Product description
The Gavita ECM1 external contactor module is an add-on product to the Gavita EL2 Master Controller. When connected to the controller, the
contactor will switch auxiliary equipment based on the output of the controller.
ECMs can be used to switch auxiliary equipment during lights-on and lights-off periods. The ECMs and all the auxiliary equipment connected
to it are also governed by the controller’s shut-off safety features.

Keep the ECM away from water, extreme temperatures, moisture, dust and
contamination.
!
Caution!
Mount the ECM close to the wall outlet or ensure you have an extention cord present to
connect the ECM to the mains.
!
Caution!
Mount the ECM within signal cable length of the controller or use a suitable longer cable
(<20 meters)
!
Note:
Fasteners are not included.
•
Screw one screw in the wall

Connecting the ECM to the controller
!
Warning!
Never connect the cage clamps of the ECM to any other device than the Gavita EL2
controller.
!
Warning!
Never connect more then one ECM to each set of cage clamps of the controller.
!
Warning!
Ensure all wire ends are fully inserted into the cage clamps. Exposed wire endings can be
dangerous!
The ECM cable is connected to both the Controller and the ECM by means of cage clamps.
The controller has two sets of cage clamps named: “ECM1” and “ECM2”. “ECM1” follows the output of
the main channel of the controller. “ECM2” works alternatingly with “ECM1” and is inactive when the
main channel is active (and the other way around). For more information on connecting ECMs to the
controller, consult chapter 7 and 8.
•
Press the white buttons above the contact openings of the cage clamps to open them
•

. A cable of up to
20 meters may be used as long as its endings are hard/tinned and stripped to less then 8 mm
•
Release the buttons to lock the wires in place
•

!
Warning!
Ensure the voltage and current requirements of the auxiliary equipment do not exceed
the capacity of the ECM and the local cabeling! (see chapter 8) Use the ECM to switch an additional,
heavier contactor if your application requires a higher current.
!
Caution!
Gavita recommends you install and connect the ECM before plugging it into the mains.
