Procedure:
1. Insert one end of the cable in inverter 1 and the other end in inverter 2. Each cable must be
routed through the seal and the cable gland of the inverter.
2. Connect a six-pole plug to each end of the cable as follows:
• Release the required conductor inlets of the plug using a screwdriver.
• Insert the insulated conductors into the conductor inlets. Make sure that the noted conductor
colors correspond to the pin assignment of the module.
3. In inverter 1, connect the six-pole plug to the free terminal for the ripple control receiver.
Observe the pin assignment.
4. In inverter 2, connect the six-pole plug to one of the terminals for the ripple control receiver.
Observe the pin assignment.
5. Fasten the swivel nut of the cable gland on both inverters hand-tight. Ensure that the cable is
securely in place and that the enclosure opening of the inverter is tightly sealed.
6. On both inverters, flip down the display and fasten the display screw hand-tight.
7. Close and commission both inverters (see inverter manual).
