Mount 4--Pole Relay
S
Securely mount the 4--pole relay using the 2 supplied mounting
screws.
S
The 4--pole relay has a set of pre--kitted wires to simplify
installation.
S
When the coil is energized, this will allow the control signals to
pass on to the control board.
S
The rooftop unit’s Y1 and Y2, W1 and W2 control lines should
be connected through the relays’ Normally Open control points
(See Fig. 11) using the pre--kitted wires.

Connect Current Sensors (CT
S
)
S
The two current sensors should be carefully clamped around
different legs of the load--side leads, preferably L1 & L2 (L1 is
often the leg powering single--phase fan motors; confirm via
reading current with a clamp--on meter). (See Fig. 9)
S
Ensure the locking tabs are fully secured.
S
Plug the Molex connector pair from a CT to one of the matching
connectors on the Gateway (Coordinator) cable.
Connect Data Cables
Attach the 3--wire Molex connector from the Modem Enclosure to
the 3--wire Molex connector from the Gateway (Coordinator)
(wires 3, 4, 11, 12).

Fig. 8 -- Antenna and Mounting Base
S
Locate a smooth surface on the top of the cabinet to secure the
Antenna and Antenna Mounting Base. Ensure there is sufficient
slack on the extension cable to reach the Gateway (Coordinator)
(mounted inside the cabinet). (See Fig. 8)
S
Locate a small hole through which the antenna wire can pass
into the cabinet (or drill a hole small enough for the wire).
Ensure a 1/2--in. grommet is used to protect wiring from any
sharp edges.
S
Hand--tightened the Antenna to the Mounting Base.
S
Hand--tighten the Mounting Base’s extension cable to the
antenna mount on the top of the Gateway (Coordinator). Do not
attach the antenna directly to the top of a Gateway
(Coordinator).
ACCESSORY RELIABILITY HAZARD
Failure to follow this caution may result in accessory
component malfunction.
The antenna must be installed outside of the rooftop unit
cabinet to ensure signal broadcast and reception.
CAUTION
!
S
Glue the Antenna Mounting Base to the top of the rooftop unit
using silicone to ensure it remains fixed even under heavy
winds.
S
Use silicone to seal the hole where the antenna cable exits the
cabinet.
