4.2 Electrical installation: Checklist
Item Activity
10 When connecting the braking resistor, the maximum permissible cable lengths
between the Braking Module (options L61/L62, L64/L65) and the associated braking
resistor must be observed.
The resistor is connected at terminals R1 and R2 on the Braking Module.
The thermal contact of the braking resistor must be wired up and its signal evaluated
by the controller.
(→ See the chapter titled "Options", section "L61/L62, L64/L65, braking units")
11 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
minimum cable lengths or to install a motor reactor (option L08).
(→ See the chapter titled "Cabinet Modules", section "Motor Modules in chassis
format")
12 The DC coupling – including the pre-charging circuit of the associated DC link
capacitance (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 parameterized.
(→ See the chapter titled "Options" under "L37, "DC interface including pre-charging
circuit of the associated DC link capacitance" in section "Commissioning the DC
interface")
13 The cable shields must be properly applied.
14 The circuit breaker's tripping current must be set in accordance with the specific plant
conditions.
(→ See the chapter titled "Cabinet Modules", section "Line Connection Modules")
15 The correct operating voltage must be set for the 230 V AC fans in the Line
Connection 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 the chapter titled "Electrical installation" in section "Adjusting the fan voltage")
16 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 the chapter titled "Cabinet Modules", section "Line Connection Modules")
(→ See the chapter titled "Cabinet Modules", section "Auxiliary Power Supply Module")
17 Adapt the fuse protection for the transformer in the Auxiliary Power Supply Module for
a line supply voltage in the 3 AC 380 to 480 V voltage range.
(→ See the chapter titled "Cabinet Modules", section "Auxiliary Power Supply Module")
18 When the degree of protection is increased > IP21, the installed fan in the Line
Connection Module with option L43 must be supplied with 230 V AC from the auxiliary
power module of the Motor Module.
(→ See the chapter titled "Options", Section "L43 Line Connection Modules for Basic
Line Modules")
