1.1.1 Identifying the Power Rating
To nd the drive power rating, use the following steps:
1. Obtain the following information from the
nameplate, which is on the drive. Refer to
Illustration 1.1.
•
Product group and drive series
(characters 1–6)
•
Power rating (characters 7–10)
•
Voltage rating (phases and mains)
(characters 11–12)
2. Determine if the power rating is in Ta ble 1.1.

1.2 Safety Information
Only
qualied,
Danfoss-authorized personnel are allowed to
install the parts described in these installation instructions.
Handling of the drive and its parts must be done in
accordance with the corresponding operating guide.
WARNING
ELECTRICAL SHOCK HAZARD
VLT® FC series drives contain dangerous voltages when
connected to mains voltage. Improper installation, and
installing or servicing with power connected, can cause
death, serious injury, or equipment failure.
To avoid death, serious injury, or equipment failure:
•
Only use
qualied
electricians for the installation.
•
Disconnect the drive from all power sources before
installation or service.
•
Treat the drive as live whenever the mains voltage
is connected.
•
Follow the guidelines in these instructions and local
electrical safety codes.
WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain
charged even when the drive is not powered. High voltage
can be present even when the warning LED indicator lights
are
o.
Failure to wait the
specied
time after power has
been removed before performing service or repair work can
result in death or serious injury.
•
Stop the motor.
•
Disconnect AC mains and remote DC-link power
supplies, including battery back-ups, UPS, and DClink connections to other drives.
•
Disconnect or lock PM motor.
•
Wait for the capacitors to discharge fully. The
minimum waiting time is 20 minutes.
•
Before performing any service or repair work, use
an appropriate voltage measuring device to make
sure that the capacitors are fully discharged.
NOTICE
ELECTROSTATIC DISCHARGE
Follow proper ESD precautions to prevent damage to
sensitive components.

1.3 Disassembly Instructions
NOTICE
To make the disassembly/reassembly process easier, use
these general guidelines:
1. Follow the disassembly instructions for each
component.
2. Place the component together with the removed
fasteners.
3. Replace old component with the new component
provided in the kit.
4. If any fasteners are stripped or lost, replace with
similar fastener from the kit.
5. Follow the assembly instructions to replace and
secure each component.
1.3.1 General Torque Tightening Values
Use a torque wrench to ensure that correct torque is applied.
Incorrect torque can cause electrical connection problems. For
fastening hardware described in this instruction, use the values
listed in Tab le 1.4 to Tab le 1.6 except where noted in the
procedures.
