1.2 Electrical Safety - General
Warning
The voltages used in the EV3200 door control inverter (for
short, controller) can cause severe electrical shock and/or
burns, and could be lethal. Extreme care is necessary at all
times when working with or adjacent to the inverter.
Specific warnings are given at the relevant places in this
guide.
1.3 System Design And Safety Of
Personnel
The inverter is intended as a component for inverter system.
If installed incorrectly, the inverter may present a safety
hazard. The inverter uses high voltages and currents,
carries a high level of stored electrical energy, and is used
to control equipment that can cause injury.
System design, installation, commissioning and
maintenance must be carried out by personnel who have
the necessary training and experience. They must read this
safety information and this guide carefully.
The supply must be disconnected by an approved electrical
isolation device before gaining access to the electrical
connections.
Careful consideration must be given to the function of the
inverter which might result in a hazard, either through its
intended behavior or through incorrect operation due to a
fault. In any application where a malfunction of the inverter
or its control system could lead to or allow damage, loss or
injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for
example, an over-speed protection device in case of failure
of the speed control, or a fail-safe mechanical brake in case
of loss of motor braking.
1.4 Motor
Ensure the motor is installed in accordance with the
manufacturer's recommendations.
Ensure the motor shaft is not exposed.
If it is intended to use the capability of an inverter to run a
motor at speeds above its designed maximum, it is strongly
recommended that the manufacturer be consulted first.
Low speeds may cause the motor to overheat because the
cooling fan becomes less effective. The motor should be
fitted with a protection thermistor. If necessary, an electric
force vent fan should be used.
It is essential that the correct value is entered into F6.03,
motor rated current. This affects the thermal protection of
the motor.
1.5 Adjusting Parameters
Some parameters have a profound effect on the operation
of the inverter. They must not be altered without careful
consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due
to error or tampering.
1.6 Electrical Installation
1.6.1 Electric Shock Risk
The voltages present in the following locations can cause
severe electric shock and may be lethal:
AC supply cables and connections
DC and brake cables, and connections
Output cables and connections
Many internal parts of the inverter, and external option
units
Unless otherwise indicated, control terminals are single
insulated and must not be touched.
1.6.2 Isolation Device
The AC supply must be disconnected from the inverter
using an approved isolation device before any cover is
removed from the inverter or before any servicing work is
performed.
