NOTICE
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, cur-
rent may flow across the shielding. This current may damage the device.
► Connect the devices to a potential equalization rail to equalize the poten-
tial.
► If both devices have different potentials, only connect the CAN bus cable
shielding to one device.
Variant 1: The connected devices share the same potential
1. Connect all devices to a potential equalization rail to equalize the poten-
tial.
2. Connect the CAN bus cable shielding to all connected devices.
Variant 2: The connected devices have different potential levels
Note that the shielding is less effective with this variant.
1. Connect the CAN bus cable shielding
to just one
device.
2. Connect the wires of the shielded CAN bus cable in accordance with the
connection diagram supplied.
6.4.4.2 Mounting terminating resistor of CAN bus
If you want to operate the device in parallel operation, you need to mount a
120 Ω terminating resistor at both ends of the CAN bus between CAN_L and
CAN_H (see supplied connection diagram).
6.4.5 Wiring voltage measurement/current measurement UI
You must fuse the voltage measurement circuit in accordance with the con-
ductor cross section used. You can use the following fuse types:
Miniature circuit breaker
Safety fuse
Standard
IEC 60947-2
IEC 60269
Rated voltage
110/230 V (L-N)
Rated current
1.6 mA...16 A
