Connect a Surge Protective Device
A surge protective device decreases the surge voltage generated when you switch an inductive load near the drive.
Inductive loads include:
•
Magnetic contactors
•
Electromagnetic relays
•
Magnetic valves
•
Solenoids

Magnetic brakes.
Always use a surge protective device or diode with inductive loads.
Note:
Do not connect a surge protective device to the drive output side.
