Technical data

Route the cables forming the 3 phase power supply via
the same hole in the motor terminal box gland plate,
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 must be replaced by a
non-metallic gland plate.
DO NOT cut wires to final length or make final
connections to the motor or starter power input
terminals until approved by a York representative. To
ensure correct 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.
Route the main earth cable via the motor terminal box
gland plate to the main earth connection stud on the side
of the box.
Route the single phase control supply to the control
panel with bare wire ends of maximum cable size 4 mm².
Also connect an earth wire to the earth terminal using
the M4 lug.
DO NOT make final power supply connections to control
panel 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.
4.19.2 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 panel 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.
