Redundant power supply modules Q63RP and Q64RP
When power is switched on again immediately (within 5 seconds) after power-off, an inrush current of more than
the specified value (2 ms or less) may flow.
Reapply power 5 or more seconds after power-off.
When selecting a fuse and breaker in the external circuit, take account of the blowout, detection characteristics
etc.
Overcurrent protection
The overcurrent protection device shuts off the 5 V, 24 V DC circuit and stops the system if the current flowing in
the circuit exceeds the specified value.
The LED of the power supply module turns off or turns on in dim green when voltage is lowered. If this device is
activated, switch the input power supply off and eliminate the cause such as insufficient current capacity or short.
Then, a few minutes later, switch it on to restart the system.
Overvoltage protection
The overvoltage protection device shuts off the 5 VDC circuit and stops the system if a voltage of 5.5 V DC is
applied to the circuit.
When this device is activated, the power supply module LED turns on in red. If this happens, switch the input
power off, then a few minutes later on. This causes the initial start for the system to take place. The power supply
module must be changed if the system is not booted and the LED remains red.
