When used under the conditions specified in
the section "Technical data", the relay requires
practically no maintenance. The relay includes
no parts or components that are sensitive to
abnormal physical or electrical wear under nor-
mal operating conditions.
If the environmental conditions on site differ
from those specified, as to temperature and
humidity, or if the atmosphere around the relay
contains chemically active gases or dust, the
relay should be visually inspected during the
relay secondary testing. The visual inspection
should focus on:
- Signs of mechanical damage on relay case and
terminals
- Dust accumulated inside the relay cover or
case; remove carefully with compressed air or
a soft brush
- Signs of corrosion on terminals, case or com-
ponents inside the relay

If the relay fails in operation or if the operation
values considerably differ from those stated in
the relay specifications, the relay should be given
a proper overhaul. Minor measures, such as
exchange of a faulty module, can be taken by
personnel from the customer's instrument work-
shop, but major measures involving the electro-
nics are to be taken by the manufacturer. Please
contact the manufacturer or his nearest repre-
sentative for further information about check-
ing, overhaul and calibration of the relay.
Note!
The static protection relays contain electronic
circuits which may be damaged by static dis-
charge electricity. Make sure that you are prop-
erly earthed when you are going to withdraw
modules from the relay cases.
Note!
Static protection relays are measuring instru-
ments and should be handled with care and
protected against damp and mechanical stress,
especially during transport and storage.
