4. Disconnect the power cable connector from the load current supply.
5. Screw the load power supply tight (torque 1.5 Nm).

Note
Load power supplies can only be mounted on the left or right side outside the S7-1500R/H
redundant 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.
