THERMISTOR INSULATION
Risk of personal injury or equipment damage.
To meet the PELV insulation requirements, use only thermistors with reinforced or double insulation.

EXCESSIVE HEAT AND PROPERTY DAMAGE
Overcurrent can generate excessive heat within the drive. Failure to provide overcurrent protection can result in risk of fire and
property damage.
Additional protective devices such as short-circuit protection or motor thermal protection between drive and motor is

required for applications with multiple motors.
Input fusing is required to provide short-circuit and overcurrent protection. If fuses are not factory-supplied, the installer must

provide them. Refer to the product-specific documentation for fuse specifications.
PROPERTY DAMAGE
Protection against motor overload is not active by default. Failure to set the ETR function means that motor overload protection is
not provided and property damage can occur if the motor overheats.
To provide class 20 motor overload protection, enable the ETR function. See the programming guide for more information.
