T24 +24V
The +24v supply from the drive (terminal T24) is for use with the drive only. It
should be used with the RUN circuit (terminal 5) to control the drives internal
relay to switch the contactor and can be used with the ENABLE circuit (terminal
T20).
C a u t i o n
CAUTION
DO NOT use the +24v supply to power any circuit or device external to the
drive. This includes external relays, PLC's, and any other equipment.
Using the +24v external to the drive could result in drive malfunction or damage,
damage to connected equipment, and could endanger personnel.
