Connect the control panel’s AC input line directly to a dedicated circuit breaker that is not
shared by other appliances or equipment. It is recommended that the circuit breaker
shall be labeled “FIRE ALARM”.
Use a three wire cable (Line, Neutral and Ground wires) of the appropriate gauge
Verify that all power sources to the ECD are disconnected.
Disconnect the ECD AC cable from the mains, so that the ECD ends of the wires can be
handled safely.
Insert the AC input power cable to the control panel enclosure through either the top left
or bottom left knockout opening and keep it separated and distant from the field wiring
and the control panel circuits.
Use appropriate bushing/grommet that fits the knockout openings, to ascertain that there
are no sharp edges, to prevent damage or abrasion to the cable during assembly and
use.
Connect the GND (yellow/green) wire to the dedicated grounding screw located below
the PS, using the appropriate hardware as shown in Fig. 7 below, thus connecting the
chassis to the grounding wire
CONNECT THE GROUND WIRE OF THE AC INPUT CABLE DIRECTLY THE PANEL'S
CHASSIS GROUND SCREW, USING SERRATED WASHERS AS SHOWN.

Then connect the Line and Neutral wires to the proper terminal. Tighten the terminal
block screws.
VERIFY THAT THE ECD IS PROPERLY GROUNDED BEFORE CONNECTING AC
POWER TO THE ECD.
Connecting the batteries: Connect the supplied link wire between the batteries, and then
connect the long Red wire o the + terminal of one battery and to the +bat terminal block,,
and the long black wire to the –terminal of the battery and the –bat terminal block
