Low Voltage Electrical Connections
Recommended wiring for the OWL to the S1 or C1 is a 4 conductor 18 gauge shielded cable.
Use 2 conductor 18 gauge shielded cable for communication between all the units.
Note: Communication wire length should be limited to 500 feet total in any wiring run
(for example: five sections 100 feet each daisy chained together or one continuous piece equals 500 feet ).
(1). These wires can be included in the wire bundle with the communication wires, but will be connected to only one
of the RAMVAC equipment controls in the system.
(2). A separate transformer is used on OWL only if the 12VDC is not supplied by the S1 or C1.
