◆ 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.
