WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.

Low Voltage (AC) Field Wiring Connections
To access the wire entry locations now that the Panel is
mounted:
1. Open the door and remove the two (2) screws on the
right hand side of the Key pad. Swing the Key pad
open, exposing both the wire entries and the back of
the Human Interface Module. As shown in
, connect one end of the three (3) conductor 24 volt
wires to the Remote Panel terminal strip J2-1 (+), J2-2
(-), and J2-3 (Ground).
Communication Link (Shielded
Twisted Pair) Wiring
1. As shown in
, trim the outer covering of
the shielded cable back approximately 1 inch. Do not
cut the bare shield wire off. Strip approximately 1/2
inch of insulation from each insulated wire in order to
connect them to the terminal strip at the Remote Panel.
2. Refer to
and connect the White lead to J1-
1 positive (+) terminal, the Black lead to J1-2 negative
(-) terminal, and the bare shield wire to J1-3 terminal at
the Remote Human Interface Panel.
3. Close the key pad plate. Install and tighten the two (2)
screws removed earlier. Close the outer door and
install the recessed locking screw at the bottom right
hand side of the enclosure to prevent accidental
starting of the unit by un-authorized personnel while
completing the wiring at the Rooftop Unit.
At the Rooftop Unit
Connect the opposite end of the three (3) conductor 24 volt
wire to the appropriate terminal strip as follows:
Note:
Although the 24 volt power is not polarity sensitive,
care must be taken not to connect either the + (plus)
or - (minus) terminals from the Remote Panel to
ground, at the Rooftop unit.
1. Connect the wire connected to the positive (+) terminal
at the Remote Panel to terminal
1TB4-1. Connect the wire connected to the negative (-
) terminal at the Remote Panel to terminal 1TB5-17.
Connect the Ground wire from the Remote Panel to the
unit control panel casing.
Interprocessor Communication Bridge
Module Wiring
1. Refer to
and trim the outer covering of the
shielded cable back approximately 1 inch. Cut the bare
shield wire off even with the outer covering. Strip
approximately 1/2 inch of insulation from each
insulated wire in order to connect them to the terminal
strip at the Unit. Wrap tape around any exposed foil
shield and/or base shield wire.
Note:
The communication link is polarity sensitive.
Therefore, care must be taken.
2. Refer to
and connect the White lead to
1TB5-19 positive (+) terminal and the Black lead to
1TB5-18 negative (-) terminal. (These terminals are
numbered only, reference to color is for clarification in
order to maintain polarity).
Note:
Do not connect the base shield wire to ground at
the Rooftop unit. To insure polarity is maintained
when connecting these links at the Rooftop unit.
