6.4.5 Electrical device test to verify correct installation
After concluding the electrical work, you should conduct a test to rule out the possibility
of errors, e.g. insulation faults in the supply voltage and communication. This test must
be carried out by the personnel responsible for the electrical installation. The operator
should obtain written confirmation that the device is in perfect electrical condition.
CAUTION
Do not conduct the tests in a potentially explosive atmosphere.
You will require the permission of the system operator to conduct the test
The use of a multimeter is required to conduct the test. You should check the following

1
Conduct a visual inspection of the interior of the device. There must be no loose wires.
All wires are connected as shown in the circuit diagram. Spare wires have been dealt
with correctly and routed safely.
2.
The supply voltage is 24 V DC. ± 15% is available after switching on the terminals on
the terminal board.
3.
A rating of up to 120 W can be supplied. Connect a load resistor in parallel if
necessary.
4.
Cause a short-circuit and the supply voltage must be switched off within
120 seconds.
5.
Check all switches and fuses outside the device. Is everything accessible and can
everything be switched off and on?
6
Conduct resistance measurements to ensure that all the electrical connections have
low resistance. Check the earthing as well.
7
Conduct resistance measurements to ensure that all the cables are adequately
isolated from each other and to earth.
If you find any discrepancies or errors during the test, repeat the appropriate items in
the installation procedure until all the points are error-free and OK. This concludes the
installation work. Seal the device again correctly.
ATTENTION
Close the device.
Position the hood with the sealing ring and fully tighten the thread. Then
turn the countersunk security screws upwards to the edge of the hood to
prevent the hood being removed accidentally or through ignorance.
