Inspection report
II. Electrical measurement(Use only measuring instruments according to DIN EN 62353 (VDE
0751-1))
Note: To minimise measuring errors, route the test leads as far away as possible from and not par-
allel to the power cables and handset cables of the bed. Also observe the operating instructions for
the measuring instruments used
Insulation resistance: To be carried out only if there are doubts about the electrical insulation,
such as:
If the customer’s RCD (residual current circuit breaker) has tripped several times
If defective electrical housings are found and at the same time there are signs of spilled liquids/
contamination there that could affect the insulation
1. Plug the mains cable/switching power supply into the test socket of the measuring instrument
2. Connect the probe at the common measuring point of all applied parts: = bare screw of the
backrest swivel joint underneath the backrest on the mattress base frame
3. Start the measuring procedure on the measuring instrument; measuring voltage = 500 V DC
