INTERFACE
The interface between the drive system and external devices is divided into two categories: power
supply system and control system.
Power Supply Interface and Ground
The standard power supplies required are the main circuit input of 2400/4160V 3
Φ
and (optional)
control power supplies of 120V 1
Φ
and AC480V 3
Φ
.
The following figure shows a recommended grounding circuit for the related equipment. Grounding
is intended not only for safety but also to reduce noise problems. The control ground bus is mounted on
insulated standoffs. It may be separated from the power ground and run separately to the earth ground with
insulated cable if noise problems are encountered with auxiliary control devices.
Grounding must follow local and national codes
by attaching a properly sized ground conductor
to the drive equipment.
