4.4.1 Installing Diesel Air Breaker Assemblies

Diesel air breaker assemblies include diesel air breaker and air breaker interlock
device. When the power is supplied through a diesel, you need to install air breakers,
air breaker interlock device, and auxiliary internal connection cables on site.
Note:
The air breaker interlock device is designed to ensure that either of the two air breakers
is opened in any case.
To mount the diesel air breaker assemblies, proceed as follows:
