1. SAFETY
1.4 EARTHING AND EARTH FAULT PROTECTION
The AC drive must always be earthed with an earth conductor that is connected to the earth terminal that is identified with the
symbol . Not using an earth conductor can cause damage to the drive.
The touch current of the drive is more than 3.5 mA AC. The standard EN 61800-5-1 tells that 1 or more of these conditions for
the protective circuit must be true.
The connection must be fixed.
a) The protective earth conductor must have a cross-sectional area of minimum 10
㎟
Cu or 16
㎟
Al. OR
b) There must be an automatic disconnection of the mains, if the protective earth conductor breaks. See chapter 4 Power
cabling. OR
c) There must be a terminal for a second protective earth conductor in the same crosssectional area as the first protective
earth conductor.
Table 2: Protective earthing conductor cross-section
The values of the table are valid only if the protective earthing conductor is made of the same metal as the phase conductors.

CAUTION!
Make sure that the EMC level of the AC drive is correct for your mains. See chapter 6.5 Installation in an IT system.
An incorrect EMC level can cause damage to the drive.
CAUTION!
Prevent radio interference. The AC drive can cause radio interference in a domestic environment.
NOTE!
If you activate the autoreset function, the motor starts automatically after an automatic fault reset. See the Ap-
plication Manual.
NOTE!
If you use the AC drive as a part of a machine, the machine manufacturer must supply a mains disconnection de-
vice (refer to EN 60204-1).
