Bolt-In Breakers or TPL-C Fuse Holders
7
Configure Millennium II controller RPM Shunt Channels per site installation instructions (if equipped with RPMs)
– refer to RPM manual.
Shunts:
Fuse Holders 50 mV, 1500 A
Breakers
25 mV, amp rating same as breaker rating, e.g. 600 A breaker has 600 A, 25 mV shunt.
Configure RPM channel descriptions, A, and mV in Millennium II controller for each load shunt.
8
Verify polarity (using a voltmeter) of the voltage between the Return bus and the distribution input bus.
9
Verify wiring polarity at the input of the load equipment.
Leave breaker switches in the OFF position until the load equipment is ready to be energized.
Verify Installation
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 the 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 labeled as 48 V or 24 V.
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 frame associated with high power.
8
Check that all breakers are OFF and all fuses not inserted.
9
Verify the battery contactors (LVBD) 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.
Example is for 7-shelf (row) system (front view).

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 cables 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.
