3. Open the front cover.
4. Disconnect the power cable connector from the load current supply.
5. Tighten the screw for the load current supply (torque 1.5 Nm).
6. Insert the already wired-up power cable connector into the load current supply.

Note
Load current supplies can only be mounted on left or right side outside the S7-1500
automation system / ET 200MP distributed I/O system. If you mount a load current supply on
the right of the configured setup, the heat development of the load current supply may make
a gap to the configured setup necessary. For additional information, refer to the relevant
manuals. The number of load current supplies that can be used is unlimited.
