4.6 Power-on Check on an RHUB
This section describes the power-on check on the RHUB after the RHUB hardware is installed
and checked.
Context
DANGER
Power-on check involves high-voltage operation. Be cautious when conducting the power-on
check. Any direct contact with the input voltage or indirect contact through damp objects might
endanger your life.
Procedure
Step 1
Measure the RHUB earth resistance.
If... Then...
The RHUB earth resistance is less than
10 ohms Go to Step 2 .
The RHUB earth resistance is equal to or
larger than 10 ohms Find out the cause and ensure that the resistance
meets requirement. Then, go to
Step 2 .
Step 2 Measure the voltage of the RHUB.
If... Then...
The external power supply ranges from
100 V AC to 240 V AC Go to Step 3 .
The external power supply does not
range from 100 V AC to 240 V AC Find out the cause and ensure that the resistance
meets requirement. Then, go to
Step 3 .
