Connecting CAN bus
1. Unscrew the cable fitting.
2. Thread the connection cables through the cable fitting.
3. Connect the connection cable to the corresponding connection terminals.
4. Connect as follows to all inverters
• CAN H with CAN H and
• CAN L with CAN L and
• GND with GND (see Bild 20 auf Seite 26)
5. Tighten the cable fitting.
6. For correct signal transmission, the first and last devices in the group of three
must have the "Term CAN" terminating switch set to ON.
The terminating switch "Term CAN" must be set to OFF on the middle inverter.
7. This termination does not depend on the manner of cabling that is used. The switch is found on the
board next to the terminal block. (See Bild 17 auf Seite 24)
8. All inverters of a group must be assigned a unique SYM bus address within the range of 1 to 32.
9. Enter feed-in phase for every inverter into which the inverter feeds. The red LED flashes until a feed-in phase
or SYM bus address has been entered. (See Section 9.5 auf Seite <?>)
10. If necessary, the maximum permitted asymmetry must still be entered so that symmetrisation can take place
properly. In some countries (DE, IT) this value is preconfigured in accordance with the applicable directive and
does not normally need to be changed. (Tabelle 5 auf Seite 21)
NOTE
A maximum of 30 inverters may be connected when using one-phase inverters to be synchronised!
(Number of inverters divisible by 3!)
A new inverter group must then be formed.
7.4.2 Connecting "Inverter off" digital input (optional)
NOTE
The Powador-protect digital output can only be used with suitable KACO inverters. When using
devices from other manufacturers or in combination with KACO inverters, bus coupler circuit-break-
ers as a minimum must be used for shutting down devices from other manufacturers.
Connecting and activating "Inverter off" digital input
↻ Can only be used with suitable KACO inverters.
1. Unscrew the cable fitting.
2. Thread the connection cables through the cable fitting.
3. Connect wire A (+) to the terminal marked "EVU+" on the first inverter via the "DO1"
terminal of the Powador-protect.
4. Connect wire B (-) to the terminal marked "EVU-" on the first inverter via the "GND"
terminal of the Powador-protect.
5. Connect the other inverters to one another as follows:
– wire A (+) to wire A (+) and wire B (-) to wire B (-).
6. Tighten the cable fitting.
7. After commissioning: Activate the support for the Powador protect in the parameter
menu under the "Powador-protect" menu item.
