. The shield must be routed without
interruption up
to the cable connection point.
See Chapter Electrical Installation/ EMC-compliant design (Page 63)or Chapter
Electrical Installation/ Signal connections (Page 85)or
Electrical Installation/ Other connections (Page 91).
The cables must be identified uniquely and permanently with cable
numbers. The cable numbers must be documented on the terminal diagram.

Operating Instructions, 04/2015, A5E36161239/RS-AA/001
The 230 V auxiliary supply for the motor anti-condensation
heater (power type-specific) must be connected to terminals
-X4.5 .6 and must be protected in the low-voltage switchgear
with a max. 16 A fuse.
See description of options.
The 24 V auxiliary supply to supply power to the
electronics of the converter equipment is connected to termi-
nals -X2.51 .52 and must be protected with a max. 16 A
fuse with B or C characteristics. The load current is 1 A to
5 A depending on the number and types of the options used.
See description of options.
Note:
There is electrical separation according to the requirements
for protection against electric shock according to EN61800-5-
1 at all customer connections with input/output voltages in
the range up to 60 V DC (DVC A). This is the reason that
only components whose inputs/output voltages lie in this
range and which also have electrical separation can be con-
nected at these connections.
The cable to supply motor fan 1 must be connected to termi-
nals -X3.3 .4 .5 and to the connecting terminals in the motor
fan terminal box. Ensure the correct the sequence (do not
forget to check the direction of rotation during commission-
ing!).
The trip current of the motor circuit breaker =F1-Q11 must be
set as per the motor fan's type plate data and must be doc-
umented
in the circuit diagram.
The cable to supply motor fan 2 must be connected to termi-
nals -X3.6 .7 .8 and to the connecting terminals in the motor
fan's terminal box. Ensure the correct the sequence (do not
forget to check the direction of rotation during commission-
ing!).
The trip current of the motor circuit breaker =F1-Q2 must be
set as per the motor fan's type plate data
and must be documented in the circuit diagram.
