Danfoss VLT FC 300 Operating Instructions

24 V DC Power Supply
•
5 A, 120 W, 24 V DC
•
Protected against output over-current, overload,
short circuits, and over-temperature
•
For powering customer-supplied accessory
devices such as sensors, PLC I/O, contactors,
temperature probes, indicator lights, and/or other
electronic hardware
•
Diagnostics include a dry DC-ok contact, a green
DC-ok LED, and a red overload LED
External Temperature Monitoring
Designed for monitoring temperatures of external system
components, such as the motor windings and/or bearings.
Includes eight universal input modules plus two dedicated
thermistor input modules. All ten modules are integrated
into the frequency converter’s safe-stop circuit and can be
monitored via a fieldbus network (requires the purchase of
a separate module/bus coupler).
Universal inputs (8)
Signal types:
•
RTD inputs (including Pt100), 3-wire or 4-wire
•
Thermocouple
•
Analog current or analog voltage
Additional features:
•
One universal output, configurable for analog
voltage or analog current
•
Two output relays (N.O.)
•
Dual-line LC display and LED diagnostics
•
Sensor lead wire break, short-circuit, and incorrect
polarity detection
•
Interface setup software
Dedicated thermistor inputs (2)
Features:
•
Each module capable of monitoring up to six
thermistors in series
•
Fault diagnostics for wire breakage or short-
circuits of sensor leads
•
ATEX/UL/CSA certification
•
A third thermistor input can be provided by the
PTC Thermistor Option Card MCB 112, if
necessary

Electrical Installation
3.3.1 Transformer Selection
The frequency converter must be used with a 12-pulse
isolation transformer.
3.3.2
Power Connections 12-Pulse Drives
Cabling and Fusing
NOTE
Cables General
All cabling must comply with national and local
regulations on cable cross-sections and ambient
temperature. UL applications require 75° C copper
conductors. 75° and 90° C copper conductors are thermally
acceptable for the frequency converter to use in non UL
applications.
The power cable connections are situated as in
Illustration 3.21. Dimensioning of cable cross section must
be done in accordance with the current ratings and local
legislation. See 5.1 General Specifications for details.
For protection of the frequency converter, the
recommended fuses must be used or the unit must be
with built-in fuses. Recommended fuses can be seen in
3.3.13 Fuses . Always ensure that proper fusing is made
according to local regulation.
The mains connection is fitted to the mains switch if this is
included.

NOTE
The motor cable must be screened/armoured. If an
unscreened/unarmoured cable is used, some EMC
requirements are not complied with. Use a screened/
armoured motor cable to comply with EMC emission
specifications. For more information, see EMC Specifications
in the Design Guide, MG11BXYY and the FC 300 Design
Guide, MG33BXYY.
See 5.1 General Specifications for correct dimensioning of
motor cable cross-section and length.
