Planning the electrical installation

What this chapter contains

This chapter contains the instructions that you must follow when selecting the
cables, protections, cable routing and way of operation for the regen supply module.
If the recommendations given by ABB are not followed, the regen supply module
may experience problems that the warranty does not cover.
Note: The installation must always be designed and made according to applicable
local laws and regulations. ABB does not assume any liability whatsoever for any
installation which breaches the local laws and/or other regulations.

Compatibility

ACSM1-04 drives

The ACSM1-204 regen supply module, with an WFU-xx regen filter module of
appropriate size, is compatible with ACSM1-04 drives (frame sizes A...D).
Note: The ACSM1-204 regen supply module is not designed to be started under
load. If the DC bus is loaded when the ACSM1-204 tries to start, the start attempt
may fail.

Other drive types

The ACSM1-204 regen supply module and WFU-xx regen filter module do not
include a charging device capable of providing the initial charging of the drive or
inverter modules connected to the DC bus. Depending on the drive type, external
charging may be required.
WARNING! Without initial charging, the ACSM1-204 regen supply module, WFU-xx
regen filter module and other devices connected are permanently damaged when
the main contactor is closed.
Consider the following if a drive type other than the ACSM1-04 is used:
• Check that all the devices that are connected to the DC bus fed by ACSM1-204
regen supply modules can be charged through the DC bus without any external
charging device.
• If not, charge the drive externally before connecting it to the DC bus of the
ACSM1-204 regen supply module.
