Verify Previous Installation Steps
Perform the following verification checklist after installation of batteries and wiring:
Step Action
1.
Verify cabinet is properly grounded (using Digital Multimeter (DMM)).
2.
Verify the ac equipment ground is properly connected.
3.
Verify the correct ground cable gauge is used. Use the standard grounding principles for your
office.
4. Verify the ac voltage supplied matches the ac input voltage of the rectifiers.
5. Verify all cables are properly installed for the distribution and marked with labels to identify
them as 48 volt or 24 volt circuits.
6. Examine to assure no sharp corners are in contact with dressed wires. Modify to correct any
problems found.
7.
Check for conductor clearance within the bay associated with high power.
8. Check that all breakers are off and all fuses not inserted.
9. Verify the battery contactors are open, if equipped. Manually operate them to the open position,
if necessary, by pushing the contacts apart.
10. Verify the polarity of all battery cables (using DMM).
11. Verify no shorts are present between frame ground and the ac service. Measure resistance from
each ac input line terminal block position to frame ground.
12. Verify shelves and rectifier positions are properly identified. Label positions as necessary.
13.
Verify battery negative cables are connected to the appropriate bus bar.
14.
Verify battery positive cables are connected to the appropriate bus bar.
15. Visually verify the RS485 cables are properly installed and that shelf ID settings at the rear of
the frame are: [Shelf 1, Shelf 2, Shelf 3, etc.] from top to bottom.
