5.4.4 Grounding with isolation monitor
In machines equipped with an insulation monitor, connection of the grounding terminal (1) to a grounding
system is not required.
Located on the front of the machine, the isolation monitor continuously monitors the ground insulation of the
active parts.
If the isolation resistance drops below the set fault value, the isolation monitor interrupts the power supply to
the connected equipment.
It is important that the power cables of the equipment are equipped with the protective conductor (yel-
low-green cable) so as to ensure the equipotential connection between all the masses of the equipment and
the mass of the machine.
This provision is not valid for double insulated or reinforced insulated equipment.
Note:
You can connect the grounding terminal (1) to your own grounding system.
In this case, an IT-type system is created, that is, with the active parts isolated from the ground and the
ground plane earthed.
In this case, the isolation monitor controls the isolation resistance of the active parts both towards ground
and towards earth (for example, ground insulation of the power cables).
5.5 Electrical connections
*
Important
•
Connection to the systems must be carried out by a qualified electrician, who must perform the con
-
nection according to the regulations in force at the place of installation.
The electrical connection to the user system is one of the most important operations to be carried out before
use.
The safety and efficiency of the generating set and the user system itself depend on the correct connection.
Before powering the user system, perform the following checks.
1 - The connection cables between the generating set and the user system must comply with the rated volt-
ages of the system.
2 - The type of cable, section and length must be sized according to the environmental conditions of installa-
tion and local regulations.
3 -
The earth connection must be efficient to allow correct operation of the differential protection device.
4 - The cyclical direction of the phases must correspond to the needs of the user system. Do not connect the
phases to the neutral.
