5 Maintenance and repair

The repair work which can be done on the S-50 / 80 / 110 / 120 DC by the user is limited to the
replacement of fuses and lamps. Fuses, lamps and tools are included in the service kit.

Repairs to the high-voltage unit are not permitted.

No more testing must be done if the oil level drops.

If the HV test set is defective, the complete set must be sent in for repair, as the operating unit is
matched to the high-voltage unit (interchangeability not guaranteed).

The S-50 / 80 / 110 / 120 DC is test equipment and as such must be handled and looked after
with care.

Moisture
, external soiling, direct sunlight and ambient temperatures in excess of 55°C must be
avoided.
NOTE!
The high-voltage unit must only be transported in an upright position.
