Checking of operation of the insulation monitoring
A
Check insulation daily with operating
machine and switched on connection
sockets.
- Turn on the electrical equipment with
switch (1), control light (2) comes on.
- Press testing button (3) and the in-
scription „Isolationsfehler - Insulation
Fault“ shall come on.
- Depress the button clear (4) and the
insulation fault inscription will go dark.
f If the test is completed successfully,
work can proceed with the electrical sys-
tem and external consumers can be
used.
If the „Insulation Fault“ control light indi-
cates a fault already before pressing the
control button, then work cannot pro-
ceed with the electrical system and the
external consumers. In case of insula-
tion fault the connection sockets are au-
tomatically turned off.
Work with the electric system cannot proceed if the simulation does not indicate a fail-
ure.
f In case of failures, the electric equipment needs to be tested and repaired by an elec-
trician. With these devices and the equipment work can be resumed only after such
test and repair.

ried out by an electrician!
