Danfoss vlt FC 102 Installation Guide

5.2 Electrical Requirements for Certications and Approvals
The standard conguration provided in this guide (drive
modules, control shelf, wire harnesses, fuses, and
microswitches) is UL and CE certied. The following
conditions must be met apart from the standard congu-
ration to obtain UL and CE regulatory approval
requirements. For a list of disclaimers, see
chapter 8.1 Disclaimer.
•
Use the frequency converter in a heated, indoor-
controlled environment. Cooling air must be
clean, free from corrosive materials, and
electrically conductive dust. See for specic limits.
•
Maximum ambient air temperature is 40 °C
(104 °F) at rated current.
•
The drive system must be assembled in clean air,
according to enclosure classication. To obtain UL
or CE certication regulatory approvals, drive
modules must be installed according to the
standard conguration provided in this guide.
•
Maximum voltage and current must not exceed
the values provided in chapter 7.1 Power-
dependent
Specications for the specied drive
conguration.
•
The drive modules are suitable for use on a
circuit capable of delivering not more than
100 kA rms symmetrical amperes at the drive
nominal voltage (600 V maximum for 690 V units)
when protected by fuses with the standard
conguration. Refer to chapter 5.4.1 Fuse Selection.
The ampere rating is based on tests done
according to UL 508C.
•
The cables located within the motor circuit must
be rated for at least 75 °C (167 °F) in UL-
compliant installations. The cable sizes have been
provided in chapter 7.1 Power-dependent Speci-
cations for the specied drive conguration.
•
The input cable must be protected with fuses.
Circuit breakers must not be used without fuses
in the U.S. Suitable IEC (class aR) fuses and UL
(class L or T) fuses are listed in chapter 5.4.1 Fuse
Selection. In addition, country-specic regulatory
requirements must be adhered to.
•
For installation in the U.S., branch circuit
protection must be provided according to the
National Electrical Code (NEC) and any applicable
local codes. To fulll this requirement, use UL-
classied fuses.
•
For installation in Canada, branch circuit
protection must be provided according to the
Canadian Electrical Code and any applicable
provincial codes. To fulll this requirement, use
the UL-classied fuses.
