Use crimp terminals suitable for M3.5 screws that have the following dimension.
7 mm max.
Caution Tighten power supply terminal screws with a torque of 0.8 N-m. Not tightening
the screws securely may result in a fire or faulty operation.
Note 1. Be sure to use the same circuits when supplying power to the Power Supply
Units.
2. Check the settings for the power supply voltage switching terminals.
3. After the wiring has been completed, be sure to remove the top-surface la-
