PIP- Protective Earth Resistance Test
To perform the Protective Earth Resistance Test in accordance with IEC 62353:
1. Ensure the Safety Analyzer set to the IEC 62353
standard.
Note:
Consult your safety analyzer user manual to
perform a “Lead Zeroing” operation to eliminate
test lead resistance from your measurements.
2. Set the Safety Analyzer controls to measure Ohms
by selecting the Ohm button on the Safety
Analyzer.
3. Establish the setup as shown in Figure 1.30a.
Note:
Ensure all connectors and connection points
are clean and are firmly attached. If not, you will
see higher readings from the safety analyzer.
4. Measure the resistance of AC power cord
ground
conductor
per figure 1.30a. Record the resistance
value on the PIP checklist. The measured value
must be below 0.1 ohms.
