Cable Requirements; Grounding; Motor Connection; Connect Fcp 106 To Motor - Danfoss VLT DriveMotor FCP 106 Operating Instructions Manual

Electrical Installation
To ensure EMC-compliant electrical installation, observe
these general points:
•
Use only screened motor cables and screened
control cables.
•
Connect the screen to ground at both ends.
•
Avoid installation with twisted screen ends
(pigtails), since this type of installation ruins the
4 4
screen effect at high frequencies. Use the cable
clamps provided instead.
•
Ensure the same potential between frequency
converter and ground potential of the PLC.
•
Use star washers and galvanically conductive
installation plates.

4.4 Cable Requirements

All cabling must comply with national and local regulations
on cable cross-sections and ambient temperature. Copper
or aluminium conductors are required (75 °C (167 °F)
(recommended). For cable specifications, refer to
chapter 7.6 Cable Specifications.

4.5 Grounding

When connecting the FCP 106 to a third-party motor,
ensure protective bonding:
•
Ensure metal contact between the frequency
converter and the motor, see Illustration 4.5.
•
Mount an extra ground wire on the adapter plate.
•
Mount an extra ground wire on the motor.

4.6 Motor Connection

4.6.1 Connect FCP 106 to Motor

NOTICE
To avoid damage to equipment, before mounting the
FCP 106 on the motor:
•
Observe cooling clearances specified in
Table 7.1.
•
Observe screw clearances listed in Table 7.2.
NOTICE
RISK OF DAMAGE
Screws extending too far into the enclosure or too far
above the adapter plate pose a risk of damage to motor
or frequency converter.
To connect the FCP 106 to the motor, follow the instal-
lation steps shown in Table 4.1 and Illustration 4.5.

1) Contacts from other manufacturers, and contacts made with equal
or better electrical conductivity and plating, are also suitable if they
fulfil the mechanical and electrical requirements.
The FCP 106 is now mounted onto the motor. The
combined unit is known as the DriveMotor.

Mount PE clamp to motor connector and connect crimp
PE terminal to wire.
Mount the gasket between the motor and adapter plate.
See chapter 3.3.2 Prepare Gasket.
Pull motor phases and thermistor wires through the neck
of the adapter plate.
Mount the adapter plate onto the motor using 4 screws.
•
Insert guide pins into 2 of the screw holes, before
lowering the adapter plate into position. Remove the
guide pins when mounting screws.
•
Ensure that metallic contact is established between
the adapter plate and the motor, via the screws.
Mount motor connector gaskets onto the neck of the
adapter plate.
Click the terminals into the motor connector.
•
Mount the 3 motor phases.
•
Mount the 2 thermistor wires.
•
Mount PE connector.
•
For correct installation, refer to terminal numbers
printed on the motor connector.
NOTICE
The thermistor is not galvanically isolated.
Interchanging the thermistor wires with the motor
wires may permanently damage the frequency
converter.
Click motor connector into the neck of the adapter plate.
Position the FCP 106 on adapter plate.
Fasten the FCP 106 to adapter plate using 4 screws.
