All wiring shall be installed according to the requirements of the authorities having jurisdiction. Field
wiring, internal wiring diagrams and unit operating functions are included in the control cabinet of the
unit. The power requirements are indicated on the rating plate.
SPLIT UNIT WIRING
All split wiring must be completed by an electrician prior to starting the equipment. A number of
different methods are used to reconnect the wiring.
Power wire: this wiring is generally not broken or spliced, and will extend from the device back to the
contactor or terminal block inside the electrical panel(s). The wire will be tagged to identify which panel it
extends to and will be numbered to the corresponding connection.
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.
Caution:
Temporary Power Generation
The warranty will be void if the voltage being fed from any temporary generator is not
within 10% of the nominal rated nameplate voltage and voltage imbalance shall be
limited to 2%. A power monitor shall be installed by others to properly monitor power
quality and conditions.
All generator sets shall be provided with overcurrent and earth-fault protection. The
protective apparatus should be capable of interrupting, without damage, any short-
circuit current that may occur.
Warning:
No unspecified external load shall be added to the control transformer circuit(s) or to
the main power circuit(s).
