Technical data

DO NOT make final power supply connections to control
centre until approved by a YORK representative.
To ensure proper motor rotation the starter
power input and starter to motor connections
must be checked with a phase sequence
indicator in the presence of the York
representative.
The figure below shows the power wiring for the motor
connections. (Refer to wiring labels in motor terminal
box for details to suit motor voltage and amperage.)
For high voltage applications motor leads are furnished
with a crimp type connection having a clearance hole for
a 3/8" bolt, motor terminal lugs are not furnished.
For low voltage applications terminal block connections
are fitted.
4.20.2 Units with Solid State Starter (Optional)
Units equipped with a solid state starter require a three
phase power supply plus earth to the starter. Power
wiring from the starter to the motor is factory fitted.
Power wiring to the control centre is also factory fitted
via a control transformer supplied with the Solid State
Starter.
Route the cables forming the 3 phase power supply via
the same hole in the solid state starter gland plate /
gland box on top of the starter, using a suitable cable
gland, to ensure that no eddy currents are set up in the
metal gland plate. If separate entries for each cable
forming the 3 phase supplies are used, the metal gland
plate / gland box must be replaced by a non-metallic
version.
DO NOT cut wires to final length or make final
connections to starter input terminals until approved by
a York representative.
To ensure proper motor rotation the starter
power input connections must be checked
with a phase sequence indicator in the
presence of the York representative.
Route the earth cable via the starter gland plate to the
main earth connection stud on the side of the starter.
4.21 Control Connections
Customer voltage free contacts must be
suitable for device contact rating to be 5 mA at
115 Vac. If the voltage free contacts form part
of a relay or contactor, the coil of the device
