It is only permissible to establish connections to the DC link using the adapters that

SIEMENS has recommended (DC link adapter and DC link rectifier adapter).

The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30 %) must be

checked before commissioning is carried out when the system is disconnected from the

power supply and the DC link is discharged. The screws must be tightened after

transportation.

The DC link side covers are supplied as standard with the components; they can also be

ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).

Only Siemens cables should be used for DRIVE-CLiQ connections.

If a drive line-up is switched off by means of the line disconnecting device, the voltage at

terminals 3 (EP +24 V) and 4 (EP M) must be interrupted beforehand. This can be achieved

through e.g. an auxiliary contact.
