Field Installation Of Options; Installation Of Mains Shield For Frequency Converters; Frame Size F Panel Options - Danfoss VLT AQUA Drive FC 200 Operating Instructions Manual

How to Install
4.3.8 IP21 Drip Shield Installation (Frame
size D)
To comply with the IP21 rating, a separate drip shield is
to be installed as explained below:
•
Remove the two front screws
•
Insert the drip shield and replace screws
•
Torque the screws to 5.6 Nm (50 in-lbs)
NOTE
Drip shield is necessary on both filter and drive section.

4.5 Frame Size F Panel Options

Space Heaters and Thermostat
Mounted on the cabinet interior of frame size F frequency
converters, space heaters controlled via automatic
thermostat help control humidity inside the enclosure,
VLT AQUA Low Harmonic Drive Operating Instructions
extending the lifetime of frequency converter components
in damp environments. The thermostat default settings
turn on the heaters at 10° C (50° F) and turn them off at
15.6° C (60° F).
Cabinet Light with Power Outlet
A light mounted on the cabinet interior of frame size F
frequency converters increase visibility during servicing
and maintenance. The housing the light includes a power
outlet for temporarily powering tools or other devices,
available in two voltages:
Transformer Tap Setup
If the Cabinet Light & Outlet and/or the Space Heaters &
Thermostat are installed Transformer T1 requires it taps to
be set to the proper input voltage. A 380-480/500 V
380-480 V frequency converter will initially be set to the
525 V tap and a 525-690 V frequency converter will be set
to the 690 V tap to ensure no over-voltage of secondary
equipment occurs if the tap is not changed before it is
applied. See the table below to set the proper tap at
terminal T1 located in the rectifier cabinet. For location in
the frequency converter, see Illustration 4.36.

NAMUR Terminals
NAMUR is an international association of automation
technology users in the process industries, primarily
chemical and pharmaceutical industries in Germany.
Selection of this option provides terminals organized and
labeled to the specifications of the NAMUR standard for
frequency converter input and output terminals. This
requires MCB 112 PTC Thermistor Card and MCB 113
Extended Relay Card.
RCD (Residual Current Device)
Uses the core balance method to monitor ground fault
currents in grounded and high-resistance grounded
systems (TN and TT systems in IEC terminology). There is a
pre-warning (50% of main alarm set-point) and a main
alarm set-point. Associated with each set-point is an SPDT
alarm relay for external use. Requires an external "window-
type" current transformer (supplied and installed by
customer).
