Product Usage Instructions
Safety Instructions
WARNING: DISCHARGE TIME
- Stop the motor.
- Disconnect AC mains, permanent magnet type motors, and remote DC-link power supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
- Wait for the capacitors to discharge fully before performing any service or repair work. The waiting time is specified in Table 1.2.
Items Supplied
For J1-J5 enclosure types, a terminal cover must be ordered separately. For J6 and J7 enclosure types, no separate terminal covers are needed.
Mounting the Option
Mount the option according to the provided illustrations.
Electrical Installation
NOTICE: Always use screened motor cables and brake chopper cables. Separate resolver cables from motor cables. Connect the screen of the resolver cable to the de-coupling plate on the frequency converter side, and connect to the chassis (earth) on the motor side.
