WARNING L
ETHAL ELECTRIC SHOCK
Deadly electrical voltage at the test probes for > 25 VAC voltage and > 60 VDC voltage!
Before servicing disconnect all affected devices from the power supply and secure (e.g.

with a sign) against unauthorised reconnection!

Maintenance intervals

Every 50,000 cycles
Part
Lubricate gas spring bearing
and check function
Note: the service life of the gas spring
is specified by the manufacturer as
50,000 cycles. In long-term tests,
however, the gas springs have
remained effective at several times
this specified life.
Every 3 months
Part
Check test adapter for wear
Annually
Part
Protective conductor wiring
(only available with corresponding
additional function)
7.2) Check and replace test probes
The spring-loaded test probes are subject to very different loads. A reliable signal transmission is
only possible with fully functional test probes. Conditions for reliable contact are:
 no contamination on the plunger tip
 no excessive wear of the points of the plunger tip
 no scratches on the test probe's plunger shaft
 no metal chips, particles, or other contamination on the probe plate between the probes
 test probe is installed securely in the receptacle
 no height differences between test probes of the same type
 no bending of the test probe
 correct position of the respective test probe types
The spring-loaded test probes can be removed and installed quickly without the need additional
wiring thanks to the receptacles. Specialised insertion and extract tools are available from INGUN
to replace test probes.

ter 7.5) Grease/lubricate test
adapter
Replace defective parts and
grease bearing of gas spring
Procedure
Clarify the cause and replace
defective parts, contact the
manufacturer if necessary

old: 0.3 Ω) Visual inspection;
if necessary, replace defec-
tive wiring
