SECTION 2: POWER SUPPLY
TERMINATION
2-1 PANELBOARD
Panelboards are shipped with the
Controller’s Chassis power supply for the
electronics terminated to the correct
voltage. There is no need for the personnel
installing the panel to supply connections to
the power supply of the 5X-Controller
Chassis or 7X-Expansion Chassis. Please
verify that the panels supply voltage
matches the voltages specified on the label
of the panel. On the left side of the 5X-
Controller Chassis find the wires feeding
primary side of the power supply. If wire is
not used for the application, it should
contain isolating cap. Wires are color coded
as follows:
- RED 120VAC
- YELLOW 277VAC
- BROWN NEUTRAL
- GREEN GROUND
2-2 RELAY PANEL, EXPANSION / CONTROL
CABINET
The personnel installing the Relay Panel or the
Expansion/Control Cabinet are responsible for
providing and terminating the power wires to
these panels.
If the trim is installed, remove the trim (for the
Expansion/Control Cabinet, remove the door
and the power supply cover). There are two
terminal sets on the power supply. The right
side of the power supply is marked “Trans-
former Tap 120/277VAC” and the left side is
marked “Line Power 120/277VAC”.
On the Transformer Tap terminal, verify the
correct jumper position for the voltage that
you will be connecting to the panel. Move the
jumper if necessary. The correct jumper
positions are:
- 277 to COM for 277VAC
- 120 to COM for 120VAC.
Note: All units are generally shipped with the
jumper strapped for 277VAC. However, be
sure to verify this setting. Applying 277VAC to
the unit set for 120VAC may damage the unit.
On the Line Power terminal, connect
ground wire to the terminal marked:
“GND”. Connect neutral wire to the
terminal marked: “LO”. Connect hot
wire to the terminal marked: “HI”. For
power connections use a minimum #12
AWG copper wire.
