Connect the Power Wires
There are two ways to connect the wires for the power supply to the GC3 Panel:
1. Terminal Block:
Securely fasten a 2-conductor power wire (not supplied) to the appropriate PWR+/PWR- screw
positions on the GC3 Panel’s terminal block.
2. Barrel Connector:
A plug-in power supply with a barrel connector can be plugged into the DC power adapter’s
barrel jack on the GC3 Panel.
IMPORTANT: When selecting a wall outlet, never connect the plug-in power supply to a switch-controlled outlet.

Terminal Block
The most common way to connect the AC power supply for the GC3 Panel is to use the system’s terminal block. This
requires you securely fasten 2- conductor power wire (not supplied) to the appropriate PWR+/PWR- screw terminals.
GC3 Panel—Terminal Block
To connect the power supply to the GC3 Panel:
1. Locate an unswitched wall outlet for the plug-in power supply. Do NOT
connect the power supply to the outlet at this time.
2. Route 2-conductor power wire from the plug-in power supply through
the wiring cutout on the GC3 Panel’s backplate. See “Connect the Power
Wires” above.
WARNING!!
The proper wiring sequence for the DC power supply
terminal block is always ground to ground, positive to positive, and
negative to negative. However, grounding the GC3 Panel is NOT
required for proper operations.
3. Insert the positive wire into the PWR+ terminal position. Then tighten
the terminal block’s contact screw.
IMPORTANT:
Do not over-tighten the terminal block’s contact screws.
NOTE:
Terminal 1 only provides power for the GC3 Panel when its power
supply is connected to an AC power source.
