4.1 Electrical connection
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.
4.2 cUL
Overcurrent protection provide overload protection to avoid overheating of the cables in the installation. Over-
current protection must always be carried out according to local and national regulations. Suitable for use on a
circuit capable of delivering not more than 5,000 rms symmetrical amperes, 480volt maximum. Circuit breakers
must be designed for protection in a circuit capable of supplying a maximum of 10,000 Arms (symmetrical), 480
V maximum; or the value rated on the individual circuit breaker.
For UL Compliance Use the breakers or fuses listed below in the table to ensure compliance with UL or IEC
61800-5-1. Circuit breakers must be designed for protection in a circuit capable of supplying a maximum of
10,000 Arms (symmetrical), 480 V maximum. In the event of malfunction, failure to follow the protection recom-
mendation may result in damage to the drive / frequency converter. Circuit breaker must comply with UL 489.

4.3 Mains supply dimensioning relative to harmonic distortion
LPC motor controllers function like any other electronic power converter by converting AC to DC. As this conver-
sion produces a non-sinusoidal current, the mains supply for the motor controller is affected by harmonic distor-
tion.
The electrician or the user of the equipment shall ensure, if necessary by contacting the supply company, that
the equipment is connected to a correctly dimensioned mains supply.
