General installation regulations
NOTICE
Destruction of the drive!
Incorrect operation or incorrect control can destroy the drive.
1. The F-CEVF is equipped with an
asynchronous motor
.
2. Operating on a grid with a non-earthed start point is not permitted.
The electrical installation must correctly fulfil the requirements of IEC 60204-1,
IEC 60204-11 and IEC 61010-1 in accordance with the ambient and operating
conditions.
The electrical installation must also be implemented according to the applicable
national, local and plant-specific stipulations, as well as the requirements of the
power supply company.
The conditions at the operating site must comply with the information on the Rat-
ing plate [
ڰ
12]. The following conditions are permitted during mains operation:
▪
±15% variation in voltage from EN 60034-1 without loss of performance
(range A) for standard motors
▪
±5% variation in voltage without loss of performance according to EN 60034-1
(range A) for IE3 motors
▪
±10% variation in voltage with a loss of performance according to EN 60034-1
(range A) for IE3 motors
▪
±2% deviation in frequency
▪
The electrical data are provided on the rating plate (item M, [
ڰ
12])
The electrical installation must:
▪
Be correctly attached and protected.
▪
Be kept away from hot surfaces.
▪
Be electrically isolated to a sufficient degree.
▪
Be constructed and fitted in such a way that the following faults do not lead to
damage:
– short circuits
– mechanical impacts
– power supply failures or surges
– electromagnetic fields
– earth connections
The electrical equipment and control must not put the protective devices of the
drive system and the motor protection (e.g. PTC resistor, bimetal switch, frequen-
cy inverter current limit) out of operation.
When the power supply fails or surges, the control must prevent the F-CEVF from
remaining in operation or starting up.
Protective devices and switches must fulfil the failure safety conditions.
Overcurrent protection
The power supply of the motor must be equipped with an overcurrent protection
device (e.g. a motor protection circuit breaker) according to IEC 60204-1, 7.2.
Separator for the electrical energy supply
A separator for the electrical energy supply must be:
▪
Provided according to IEC 60204-1, 5.3 and 5.5.
▪
Clearly and visibly labelled.
