5.5 Preparing the Connection Cables for Connection to
Multi-Pole Plugs
Always proceed as follows to prepare connection cables for connection to multi-pole plugs.
Procedure:
1. Trim 4 cm of the cable sheath at the end of the connection cable to be attached to the multi-pole
plug.
2. Trim unused insulated conductors flush with the cable sheath.
3. Strip off the conductor insulation by 6 mm.
5.6 Connecting the Ripple Control Receiver
Additionally required material (not included in the scope of delivery):
☐ One ripple control receiver with four outputs (see figure 5)
☐ One or two connection cables (see Section 5.2 "Cable Requirements", page 14)
Requirements:
☐ The connection cable must have been prepared for connection to the multi-pole plug (see
Section 5.5 "Preparing the Connection Cables for Connection to Multi-Pole Plugs", page 19).
☐ The enclosure opening on the inverter must be prepared (see Section 5.4 "Preparing the
Enclosure Opening on the Inverter", page 18).

Duplicate terminals for ripple control receiver
The ripple control receiver can be connected either to pins 1 to 5 or to pins 14 to 18.
The pins 1/18, 2/17, 3/16, 4/15 and 5/14 are each bridged so that a loop through of the
ripple control receiver signals is possible.
