SPECIFICATIONS

This device has a monitoring system that can protect an electrical distribution circuit by switching a load on or off based on its main breaker size and on what the system usage is. It will act to prevent systems connected to it from overloading the electrical distribution circuit by turning off the power to the load connected to it for the duration that the computational algorithm determines it is needed as related to the main breaker sizing.

INSTALLATION INSTRUCTIONS

STEP 1: CHECK THE CONTENTS OF THE PACKAGE

Model#: DEVICEXXX-XXX

1 x Controller & enclosure, 2 x Current monitoring devices 1 x Bag including miscellaneous pieces, 1 x Installation instructions

STEP 2: PREPARING FOR THE INSTALLATION

Disconnect power to all devices being worked on or within an unsafe distance to the working area.
Select the device installation location.
– The recommended place for the device to be installed is directly above the main panel and with adequate air circulation. See Installation Diagram for suggested locations. Other locations are acceptable.
– NOTE: The DEVICE controller must be mounted so that the nameplate remains visible at all times. It must not be installed in the orientation with the cover facing the ground.
DO NOT install the device:
– Outdoors
– In a location with a high level of risk as defined by local electrical codes or in a hazardous location. – for example, nearby flammable materials, explosives or fuels, chemical products, and hazardous vapors.

STEP 3: INSTALLATION OF THE DEVICE

Remove the two cover screws and enclosure cover.
Attach the device securely to the desired location. Do not mount with the cover plate facing down.
Remove the black cover of the internal control partition by unscrewing the two screws inside the enclosure.
Install current monitoring devices on the main service wires to be monitored by clipping them onto each main line paying attention to the arrow inside the window and labeling that indicates the direction of current flow and orientation of connection. Current monitoring devices should be installed so that no part of them will directly conduct electricity from exposed live parts. Ensure the closing clip is secured shut and fastened with a zip tie. Fasten the current monitoring devices in place with the zip-ties. Review and observe all local safety procedures when installing and working near live parts.
Ensure main line lugs have not come loose with the installation of current monitoring devices.
Install the current monitoring device wire leads from the service area to the device control partition area ensuring the polarity of the leads remains as from the factory. If connectors are disconnected the factory-installed polarity must be maintained. (DO NOT coil wires near any other 120/240V wires as this may cause improper operation. DO NOT short wire leads together or to ground at any time. Install leads with mechanical protection from damage.)
Insert the two blue current monitoring device connectors into the corresponding two blue receptacles on the control board. Maintain wire polarity in the blue connectors and ensure wires and connectors are seated well in each receptacle.
Set up switches and observation time dial as indicated in the chart and diagram on the next page or the back of the cover. These are located on the control board.
Re-install the cover of the control partition inside the enclosure by reinstalling the screws removed previously and tightening them until snug. Be sure not to pinch any wires or strip the screws.
Install electrical lines from the supply breaker for the controlled device to the marked LINE SIDE of the contactor and bonding/ground attachment. See Torque Settings on page 3.
Install electrical lines from end device to be controlled (ie: EV charger) to LOAD SIDE of contactor and bonding/ground as required by local electrical codes. See Torque Settings on page 3.
Install enclosure cover. Check for ground faults and when safe to do so, energize. (Note: The contactor will not close until a computational observation time of between 0 – 10 minutes. The algorithm must be satisfied the system will remain below 80% of the rated main breaker and other values included in it. This is partially dependent on the setting of the timer adjustment screw (white) on the control board. If this observation time is too long it can be adjusted by turning this dial setting counter-clockwise but this should not be set below 1 minute to avoid contactor chattering.)

See setting diagram chart and continued instructions

MAINTENANCE

Do not use any cleaning solvents on the devices.

Electrical connection must be inspected, maintained, and re-torqued every year by qualified personnel to maintain safe and proper operation. The interval may be increased in areas with high ambient temperature variance.

TROUBLESHOOTING

Contactor does not close (energize) at the initial device powered on:

There is an initial delay when powered on while the computer algorithm is checking the electrical service. The contactor will not close until a computational observation time elapses between 0 – 10 minutes. During this time the current draw on the main electrical service wires must remain below threshold current values of 80% of the main breaker size. This is also dependent on the setting of the timer adjustment screw (white) on the control board referred to in step 8 and the chart in the instructions and other algorithmic values. If this observation time is too long it can be adjusted by turning this screw counter clockwise. You can check for contactor operation by turning this adjustment all the way counter clockwise and waiting for the current on both monitored main service wires to drop below 80% of the main service breaker rating for a short time as associated with the internal algorithm. The contractor should close shortly after this happens. This adjustment must not be left in this position but should be set above 1 minute to avoid contactor chattering and premature failure. If this test shows the device is not working, then check for 240/208V power at the line side terminations on the contactor. If there is power present, next check that both wire connectors (stack-ons) on the terminals plugged into the line side of the contactor are secure. Once this is confirmed, then check that the wire connectors on each side of the contactor coil are secure. If they are secure, next check the field-installed wires in the contactor lugs on both the line side and load side are properly installed and that voltage is present on the line size wires. Ensure the current monitoring device connections are the correct polarity. Ensure the current monitoring device wires and connectors are fully seated in the respective connector and receptacles. If these items all have been checked and the issue is not resolved, please de-energize and contact the manufacturer.

Improper operation of contactor:

Check if the length of the current monitoring device lead wires are coiled close to other 120/240V lines and if so move them away from the area as this can cause improper operation. Next check if the current monitoring devices are closed securely. If they are check if the current monitoring devices are installed in the correct orientation with the arrow shown inside the current monitoring device eye (window opening) pointing in the direction of the current flow. If the orientation is correct, then verify that both service wires are consistently well below the operational current specifications for up to 15 minutes (depending on the setting of timer adjustment) with an amp meter. Ensure the current monitoring device connections are the correct polarity. Ensure the current monitoring device wires and connectors are fully seated in the respective connector and receptacles. If all these items are verified and improper operation still exists, please de-energize the device and contact the manufacturer.

Contactor chatters on and off or makes loud humming noise:

Verify that the timer adjustment screw (white) on the control board is set approximately ½ way between the left and right rotation. If adjustment is needed insert a screwdriver and adjust accordingly. Reset power to the device. The farther this is set clockwise the more time the computer algorithm will watch the service before allowing the load side (ie: EV charger) to energize. Ensure the current monitoring device connections are the correct polarity. Ensure the current monitoring device wires and connectors are fully seated in the respective connector and receptacles. If this is completed and the contactor is still chattering or making a loud noise, please de-energize the device and contact the manufacturer.
The device is built with noise isolators between the contactor and the enclosure. If the screws that attach the contactor to the enclosure are overtightened any humming sound may be amplified. These screws can be adjusted to allow for acoustic separation.
