Checking the Motor
If this job reuses existing rotating equipment, the equipment must be checked for insulation
breakdown before proceeding.
1. Disconnect all motor and brake wiring.
2. Perform an insulation test between these wires and the frame of the related equipment
using a Megohm meter to subject the insulation to the same high voltages that would be
present during escalator operation.
3. A minimum insulation resistance of 100k Ohms is required.
4. Correct any insulation problems before proceeding with installation. Insulation prob-
lems may indicate a serious problem in the equipment.
Wiring the Motor to the Controller
Incoming power to the controller and outgoing power wires to the motor must be in their
respective grounded conduit.
It is very important that AC motor wires be kept separate from control wires both inside and
outside the controller cabinet. Use a shielded power cable between the motor drive and the AC
Motor stator connections to reduce RFI/EMI noise (Siemens Protoflex - EMV or equivalent).
The shield must be terminated to earth ground at both ends. Keep the AC power wiring separate
from the control wires.
1. Refer to the job print showing the AC drive and connections to rotating equipment.
2. Make connections as shown in the job prints. Be certain to follow any schematic notes
regarding wire sizes and any specific motor wiring connections.
