To supply auxiliary equipment (e.g. separately-driven fan for
motor), the drive must be properly connected to terminals -X155:1
(L1) ... -X155:3 (L3). The supply voltage of the auxiliary
equipment must match the input voltage of the cabinet unit. The
load current must not exceed 10 A and must be set at -Q155 in
accordance with the load connected (see "Electrical installation /
Other connections / Connection for external auxiliary equipment
(option L19)").
The monitoring of the surge arresters and the upstream fuses
must be connected to terminal -X700 (see Chapter "Electrical
installation/Other connections/operation on an IT line supply
(option L21)").
In equipment with main circuit breaker, the release current must
be set to match the installation requirements (see "Electrical
Installation / Other connections / Main switch incl. fuses or main
circuit breaker (option L26)").
The 230 V auxiliary supply for the cabinet illumination with an
integrated service socket must be connected to terminal -X390
and protected with a fuse (max. 10 A) on the line side (see
"Electrical installation / Other connections / Cabinet illumination
with service socket (option L50)").
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 and protected with fuses (max. 16 A)
(see "Electrical installation / Other connections / Anti-
