Inspecting electrical system

DANGER
Touching electrically live parts can be fatal.
Improper or inadequate inspection and mainte-
nance can lead to device components becoming
live during device operation.
a) The electrical system must be inspected and
serviced by a qualified electrician.
b) Once the work has been completed, all safety
devices must be reinstalled as specified and
checked.
a) Check all the electrical components of the de-
vice for visible damage, loose contacts and con-
tamination. To do this, remove the guard in or-
der to inspect the internal wiring. Remove any
external contamination with a lint-free cloth and
replace any defective or damaged components.
b) If used commercially in Germany: An annual
DGUV V3 inspection in accordance with Ger-
man Statutory Accident Insurance (DGUV) rules
must be carried out and documented.
 The inspection of the electrical system of the
device is now complete.
