Installation
17.4 Connecting the connecting bars
ATTENTION
Risk of property damage
The connecting bars must be shaped and positioned so that they are perfectly adapted to
the rear sockets before tightening using bolts.
The connecting bars must be resting on a support attached to the electrical distribution
board, not directly on the rear sockets.
If a short circuit occurs, the deformation of the connecting bars must not damage the
fastening of the rear connections. To guarantee this, one of the connecting bar supports
should be used at maximum distance, according to the short-circuit currents as indicated
below:
