Item Action
9 When connecting the braking resistor, the maximum permissible cable lengths be-
tween the braking module (options L61/L62, L64/L65) and the associated braking
resistor must be observed.
The resistor is connected directly to terminal -X5.
The thermal contact of the braking resistor must be wired up and its signal evaluated
by the controller.
(→ See Chapter "Options", Section "L61/L62, L64/L65, braking units")
10 With a parallel connection of Motor Modules in chassis format and connection to a
motor with a single-winding system, it is essential either to observe the specified min-
imum cable lengths or to install a motor reactor (option L08).
(→ See Chapter "Cabinet Modules", Section "Motor Modules in chassis format")
11 The DC coupling – including the pre-charging circuit of the associated DC-link capaci-
tance (option L37) – must be connected properly and all the fuses must be checked to
ensure that they are secure.
The digital signal for pulse inhibit must be properly wired and configured.
(→ See Chapter "Options" under "L37, "DC interface including pre-charging circuit of
the associated DC-link capacitance", Section "Commissioning the DC interface")
12 The cable shields must be properly applied.
13 The circuit breaker's tripping current must be set in accordance with the specific plant
conditions.
(→ See Chapter "Cabinet Modules", Section "Line Connection Modules")
14 The correct operating voltage must be set for the 230 V AC fans in the Line Connec-
tion Module, Basic Line Module, Smart Line Module, Active Line Module, and Motor
Module in chassis format.
Fine tuning to the relevant line voltage is performed by reconnecting the transformer
taps.
(→ See Chapter "Electrical installation", Section "Adjusting the fan voltage")
15 The correct internal power supply must be set in the Line Connection Module and the
auxiliary power supply module.
Fine tuning to the relevant line voltage is performed by reconnecting the transformer
taps.
(→ See Chapter "Cabinet Modules", Section "Line Connection Modules")
(→ See Chapter "Cabinet Modules", Section "Auxiliary power supply module")
16 Adapt the fuse protection for the transformer in the Auxiliary Power Supply Module for
a line supply voltage in the 380 to 480 V 3 ph. AC voltage range.
(→ See Chapter "Cabinet Modules", Section "Auxiliary power supply module")
17 When the degree of protection is increased > IP21, the installed fan in the Line Con-
nection Module with option L43 must be supplied with 230 V AC from the auxiliary
power module of the Motor Module.
(→ SeeChapter "Options", Section "L43, Line Connection Modules for Basic Line Mod-
ules")
18 The date of manufacture can be determined from the rating plates of the power com-
ponents in the "Basic Line Module", "Smart Line Module", "Active Line Module", "Motor
Module in Chassis Format", and "Booksize Cabinet Kit" Cabinet Modules. If the period
from the date of manufacture to initial commissioning or the downtime of the power
components is less than 2 years, the DC-link capacitors do not have to be reformed. If
the unit has not been operational for more than 2 years, the DC-link capacitors must
be reformed as described in Chapter "Maintenance and servicing", Section "Forming
the DC-link capacitors".
