Electrical connection WPF...MS (single phase) with WPAB
The WPAB can be installed inside the domestic distribution panel to limit the starting current of the TTF...MS. Implement the wiring in accordance with
Fig. 11. The WPAB limits the starting current to the values stated in the specification.
!
When connecting the WPAB, remove the jumper between R and RC.
!
When using the WPAB, L (terminal X3) on the compressor and L (terminal X4) on the controller must use the same phase, and this should be
protected by an RCD
