Maxiva ULX COFDM Series
2.6.3 Checking AC Configuration
The voltage specifications on the transmitter ID panel should be compared to the supply
voltages to be sure they are compatible. Should questions arise the jumpers in TB1 and
TB2 on the AC distribution panel, the IPA and PA backplane jumpers (TB1, TB2, and
TB3), the MOV board jumpers, and the possible neutral connection from the AC
service disconnect to CB23 and CB24 can be verified. These jumpers are described in
the Wiring Diagram, PA Cabinet Main Maxiva ULX 843-5601-001. Select the proper
diagram for the system that is being used. Use the wiring diagrams for proper set up.
The connections are also briefly described below.
• Terminal boards TB1 and TB2 on the AC distribution panel.
Figures 2-7 and 2-8, referred to below, contain outline drawings of TB1 and TB2,
with black boxes representing the jumpers between segments. The critical jumpers
are indicated by the dashed boxes around them.
2.6.3.1 TB1 TB2 Jumpers 1 Cabinet 10 -16 Modules
For 208 to 240 VAC connections in Delta or WYE, TB1 and TB2 have a jumper
between terminals 5 and 6, and none between 6 and 7, see Figure 2-7, top.
For 380 to 415 VAC, connection must be WYE and the jumper is removed from
between terminals 5 and 6 and installed between terminals 6 and 7, see Figure 2-7,
bottom.
2.6.3.2 TB1 TB2 Jumpers 1 Cabinet 1 - 8 Modules
For 208 to 240 VAC connections in Delta or WYE, TB1 has a jumper between terminals
5 and 6, and none between 7 and 8, see Figure 2-8, top.
For 380 to 415 VAC, connections must be WYE and the jumper is removed from
between terminals 5 and 6 and installed between terminals 7 and 8, see Figure 2-8,
bottom.
Correct positioning of the jumpers ensures that 208 to 240 VAC is always applied to
circuit breakers CB19 through CB22.
• Parallel MOV boards (A15A1 & A15A2). MOV board jumpers are shown on sheet 8
of the PA Cabinet Main Wiring Diagram, drawing number 843-5601-001.
