16 Option L21
Surge suppres-
sion
The monitoring of the surge arresters and the upstream fuses
must be connected to terminal -X700 (see "Electrical installation /
other connections / overvoltage limitation (option L21)").
Point 9 must also be observed:
"Before the drive is operated on a non-grounded line supply (IT
system), the connecting clip to the basic interference suppression
module must be removed" (see "Electrical installation/Power
connections/Removing the connection clip to the basic interfer-
ence suppression module for operation on non-grounded line
supplies (IT systems)").
17 Option L50
Cabinet lighting
with service
socket
The 230 V auxiliary supply for the cabinet lighting with an inte-
grated service socket must be connected to terminal -X390 and
protected with a fuse (max. 10 A) on site (see "Electrical installa-
tion / Other connections / Cabinet lighting with service socket
(option L50)").
18 Option L55
Cabinet anti-
condensation
heating
The 230 V auxiliary supply for the anti-condensation heating for
the cabinet (230 V / 50 Hz, 100 W / or 230 V / 50 Hz 2 x 100 W
for cabinets with a width of 800 ... 1200 mm) must be connected
to terminals -X240: 1 to 3 connected and protected with fuses
(max. 16 A) (see "Electrical installation/Other connec-
tions/Cabinet anti-condensation heater (option L55)").
19 Option K74
Auxiliary power
supply,
230 V AC
The voltage of the auxiliary power supply (-T10) must be adapted
to the supply voltage of the cabinet unit (see "Electrical installa-
tion/additional connections/auxiliary power supply, 230 VAC
(option K74)").
Signal connections
20 Cabinet unit operation by higher-level controller / control room. The control cables
must be connected in accordance with the interface assignment and the shield ap-
plied. Taking into account electrical interference and the distance from power ca-
bles, the digital and analog signals must be routed with separate cables.
21 Option G60
TM31 customer
terminal block
The TM31 Terminal Module is used to extend the customer ter-
minals.
This provides the following additional interfaces:
• 8 digital inputs
• 4 bidirectional digital inputs/outputs
• 2 relay outputs with changeover contact
• 2 analog inputs
• 2 analog outputs
• 1 temperature sensor input (KTY84-130/PTC)
Integration of the interfaces takes place via pre-interconnections
prepared in the factory, which can be selected during commis-
sioning.
When the analog inputs on the TM31 are used as current or volt-
age inputs, selectors S5.0 and S5.1 must be set accordingly (see
"Electrical installation / Signal connections / Customer Terminal
Module (-A60)").
