Inspection and maintenance

The valid operating manual of the manufac-
turer shall be ob served for inspection, main-
tenance and repair. During servicing, it is par-
ticularly important to check those compo-
nents upon which the type of protection
depends.
The functional characteristics of the apparatus
shall remain stable over long periods of time,
thus eliminating the need for regular adjustment
or similar. Also, no other maintenance work is
required.
As soon as malfunctions are observed, disas-
semble the apparatus. Internal parts cannot be
serviced by the customer. Return the apparatus
