WARNING
Fire hazard due to overheating when permissible cable lengths are exceeded
Excessively long cable lengths can cause components to overheat with the associated risk
of fire and smoke.
• The total cable length between an Active Interface Module and Active Line Module as
well as between an Active Interface Module and Basic Line Filter must not exceed 10 m.
NOTICE
Destruction of the Active Interface Module through incorrect settings made during
commissioning
The Active Interface Module can be destroyed through incorrect settings in the software.
• Do not use any SINAMICS firmware version less than V2.5.
• Operate Active Interface Modules only with the following settings in the commissioning
wizard:
– Set the "Line filter available" option for the Active Line Module.
– Select line filter "AIM 400 V ..kW (6SL3100-0BE..-.AB.)".
With firmware version SINAMICS V2.5, the default setting in STARTER/SCOUT is
"Wideband Line Filter". Switchover parameter p0220 to "AIM" (see SINAMICS
S120/S150 List Manual).
In conjunction with SINAMICS from V2.6 and higher, the appropriate Active Interface
Module is already preset by running the wizard in STARTER.
NOTICE
Destruction of the Active Interface Module through incorrect or missing wiring
The Active Interface Module can be destroyed through incorrect wiring or a missing 24 V
supply.
• Before commissioning the Active Interface Module, it is essential to connect the 24 V
DC at connector X124 to supply the fans.
• Connect the temperature signaling contact of the Active Interface Module to the
temperature input of the associated Active Line Module.
NOTICE
Damage caused by overheating as a result of an inadmissible mounting position
When incorrectly mounted, the Active Interface Module can overheat and therefore be
damaged.
• Only operate the Active Interface Module in a vertical position with the line connection at
the bottom.
