Danfoss vlt FC 102 Installation Guide

WARNING
LEAKAGE CURRENT HAZARD (>3.5 mA)
Leakage currents exceed 3.5 mA. Failure to ground the
drive system properly can result in death or serious
injury. Follow national and local codes regarding
protective earthing of equipment with a leakage current
>3.5 mA. Frequency converter technology implies high
frequency switching at high power. This switching
generates a leakage current in the ground connection. A
fault current in the drive system at the output power
terminals sometimes contain a DC component, which can
charge the lter capacitors and cause a transient ground
current. The ground leakage current depends on various
system congurations including RFI ltering, shielded
motor cables, and drive system power.
If the leakage current exceeds 3.5 mA, EN/IEC 61800-5-1
(Power Drive System Product Standard) requires special
care.
Grounding must be reinforced in 1 of the following ways:
•
Ensure the correct grounding of the equipment
by a certied electrical installer.
•
Ground wire of at least 10 mm
2
(6 AWG).
•
Two separate ground wires, both complying
with the dimensioning rules.
See EN 60364-5-54 § 543.7 for further information.
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment
can result in death or serious injury.
•
Ensure that only trained and qualied personnel
perform the installation.
•
Ensure that electrical work conforms to national
and local electrical codes.
•
Follow the procedures in this document.
WARNING
DISCONNECT POWER BEFORE SERVICING
Sometimes during installation, AC mains power is
applied but then must be disconnected to change the
line connections. Failure to follow these steps can result
in death or serious injury.
•
Disconnect the frequency converters from the
AC mains, 230 V supply, and motor lines.
•
After the lines have been disconnected, wait 20
minutes for the capacitors to discharge.
WARNING
HEAVY LOAD
Unbalanced loads can fall and loads can tip over. Failure
to take proper lifting precautions increases risk of death,
serious injury, or equipment damage.
•
Never walk under suspended loads.
•
To guard against injury, wear personal
protective equipment such as gloves, safety
glasses, and safety shoes.
•
Be sure to use lifting devices with the
appropriate weight rating. The lifting bar must
be able to handle the weight of the load.
•
The load’s center of gravity may be in an
unexpected location. Failure to locate the center
of gravity correctly, and position the load
accordingly before lifting the load, can cause
the unit to fall over or tilt unexpectedly during
lifting and transport.
•
The angle from the top of the drive module to
the lifting cables has an impact on the
maximum load force on the cable. This angle
must be 65° or greater. Attach and dimension
the lifting cables properly.
