■
European Union and United Kingdom
To comply with European Union directives and United Kingdom regulations related
to standard EN 60204-1, the disconnecting device must be one of these types:
•
switch-disconnector of utilization category AC-23B (IEC 60947-3)
•
disconnector that has an auxiliary contact that in all cases causes switching
devices to break the load circuit before the opening of the main contacts of
the disconnector (EN 60947-3)
•
circuit-breaker suitable for isolation in accordance with IEC 60947-2.
■
North America
Installations must be compliant with NFPA 70 (NEC)
1)
and/or Canadian Electrical
Code (CE) along with state and local codes for your location and application.
1)
National Fire Protection Association 70 (National Electric Code).
■
Other regions
The disconnecting device must conform to the applicable local safety regulations.
Implementing a fast switch over between the power line and
generator
You can do a fast switch over between the power line and generator without
stopping the drive. Starting and stopping the drive takes more time than the fast
switch over.
WARNING! The drive requires at least a 50 ms fast switch over time and the
same phase order in the switching. A shorter switch over time or a different
phase order can cause a drive fault trip or damage to the drive.
Consult ABB for implementation instructions of the fast switch over system.
Selecting the main contactor
You can equip the drive with a main contactor.
Follow these guidelines when you select a customer-defined main contactor:
•
Dimension the contactor according to the nominal voltage and current of the
drive. Also consider the environmental conditions such as surrounding air
temperature.
•
IEC devices only: Select contactor with utilization category AC-1 (number of
operations under load) according to IEC 60947-4.
•
Consider the application life time requirements.
