(1) Refer to the Kinetix 5500 Servo Drives User Manual, publication 2198-UM001 , for example configurations.
Grounding Screw Configuration Benefits of Configuration
Grounded (wye)
Both screws installed
(default setting)
• UL and EMC compliance
• Reduced electrical noise
• Most stable operation
• Reduced voltage stress on components and
motor bearings
• B-phase corner ground
• AC fed ungrounded
Both screws removed
• Helps avoid severe equipment damage when
ground fault occurs
• Reduced leakage current
SHOCK HAZARD: To avoid hazard of electrical shock, perform all mounting and wiring of the
Kinetix 5500 drive prior to applying power. Once power is applied, connector terminals can have
voltage present even when not in use.
ATTENTION: Plan the installation of your system so that you can perform all cutting, drilling,
tapping, and welding with the system removed from the enclosure. Because the system is of the
open type construction, be careful to keep any metal debris from falling into it. Metal debris or
other foreign matter can become lodged in the circuitry and result in damage to components.
