The test adapter can remain connected to

the system or the mains during the course of

all measurements, assuming absence of

voltage during the insulation resistance mea-

surement.

NOTE!

The fuses have to be checked before

each measurement. Blown fuses

must be replaced with new ones (see

“Fuse Replacement” on page 15).

4.1 Measuring Insulation Resistance

ISO)

ATTENTION!

Single-Phase Mains Connection

The phase must be connected to L1

for single-phase mains connection.

➭ Make sure that the system remains volt-

age-free for the entire duration of the

measurement.

ATTENTION!

Insulation resistance can only be

measured at voltage-free systems.

ATTENTION!

The N and PE conductors must be

disconnected at all times. Consum-

ing devices should not be con-

nected.
