Lenze 13466185 EDBSW03 v5 11
Installation
3.2.4 Control terminals
Terminal Data for control connections (printed in bold = Lenze setting)
CAN_GND CAN earth ground
For reliable communication make sure terminal
CAN_GND is connected to CAN network
GND/common. If only two wires are used
(CAN_H and CAN_L) in the network, connect
CAN_GND to chassis/earth ground.
CAN_L CAN low If controller is located at either end of the
network, a terminating resistor (120Ω typical)
should be connected across CAN_L and CAN_H
CAN_H CAN high
28 Digital input Start/Stop
LOW = Stop ( OFF )
HIGH = Run Enable

Fault (TRIP)
AC 250 V / 3 A
DC 24 V / 2 A … 240 V / 0.22 A
K14
LOW = 0 … +3 V, HIGH = +12 … +30 V
Protection against contact
• All terminals have a basic isolation (single insulating distance)
• Protection against contact can only be ensured by additional measures i.e. double insulation
