Read the following carefully after power supply
1.
In a PDU with surge protection module, there are 3 seperate indicators:
A: Red light: When active, means the absence of earth wire of the power supply
system, which shall be the case to contact an electrician for a professional
check and grounding.
B: Yellow light: When active, means that wire L and null wire N are not in the
correct position. Which shall be the case to contact an electrician for a
professional check and re-arrangement of such lines.
C: Green light: When not active, means the failure of the lightning protection
circuit.
2.
PDU with hot swap surge protection module:
When the green LED indicator is active, the surge protection function of the unit
is normal. If not, then the unit is not functional. In the case of a non-functional
surge protection module, it has to be replaced with a new one. Once replaced,
the surge protection will then be restored.
3.
PDU equipped with a fast-fused protection system
When a fuse is blown out without power output, disconnect the connected
equipment from the power supply. Turn the screw on the over-load protective
device in an Anti-clockwise direction and remove the fuse. Put a new fuse in the
protective device and turn the screw in a clockwise direction. A tight securing of
the screw ensures a normal operation.
4.
PDU with minimum circuit breaker:
When the minimum circuit breaker cuts off the circuit loop, please switch off the
power supply. After fixing the issue, switch on the circuit breaker and then
connect the power supply.
