CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when handling
parts.
CAUTION
!
3. Determine where each component will be mounted:
S
Modem Enclosure: Mounted vertically, on a side of the
cabinet’s exterior
S
Gateway (Coordinator): Mounted inside the cabinet,
such that allows access to the keypad and display.
Mounting location examples include, mounting within
the unit control box, on a side wall within the unit, or
any available panel. Ensure the selected mounting loca-
tion does not cause damage to coils or existing compo-
nents.
S
Antenna & Mounting Base: Mounted on top of the cabi-
net
S
Relay: Located inside the cabinet such that it reaches
cooling and heating control lines
S
Transformer: Located inside the cabinet such that it can
reach:
a. Transformer primary--side wires will be attached to the
rooftop unit’s load--side leads
b. Transformer secondary--side wires will be attached to
the Gateway (Coordinator) power wires (1 & 2) and
modem power lines (24 & 25). See wiring diagram.
Mount Modem Enclosure:
S
Modem enclosure should be mounted vertically on an exterior
fixed panel as close to the top of the cabinet as possible, in a
position that allows the cover to be opened.
S
DO NOT MOUNT THE MODEM ENCLOSURE ON ANY
REMOVABLE DOORS
ACCESSORY RELIABILITY HAZARD
Failure to follow this caution may result in accessory
component damage.
Installation of Modem Enclosure on moveable doors may
make it difficult or impossible to remove doors. This may
also result in dropping the door and damaging the attached
component or severing wires.
CAUTION
!
S
Choose a side of the cabinet with the least exposure to the sun if
possible.
S
Ensure the enclosure’s cables can reach the Gateway
(Coordinator)’s cable inside the cabinet.
S
Pass the cables to the cabinet inside the rooftop unit using
existing holes if available, or drill one so the cables can reach the
control panel.
S
Secure the cables using the black plastic gland (Hand--tighten).
Mount Gateway (Coordinator):
S
Ensure the selected location for the Gateway (Coordinator)
allows access to see the display & use the keypad. (See Fig.4 )
S
Ensure extension wire from the Antenna Mounting Base can
reach the top of the Gateway (Coordinator).
S
Securely mount the Gateway (Coordinator) using four of the
Mounting Screws
