Fuses
The pre-charging input circuit components are protected against overload using fuses.
The following fuses are recommended:
• For versions with one precharging resistor for each phase, 3NE1 817-0 (50 A) fuses are
recommended.
• For versions with two precharging resistors connected in parallel for each phase,
3NE1 021-0 fuses (100 A) are recommended.
• For versions with three precharging resistors connected in parallel for each phase,
3NE1 021-0 fuses (100 A) are recommended.
Main contactor
A contactor or a circuit breaker is used as main contactor. This is used to connect the Active
Interface Modules Chassis-2 to the line supply.
The following components are recommended.

It is only permissible that the switches are CLOSED and OPENED by the sequence control. An interlocking set 3WL9111-
1)
0BA21-0AA0, as described in Catalog LV 10, is recommended for the circuit breakers in order to exclude the risk of unin-
tentional manual operation. Manual operation bypasses the pre-charging circuit and can therefore destroy the Active
Line Module.
The main contactor is controlled via terminal -X9: HS1, HS2 of the Active Line Modules
Chassis-2. The switching capacity of the floating relay contact is described here: X9 terminal
strip (Page 227).
An additional normally open contact (NO contact) of the main contactor must be routed to
terminal -X47:3 to guarantee the feedback signal. The 24 V DC supply can be taken from
terminal strip -X42.
