PRE POWER UP CHECKS
Electrical Test Before the machine is connected to the factory electrical supply, the following
electrical tests must be performed:
1. Ensure the mains isolator switch is in the OFF position.
2. Remove the front cover of the machine to gain access to the mains isolator
switch.
3. Remove the front cover of the mains isolator switch.
4. Perform a visual inspection of the mains isolator switch ensuring the follow-
ing:
a. The earth input and earth output cables are connected to the earth tag.
b. The live input is connected to the top of the isolator switch on the left hand
side.
c. The live output is connected to the bottom of the isolator switch on the left
hand side.
d. The neutral input is connected to the top of the isolator switch on the right
hand side.
e. The neutral output is connected to the bottom of the isolator switch on the
right hand side.
5. Ensure that all six cables are secure and no bare wires are showing.
6. Connect the two probes of a digital volt meter (DVM) together and ensure
that the DVM is reading 0Ω.

7. Measure the resistance between the following points ensuring that all the
measurements are greater than 2MΩ:
a. Earth tag and the live output.
b. Earth tag and the neutral output.
c. Isolator mount and the neutral output.
d. Isolator mount and the live output.
8. Measure the resistance between the earth tag and all three isolator mount
securing nuts ensuring that all measurements are less than 0.5Ω.
9. Remove the rear cover of the machine (front cover on type 4 machines).
10. Measure the resistance between the following points ensuring that all
measurements are less than 0.5Ω:
a. PC earth stud and a securing screw that secures the PC to the machine
frame.
b. M36 earth stud and a securing screw that secures the M36 to the machine
frame.
c. M37 earth stud and a securing screw that secures the M37 to the machine
frame.
11. Refit the mains isolator cover.
12. Refit the front cover.
13. Before refitting the rear cover, check the three circuit breakers on the M37
Power Supply Enclosure are in the ON position.
14. Refit the cover removed in Step 9.
