3.1.1 Safety Instructions
See
for general safety instructions.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run
together can charge equipment capacitors even with the
equipment turned off and locked out. Failure to run
output motor cables separately or use screened cables
could result in death or serious injury.
•
run output motor cables separately, or
•
use screened cables
CAUTION
SHOCK HAZARD
The frequency converter can cause a DC current in the
PE conductor. Failure to follow the recommendation
below means that the RCD may not provide the
intended protection.
•
When a residual current-operated protective
device (RCD) is used for protection against
electrical shock, only an RCD of Type B is
permitted on the supply side.
Overcurrent protection
•
Additional protective equipment such as short
circuit protection or motor thermal protection
between frequency converter and motor is
required for applications with multiple motors.
•
Input fusing is required to provide short circuit
and overcurrent protection. If not factory-
supplied, the installer provides fuses. See
maximum fuse ratings in
VLT
®
DriveMotor FCP 106
and FCM 106 Operating Instructions
.
Wire Type and Ratings
•
All wiring must comply with local and national
regulations regarding cross section and ambient
temperature requirements.
•
Power connection wire recommendation:
minimum 75
°
C rated copper wire.
See
VLT
®
DriveMotor FCP 106 and FCM 106 Operating
Instructions
for recommended wire sizes and types.
3.1.2 Special Conditions
Electrical ratings
The frequency converter rating, shown on the nameplate,
is based on a typical 3-phase mains power supply within
the specified voltage, current and temperature range,
expected for most applications.
The frequency converters also support other special
applications, which affect the electrical ratings of the
frequency converter.
Special conditions which can affect the electrical ratings:
•
Single phase applications
•
High temperature applications which require
derating of the electrical ratings
•
Marine applications with more severe environ-
mental conditions.
Other applications can also affect the electrical ratings.
Consult the relevant sections in this manual and in the
VLT
®
DriveMotor FCP 106 and FCM 106 Design Guide
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 overcurrent and
short circuit protection
•
Selection of power cables (mains, motor,
brakeloadsharing, and relay)
•
Grid configuration (grounded delta transformer
leg, IT, TN, and so on)
•
Safety of low-voltage ports (PELV conditions).
Consult the relevant clauses in this manual and in the
VLT
