Connection box kit

The inverter module is supplied with a connection box kit containing the following
items:
• back plate
• cover
• 3 clamps
• lug terminals (frame sizes R2i and R3i only)
• screws.
The kit also contains a shroud for covering the relay outputs of the RMIO board.

Cable connection procedure

Refer to the diagram below.
1. Insert the hooks of the connection box back plate to the two corresponding slots
in the bottom plate of the inverter module.
2. Fasten the back plate to the module frame with two screws.
3. Strip off the plastic sheaths of the input (DC) cable (if of shielded type) and motor
cables under the cable clamps. Fasten the clamps onto the stripped part of the
cable.
4. (Frame sizes R2i and R3i) Crimp a lug terminal (supplied in the connection box
kit) onto the twisted shields of the cables.
(All frame sizes) Connect the shields to the grounding terminals.
5. Connect the conductors of the input (DC) cable to the UDC+ and UDC– terminals
and the phase conductors of the motor cable to the U2, V2 and W2 terminals.
6. Secure the cables outside the unit mechanically.
7. Connect the control cables as described in section
8. Fasten the cover to the back plate with two screws.
