Page 37: General Notes
Electrical installation 37 WARNING! The busbars inside the cabinet of liquid-cooled drives are partially coated. Measurements made through the coating are potentially unreliable, so only measure at uncoated portions. Note that the coating does not constitute a safe or touch-proof insulation. Install temporary grounding as required by the local regulations.
Page 38: Measuring The Insulation
Use a measuring voltage of 1000 V DC. The insulation resistance of an ABB motor must be more than 100 Mohm (reference value at 25 °C [77 °F]). For the insulation resistance of other motors, refer to the manufacturer’s instructions.

Electrical installation 41 Connecting the cables This section describes the power cable connecting procedure for a bottom cable entry with the standard cable entry plate. The standard cable entry plate has conductive sleeves for the 360° grounding of the cable shields. For Rotex cable entry plate (option +H394) and cable gland plate (option +H358), refer to the manufacturer's instructions.
Page 42 42 Electrical installation conductors. Twist the shield to form a PE conductor, and mark it with yellow-green tape or heat-shrink tubing. For each cable, attach cable lugs at the end of the PE conductor (twisted shield) and phase conductors. For each cable, attach the conductive sleeve to the bare cable shield with a cable tie.
Page 43: Installing The Shrouding And Connecting The Motor
Electrical installation 43 Installing the shrouding and connecting the motor Install any shrouding removed earlier and close the cubicle doors. At the motor, connect the cables according to instructions from the motor manufacturer. Pay special attention to the phase order. For minimum radio-frequency interference, ground the cable shield 360 degrees at the lead-through of the motor terminal box, or ground the cable by twisting the shield so that the flattened shield is wider than 1/5 of its length.
Page 44: Frame R8I And Multiples - Connecting The Motor Cables (Units Without Common Motor Terminal Cubicle Or Sine Output Filter)
44 Electrical installation Frame R8i and multiples – Connecting the motor cables (units without common motor terminal cubicle or sine output filter) On units without a common motor terminal cubicle or a sine output filter, the motor cables connect to busbars located in the inverter module cubicles. To access the terminals, the cooling fans and other equipment in front of the terminals must be removed from the cubicle.
Page 45: Motor Connection Diagram (With Option +H366)
Electrical installation 45 Inverter unit cubicle(s) Motor connection diagram (with option +H366) ￭ With option +H366, the output busbars of the inverter modules within the same cubicle are connected by bridging busbars. The bridging balances the motor current between the modules, which allows more cabling options. For example, it is possible to use a number of cables that could not otherwise be evenly distributed between the inverter modules.
Page 46: Procedure
46 Electrical installation • In case of two inverter cubicles of two modules, connect the same number of cables to each cubicle. • In case of one inverter cubicle with three modules and another with two, each cubicle requires a number of cables proportional to the number of modules within. For example, connect three out of five (or six out of ten, etc.) cables to the cubicle with three modules, the remaining two out of five (four out of ten) cables to the cubicle with two modules.
Page 47 Electrical installation 47 IP54 cabinet: Remove the rear horizontal cable support bracket and the cable entry plate. IP54 cabinet: Remove a sealing grommet from the cable entry plate for each cable. Cut hole into the rubber grommet and move it onto the cable. Put the cables inside the cabinet through the cable entry plate.
