Commissioning Third-Party Equipments; Main Circuit Breaker (Mcb); Power Cables - ABB ACS580MV Commissioning Manual

24 Standard Commissioning Process
NOTICE For later tests, motor and driven equipment is recommended to be uncoupled.

Commissioning third-party equipments

If third party equipment has to be commissioned by an ABB commissioning engineer, the
scope of the work involved and the responsibilities must be agreed by contract and the
commissioning engineer must be informed accordingly.
If the equipment mentioned in the following sections is not commissioned by an ABB
commissioning engineer, confirmation that the equipment has been tested and is ready for
operation must be obtained from the responsible person.
In DriveStartup: It is necessary that the steps are reviewed when checking third-party
equipment and that each item is checked off before the commissioning has been
completed.

Main circuit breaker (MCB)


The main circuit breaker is commissioned and the insulation tests are performed according
to the manufacturer's documentation.
The signed MCB commissioning report must be received from the responsible person.
The correct operation of the MCB will be tested before the MCB is used to supply the main
power to the converter. The test is performed with the MCB in test position.
Information on the required control interface to the converter and on the breaking time of
the circuit breaker can be obtained from the
(2UBB013672) and the converter wiring diagrams.
The following has to be checked:
•
It is forbidden to set common point for open status, close status and ready status
signals.
•
The MCB must open once the auxiliary power is removed. If the MCB is equipped with
under voltage trip coil.
•
The MCB is commissioned and the insulation tests are performed according to the
documentation of the manufacturer (The signed MCB commissioning report must be
received from the responsible person).

Power cables


The insulation resistance must be measured or the confirmation of the measurement must
be obtained.
In case measurement has to be performed by the service engineer, please refer to
Cables Insulation Test.
NOTICE The field engineer should confirm that the power cables are connected to the
correct bus bars before switching on the main power. Once the main power direct reach
the output bus bars by wrong connections, the power modules would be irreversible
damaged.
