Important notes
DANGER!
Risk of injury and risk of burns from dangerous voltage
Power terminals may also carry voltage in the switched-o state or when the motor is stopped
and may cause life-threatening cardiac arrhythmia and serious burns.
▶
Disconnect the product from the mains.
▶
Check that the power terminals are deenergized before starng work.
•
When working on energized products, comply with the applicable naonal accident
prevenon regulaons.
•
The electrical installaon must be carried out according to the appropriate regulaons
(e.g. cable cross-secons, fuses, PE connecon).
•
The manufacturer of the system or machine is responsible for adherence to the limits
required in connecon with EMC legislaon.
Second ground connecon on the motor
NOTICE
▶
According to standard EN 61800-5-1, an addional PE conductor is required if the leakage
current is greater than 3.5 mA for alternang current or greater than 10 mA for direct
current.
Please note the following:
•
Do not place the second terminal under the same terminal.
Addionally, consider at least one or more of the following:
•
The minimum PE conductor cross-secon is 10 mm
2
with Cu or 16 mm
2
with Al.
•
Applicaon of an addional protecve grounding conductor with the same cross-secon
as the original protecve grounding conductor.
•
Provide automac disconnecon of the mains in case of interrupon of the protecve
conductor.
Operaon on an external inverter
A max. pulse voltage amplitude of U
pk
= 1560 V at the motor terminals must not be exceeded.
Here, the minimum pulse rise me must be t
R
= 0.1 µs.
If it cannot be ruled out that the permissible voltage peaks will be exceeded or that the
minimum pulse rise me will not be reached, the following measures must be iniated:
•
Reducon of the DC-bus voltage (threshold for brake chopper voltage)
•
Use of lters, chokes
•
Use of special motor cables
Preparaon
EMC-compliant wiring
The EMC-compliant wiring is described in detail in the documentaon of the
Lenze inverters.
