Insulation Test - Reznor EFMA Installation Manual

2.2 Insulation Test

For the warranty to be valid, fill out the measures' table and ensure that the
10 readings have been correctly noted.
A qualified electrician must measure the system's insulation resistance as follows:
• Use a calibrated megohmeter only;
• Measure insulation resistance at the free end of the cold lead, between the phase
conductor and ground;
Fig. 2.2
• Write the reading in the measures' table;
• This reading must be over 1,000,000 ohms;
• If the reading is under 1,000,000 ohms, stop work and contact REZNOR's technical
