Testing the Insulation Performance
Insulation Requirement
The impedance between the cabinet and ground must be larger than 5 Mohm.
Procedure
Step 1 Set the multimeter measurement mode to Mohm and measure the impedance
between the bolts and cabinet, as shown in Figure 4-211.
Figure 4-211 Insulation test
Step 2 View the impedance value on the multimeter.
If...
Then...
The measured impedance is greater
than or equal to 5 Mohm
The impedance is within the allowed
range and the insulation test is
complete.
The measured impedance is smaller
than 5 Mohm
Go to 3.
Step 3 Remove all the mounting accessories and check whether any insulation parts are
missing or damaged.
