Safety Information
Only qualied, 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 qualied 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 specied 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 DC-
link 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.

Assembling the Current Sensor Cylinder Busbars in D1h/D3h/D5h/D6h Drives
WARNING
NOMEX SLEEVES REQUIRED
The Nomex sleeves are required to maintain proper electrical protection. Failure to install the Nomex sleeves can result in
personal injury or equipment damage.
•
Do not discard the Nomex sleeves.
Use the following steps to assemble the current sensor cylinder busbars in D1h/D3h/D5h/D6h drives. Refer to Illustration 1.2.
1. Place the 3 Nomex sleeves over the cylinder busbars,
1 per busbar. Place the sleeve with the red marking
on the short busbar.
2. Insert 3 M6x90 screws through the center of the
busbars and place the busbar mounting frame, 1
screw per busbar. The busbar with the red marking is
the V busbar and is mounted in the middle.
3. Retain 3 M6x16 screws to fasten the busbar
mounting frame in the drive when installing the
current sensors. The cylinder busbars are inserted
through the centers of the current sensors. Refer to
300 A Current Sensor Kit for D1h/D3h/D5h/D6h Drives
installation instruction.
