Step 2 Check the insulation only after the upstream and downstream circuit breakers in
the PDC are switched o.
1. Switch o the upstream circuit breaker QFS for the SPD in the input module
of the PDC, and switch on other circuit breakers.
Figure 6-1 Switching o the SPD circuit breaker
2. Check that the insulation resistance between the live wires, between the live
wire and the PE, and between the live line and the neutral wire is no less than
0.5 megohm using a multimeter.
3. After checking, turn o all the circuit breakers.
Step 3 Switch on the SPD circuit breaker.
If the indicator of an SPD module is green, the SPD module is running properly. If
an indicator is red, the corresponding SPD module has failed and must be
promptly replaced.
Figure 6-2 Switching on the SPD circuit breaker
Step 4 Switch on the input power circuit breaker to power on the PDC. If the power
indicator on the front panel of the PDC lights up, the PDC is powered on properly.
The input power circuit breaker refers to the output circuit breaker that controls power
supply from the upstream power distribution equipment to the PDC.
Step 5 After the MDU screen starts, perform operations.
● If this is the initial startup, set the language, time, date, network parameters,
and system parameters by using the Setting Wizard.
