2.2 Insulation Test
Measure EFMA’s insulation resistance at each step using a megohmeter (Fig.
2.2) and record readings on the measures’ table (this label is available at the
opening of the product).
IMPORTANT!
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;
