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 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", 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/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 Adjust the fuse protection upstream of the transformer in the Auxiliary Power Supply
Module for a line infeed in the 380 to 480 V 3 AC voltage range.
(→ See the chapter titled "Cabinet Modules", section "Auxiliary Power Supply Module")
18 Where protection > IP21 is provided, the installed fan in the Line Connection Module
with option L43 must be supplied with 230 V AC from the auxiliary voltage busbar
system of the Motor Module.
(→ See the chapter titled "Options", section "Version L43 for Basic Line Modules")
19 The date of manufacture can be determined from the rating plates of the power
components 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 shorter than two years, the DC link capacitors do not have to be
reformed. If the downtime is longer than 2 years, the capacitors must be reformed as
described in the chapter titled "Maintenance and servicing", section "Reforming the DC
link capacitors" in this manual.
