•If you are unsure about any part of these instructions, consult an electrician.
For Support- Please contact your commissioning agent or installer, or open a support ticket at- https://support.synapsewireless.com/
INCLUDED MATERIAL
•Wetting Capacitor: For light dc loads of < 0.3a ,e.g. dry contact applications, the supplied wetting capacitor must be connected across the relay
terminals to avoid possible malfunction due to oxidation of the contacts. See page 5 for details.
NEEDED MATERIAL
•Screwdriver: A #2 Phillips is required to remove the cover and connect the cables to the terminals.
•Mounting: Mounting brackets are included. Mounting hole fits #10 screw
•Conduit: To maintain the IP rating of the unit, it must be installed with the PG16 cable gland with embedded o-ring supplied or with weather-proof 1/2”
conduit fittings at the power/relay connection entry point.

MOUNT THE CONTROL CONTACT
NOTE: For best RF performance and signal strength, do not mount this device inside a metal box.
Final installed unit should also be mounted with open space on 2 or more sides.
1. Select a suitable installation location for the Control Contact (e.g., close to the load that will be controlled)
2. Mount the Control Contact using the brackets included.
3. The installer is expected to select the correct hardware for mounting to the type of material they are working with.
CONNECTING POWER AND SWITCHED LOADS TO THE CONTROL CONTACT
NOTES:
•Disconnect all power before installation or service.
•The COM/GND terminal of the Control-Contact 24VAC/VDC power input should not be tied to earth ground.
•The Relay Circuits are separated from the power circuits once they are in the enclosure. Follow the NEC guidelines for
conductors in the conduit to get through the gland into the enclosure. To maintain a watertight connection, the cables going
through the gland must be in a single sheath.
oNEC Section 725.136(I) allows Class 2 conductors to be installed with conductors of electric light, power, and Class 1
circuits when a minimum 2‐inches of separation is maintained or if all of the Class 2 circuit conductors are in non–
metallic-sheathed cables in addition to the insulation on the conductors.
•The cable gland fits cable sizes .210” - .334” (5.3mm-8.5mm) PN: Heyco M3219GBH”
1. Open the enclosure cover and remove the metal bracket by undoing the two bottom screws. These are captive screws and will
remain attached to the bracket. See Figure 1A.
2. Feed the cable/wires through the cable gland. A 16AWG-5 conductor jacketed cable, 0.26”- 0.54” diameter, is recommended to
maintain the IP rating of the enclosure. See Figure 1B.

THERE ARE 3 WAYS TO POWER THE CONTROL CONTACT, SELECT THE BEST OPTION FOR YOUR APPLICATION
NOTE- The power connections are inputs ONLY and are exclusive. Do not connect AC and DC to the device.
•POWER OPTION 1: 120VAC
•POWER OPTION 2: 24VAC
•POWER OPTION 3: 24VDC
POWER OPTION 1: 120VAC
For 120VAC power: Connect the 120VAC power wires to wire terminals L (Line) and N (Neutral) and connect the earth ground wire to G (Ground).
POWER OPTION 2: 24VAC
For 24VAC power: Connect the 24VAC power wires (e.g. from an HVAC 24VAC transformer) to wire terminals 24VAC/DC and COM/GND maintaining the
correct polarity.
POWER OPTION 3: 24VDC
For 24VDC Powered: Connect the DC power supply wire (+) to 24VAC/DC and (-) to COM/GND.

SWITCHING LOADS- CHOOSE FROM THE FOLLOWING:
NOTE: The relay in this device does not latch. If the device loses power, connections will default to the “normal” state. The normally open terminal will
be open to common, and normally closed terminal will be closed to common. Please ensure you wire this power-loss default to the safest state
possible. Avoid mis-wiring. Pay attention to the NO and NC contacts.
120VAC Load relay Connections: Connect the Line (hot) wire to the relay wire terminal C (Common) and depending on the required Relay Logic
connect the Load wire to the NO (Normally Open) or to the NC (Normally Closed) terminal. See Figure 5. Never connect the Load to both the NO and the
NC terminals.
24VAC Load relay connections: Connect the 24VAC Live wire to the relay wire terminal C and depending on the required Relay Logic
connect the Load wire to the relay terminal NO or to the NC terminal.
24VDC Load relay connections: Connect the 24VDC (+) wire to the relay wire terminal C and depending on the required Relay Logic connect
the Load wire to the relay terminal NO or to the NC terminal.
Note: for light DC loads of < 0.3A ,e.g. dry contact
applications, the supplied wetting capacitor must be connected
across the relay terminals to avoid possible malfunction due to
oxidation of the contacts.

FINAL STEPS
1. Replace the wiring cover
Reinstall the metal bracket, ensure the wires are properly routed under the bracket notches and tighten the two bottom screws,
torque to 20 in-lbs.
2. Tighten the cable gland
Tighten the cable gland over the cable/wires and torque to 40-70 in-lbs, depending on the cable diameter and harness. to ensure
the enclosure is properly sealed.
3. Set the Manual Override Switch
The Manual Override Switch is a 3 position DPDT toggle switch. The switch has a 0.5” long locking lever to actuate the switch, for
safety the lever needs to be pulled to change the position of the switch.
When switched to the top position, the switch forces the relay to turn ON, it forces the relay OFF when switched to the bottom
position and the relay is in AUTO (driven by the wireless interface) when switched to the center position. The Switch should be set
for AUTO for normal operation.
4. Close and latch the enclosure cover
Check the gasket to make sure it is properly seated in the guide on the enclosure cover before latching closed. With the gasket
properly seated in the guide, close and patch the enclosure cover.
5. Configure the device
Set up a zone and schedule in SimplySnap to automatically control the attached loads.
