WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which
can remain charged even when the frequency converter is
not powered. High voltage can be present even when the
warning LED indicator lights are
specied time after power has been removed before
performing service or repair work can result in death or
serious injury.
Stop the motor.
•
Disconnect AC mains and remote DC-link power
•
supplies, including battery back-ups, UPS, and DClink connections to other frequency converters.
Disconnect or lock PM motor.
•
Wait for the capacitors to discharge fully. The
•
minimum duration of waiting time is specied in
Tabl e 1.4 and is also visible on the product label on
top of the frequency converter.
Before performing any service or repair work, use
•
an appropriate voltage measuring device to make
sure that the capacitors are fully discharged.

Electrical Installation
NOTICE
Supply the encoder through the VLT® Encoder Option MCB 102. Avoid using external supply for the encoder.
Encoder monitor
The 4 encoder channels (A, B, Z, and D) are monitored, open, and short circuits can be detected. There is a green LED for each
channel which lights up when the channel is OK.
NOTICE
To view the LEDs on the option, remove the cover. Select response to encoder errors in parameter 17-61 Feedback Signal
Monitoring.
NOTICE
Maximum cable length for incremental encoder 150 m [492 ft].
