Input Power Connections
3.4 Input Power Connections
Depending on which Power Supply is plugged-in, the Wall-Mount Chassis can be
powered from 24 Vdc, 48 Vdc, 130 Vdc or 120 Vac. The input power is connected
to the Chassis through the input terminal block. For a view of the pinout, see
Figure 2 on page 17 and Table 2 on page 18.
When powered from AC, the Live wire is connected to the “L” terminal, the neutral
wire is connected to the “N” terminal and the power ground is connected to the
“GND” terminal. When powered from DC, the “-” terminal will be connected to the
negative input lead and the “+” terminal will be connected to the positive lead.
If multiple Chassis are being used, each must have its own power cable.
A fuse is provided on the live/positive input lead to provide input overcurrent
protection. That fuse must be replaced with the same type and rating. See section
2.1 on page 14 for more information.
3.5 Chassis Wiring
3.5.1 24 V systems
When using 24 V Power Supplies, the Chassis can provide floating 24 Vdc, -24
Vdc or +24 Vdc referenced to ground. Connect the positive output of the Chassis
(0 V) to the positive input of the equipment and the negative output of the Chassis
(-24 V) to the negative input of the equipment.
Q
Unit is factory set for -24 Vdc output.
Refer to Figure 4 on page 26 for a view of the 24 V wiring.
