WARNING
Electric shock or short circuit due to improper connections
Improper connections have high risks of electric shock and short circuit, which will
jeopardize personal safety and equipment.
•
The drive must be directly connected with the motor. It is not permissible to connect a
capacitor, inductor or filter between them.
•
The line supply voltage must be within the allowable range (refer to the drive rating
plate). Never connect the line supply cable to the motor terminals U, V, W or connect the
motor power cable to the line input terminals L1, L2, L3.
•
Never wire up the U, V, W terminals in an interchanged phase sequence.
•
If the CE marking for cables is mandatory in some cases, the motor power cable, line
supply cable and brake cable used must all be shielded cables.
•
For terminal box connection, make sure that the clearances between non-insulated live
parts are at least 5.5 mm.
•
Route signal cables and power cables separately in different cable conduits. The signal
cables shall be at least 10 cm away from the power cables.
•
Cables connected may not come into contact with rotating mechanical parts.
6.4.2
Connecting-up information
Observe data on the motor rating plate data and circuit diagram in the motor terminal box.
Use sufficiently dimensioned connection cables.
Note
System compatibility for connection
System compatibility is guaranteed only if shielded power cables are used and the shield is
conductively bonded over a large area to the metal motor terminal box (with a metal EMC
cable gland).
Shields must be incorporated in the protective grounding concept. Protective ground should
be connected to conductors that are open-circuit and that are not being used and also
electrical cables that can be touched. (Open-circuit cables result in capacitive
charges/discharges.)
Use EMC cable glands for fixed cable entries. The cable glands are screwed into the threaded
holes on the terminal box.
Openings that are not used must be closed with an appropriate metal cap.
Internal equipotential bonding
The equipotential bonding between the grounding terminal in the terminal box enclosure
and the motor housing is established through the terminal box fixing screws. The contact
locations underneath the screw/bolt heads are bare and are protected against corrosion.
Equipotential bonding between the terminal box cover and the terminal box enclosure can be
provided by the normal fixing screws of the cover.
