Cable Shielded twisted pair, impedance
100…150 ohm
Termination Daisy chained bus without drop out
lines

Communication type Serial, asynchronous, half duplex
Protocol Modbus
Clearance and creepage distance
The clearance and creepage distance between I/O connections and
mains circuit is 5.5 mm, which guarantees safety insulation of
overvoltage category 3 (IEC 60664-1).
Efficiency
Approximately 95 to 98% at nominal power level, depending on the
drive size and options
Degrees of protection
IP20 (cabinet installation) / UL open: Standard enclosure. The drive
must be installed in a cabinet to fulfil the requirements for shielding
from contact.
IP20 / NEMA 1: Achieved with an option kit including a hood and a
connection box.
