I n sta l li ng the Inve rt e r
Connecting CAN bus
1. Unscrew the cable fi tting.
2. Thread the connection cables through the cable fi tting.
3. Connect the connection cable to the corresponding connection terminals.
4. Connect the following to all inverters
• CAN H with CAN H and
• CAN L with CAN L and
• GND with GND (see Figure 20 on page 29)
5. Tighten the cable fi tting.
6. For correct signal transmission, the fi rst 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 Figure 17 on page 28)
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 fl ashes until a feed-in phase
or SYM bus address has been entered. (See Section 9.5 on page 49)
10. The maximum permitted asymmetry must still be entered so that symmetrisation can take place properly. In
some countries (DE, IT) this value is preconfi gured in accordance with the applicable directive and does not
normally need to be changed. (Table 3 on page 24)
NOTE
A maximum of 30 inverters may be connected when using one-phase inverters to be symmetrised!
(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-
breakers 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 fi tting.
2. Thread the connection cables through the cable fi tting.
3. Connect wire A (+) to the terminal marked "EVU+" on the fi rst inverter via the "DO1"
terminal of the Powador-protect.
4. Connect wire B (-) to the terminal marked "EVU-" on the fi rst 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 fi tting.
7. After commissioning: Activate the support for the Powador protect in the
parameter menu under the "Powador-protect" menu item.
