Maintenance – Calibration
11.1
Housing Maintenance
No special maintenance is required. Keep outside surfaces clean and dry. Use a slightly
dampened cloth for cleaning. Avoid the use of solvents, cleansers and abrasives.
dampened cloth for cleaning. Avoid the use of solvents, cleansers and abrasives.
Note!
If the test case has not been used for a long period of time, the switches may
demonstrate increased contact resistance depending upon storage conditions.
If this is the case, actuate the switches several times.

11.2
Calibration
According to DIN VDE 0701-0702, measuring instruments used for periodic testing must be
tested and calibrated in accordance with the manufacturer’s specifications on a regular
basis. Depending upon usage, the manufacturer recommends an interval of 1 to 3 years for
this test instrument.

Periodic Self-Test of the Connector Cable for Protective Conductor Continuity
Connect the probe cable (21) to a grounding contact which has been previously tested for
absence of voltage (e.g. at an electrical outlet), and which is connected to the protective
conductor in the connector cable, and set the NETZ-VDE switch (1) to “NETZ”. Then
measure protective conductor resistance as described in section 5.4. If an excessively high
protective conductor resistance value is displayed at the LCD panel or if overloading is
indicated (only “O.L” appears), protective conductor resistance is too high or the protective
conductor is interrupted. Eliminate the interruption (in the cable or at the NETZ-VDE switch).

11.4
Testing the Integrated RCD (residual current circuit breaker)
Test on a regular basis. The integrated RCD (residual current circuit breaker) can be tested
by pressing the test key. Breaking current value and time can be measured with test
instruments for DIN VDE 0413, part 6.

Fuse Replacement
All fuses can be accessed from outside. Only fuses with the breaking characteristics and
rated current values specified on the front panel may be used.
