The torque for tightening the supply voltage terminal block on the device is
4.5 lb-in (0.51 Nm).
2.4.1
Supply voltage
In devices with two voltage inputs, the supply voltage can be connected
redundantly. Both inputs are uncoupled. There is no distributed load. The
supply voltage is electrically isolated from the housing.
Note:
With non-redundant supply of the mains voltage, the device reports a
power failure. You can avoid this message by changing the configuration in
the management, or, with power supply units of the same type, by feeding
the supply voltage in through both inputs.
