Periodic verification
The following periodic verifications of electrical installations have to be carried out according to the
local or national standards effective at the time of installation. For your Bender products, we recom-
mend:
* This test must only be performed by an authorised electrically skilled person in agreement with the
medical locations concerned.
Before carrying out the tests, please refer to the instructions relating to the functional tests in the
check list. If no national directives apply, you should perform the tests recommended by IEC 60364-
7-710: 2002-11, section 710.62 and DIN VDE 0100-710 (VDE 0100 Part 710):
