Load connection

The following figure shows the two fundamentally possible arrangements for the connected
load. It can be connected at the top or bottom.

6.2.3

Arrangement of the power supply systems

Since both the 3KC4 and the 3KC8 have a flat connector, they can be connected to the
power supply system using cable lugs or busbars.
Transfer switching equipment of 2000 A and higher is connected using the optionally
available copper bar connection kit.
Note
The transfer switching equipment for 2000 A and higher comprises 2 switches (switch 1 and
switch 2) in each case. These must be bridged using the copper bar connection kit.
NOTICE
Incorrect connection in the case of network/generator applications of the 3KC8 transfer
switching equipment
The main current source must be connected to switch 1. Only then is the transfer switching
equipment functional. Connection of the generator to switch 2 is absolutely necessary for
controlling the generator.
