(*) ADL500 can only operate on IT networks devoid of any faults (between active parts and PE) or in the presence of
temporary faults.
Therefore an insulation monitor MUST be used to detect and enable prompt removal of any fault condition.
Insulation monitor
Since the ADL500 drive is normally used in a ground-insulated system (IT), in accordance with IEC 61557-8, use of
insulation resistance monitoring is required.
The monitoring system must be able to detect insulation loss, both on the AC and DC power supply sides and on the
motor side.
A ground fault must be promptly detected and removed as quickly as possible to avoid damage to either the inverter
or the entire system as a unit (in the event of insulation loss, the drive must be immediately disabled and disconnected
from power sources).
The insulation monitor must be selected on a case-by-case basis according to the power supply, connection system
and type of drive.
Recommended insulation monitors e.g.: see the BENDER © ISOMETER® line.
The insulation monitor must be plugged into the main power supply (if ADL500 is AC powered) or the DC side (if
ADL300 is DC-powered).
The insulation monitor alarm threshold should be set to the highest possible resistance value.
