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 earth at both ends.
•
Avoid installation with twisted screen ends
(pigtails), since this ruins the screen effect at high
frequencies. Use the cable clamps provided
instead.
•
Ensure the same potential between frequency
converter and ground potential of 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 required,
(75 °C) 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 the frequency converter is grounded at minimum 2
points:
•
Ensure metal contact between adapter plate and
motor.
•
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
Risk of damage to motor or frequency converter exists if
screws extend too far into the enclosure or too far above
the adapter plate.

Operating Instructions
To connect the FCP 106 to the motor, follow the instal-
lation steps shown in Table 4.1 and Illustration 4.4.
Step Description
1 Mount motor phases and thermistor wires in crimp
terminals. Note: Crimp order numbers from manufacturer
TE (AMP standard power timer contacts):
•
•
•
2 Mount PE clamp to motor connector and connect crimp
PE terminal to wire.
3 Mount the gasket between the motor and adapter plate.
See chapter 3.3.2 Prepare Gasket
4 Pull motor phases and thermistor wires through the neck
of the adapter plate.
5 Mount the adapter plate onto the motor using 4 screws.
•
•
6 Mount motor connector gaskets onto the neck of the
adapter plate.
7 Click the terminals into the motor connector.
•
•
•
•
NOTICE
The thermistor is not galvanically isolated.
Interchanging the thermistor wires with the
motor wires may permanently damage the
frequency converter.
8 Click motor connector into the neck of the adapter plate.
9 Position FCP 106 on adapter plate.
10 Fasten the FCP 106 to adapter plate using 4 screws.
Table 4.1 Installation steps as shown in Illustration 4.4
The FCP 106 is now mounted onto the motor. The
combined unit is known as the DriveMotor.

Insert guide pins into 2 of the screw holes, before
lowering the adapter plate into position. Remove the
guide pins when mounting screws.
Ensure metallic contact is established between the
adapter plate and the motor, via the screws.
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.
