The location of the equipment split line may result in the wire being disconnected at the device it is
feeding. The wire bundle will be tagged and identified. Confirm correct rotation of 3 phase devices after
the wiring connections has been completed.
Control wire: this wire is typically broken near the split line, to be reconnected at either a enclosed
terminal block, junction box or extended to a nearby control panel. Each wire or wire bundle will be
tagged and numbered to indicate the location it is sent to.
Sensor wire shield: The drain wire from the shield must be grounded (at one end only). A ground
connection point is available for connection at the point of termination.
All loose wiring must be securely fastened to the equipment casing upon completion.
PIPING, ELECTRICAL OR CONTROL SERVICE CONNECTIONS
DO NOT install anything that will interfere with equipment access or the rating plate.
Engineered Air equipment is constructed with cabinet and floors designed to prevent water from entering
the building through the installed unit. When ordered, factory installed pipe chases and/or electrical
chases are built into the unit floor. Factory chases are provided with covers that need to be replaced and
sealed after piping and electrical connections are made.
All penetrations through the unit walls must be caulked and sealed to prevent air and/or water from
entering the unit.
ELECTRICAL INSTALLATION
DO NOT install anything that will interfere with equipment access or the rating plate.
The unit must be electrically grounded and all wiring must be installed in accordance with the National
Electrical Code, ANSI/NFPA 70, and/or the Canadian Electric Code CSA 22 ‐ 1 and to the approval of the
authorities having jurisdiction. THE FLOOR OF THE UNIT HAS BEEN MADE WATER ‐ RESISTANT. DO NOT
CUT OR DRILL HOLES IN THE FLOOR OR USE PENETRATING FASTENERS. Field wiring diagrams, internal
wiring diagrams and operating functions are included in the control cabinet. The power requirements are
indicated on the rating plate. Where field wiring of control circuits is required, take care to size the field
wiring for a maximum 10% voltage drop. The control circuit ampacity is noted on the field wiring diagram.
See the field wiring diagram for requirements for shielded or twisted pair wire for solid state devices.
