2.1.6 Special Conditions
Electrical ratings:
The rating indicated on the nameplate (Illustration 2.1) of the frequency converter is based on a typical 3-phase mains
power supply, within the specified voltage, current and temperature range, which is expected to be used in most
applications.
The frequency converters also support other special applications, which affect the electrical ratings of the frequency
converter.
Special conditions which affect the electrical ratings might be:
□
Single phase applications
□
High temperature applications which require de-rating of the electrical ratings
□
Marine applications with more severe environmental conditions.
Other applications might also affect the electrical ratings.
Consult the relevant clauses in these instructions and in the
AKD102 Design Guide, MG.11.Mx.yy
for information about the
electrical ratings.
Installation requirements:
The overall electrical safety of the frequency converter requires special installation considerations regarding:
□
Fuses and circuit breakers for over-current and short-circuit protection
□
Selection of power cables (mains, motor, brake, loadsharing and relay)
□
Grid configuration (IT,TN, grounded leg, etc.)
□
Safety of low-voltage ports (PELV conditions).
Consult the relevant clauses in these instructions and in the
AKD102 Design Guide
for information about the installation
requirements.
2.1.7 Safe Stop of the Frequency Converter
For versions fitted with a Safe Stop terminal 37 input, the frequency converter can perform the safety function
Safe Torque
Off
(As defined by draft CD IEC 61800-5-2) or
Stop Category 0
(as defined in EN 60204-1).
It is designed and approved suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe
Stop. Prior to integration and use of Safe Stop in an installation, a thorough risk analysis on the installation must be carried
out in order to determine whether the Safe Stop functionality and safety category are appropriate and sufficient. In order to
install and use the Safe Stop function in accordance with the requirements of Safety Category 3 in EN 954-1, the related
information and instructions of the
AKD102 Design Guide MG.11.MX.YY
must be followed! The information and instructions of
the Operating Instructions are not sufficient for a correct and safe use of the Safe Stop functionality!
