Table 4-7 lists the checking items for other cable connections.
Table 4-7 Checklist for other cable connections
No. Item
1 The connectors of the other cables must securely connected.
2 Labels on the cables are legible and bound based on the engineering requirements.
The cables must be bound tightly and neatly. The sheaths of the cables must not
be damaged.
3 Positions for routing the cables must meet requirements of the engineering design.
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.
