Wall installation for size 1 devices
DANGER
The ground continuity between the base of the device and the bracket is ensured by the special component shown in the figure. Install this
component and verify the ground continuity between the bracket and the base of the device at the end of the installation.
Alternatively, it is possible to drill the aluminum base in the area where the four special fixing holes are.
The fixing screws must be equipped with O-rings to guarantee the protection rating.

WARNING
Read the safety chapter carefully before continuing.

7.1. Grounding

DANGER
Make sure that the device and the loads connected to it are properly grounded with the appropriate connection terminals before commissioning.
Ensure that the grounding system is compliant and refer to local regulations for grounding devices.
Each load must be fitted with its own earthing cable, the length of which must be as short as possible. Do not make interconnected grounding
connections.
Leakage currents may exceed 3.5 mA. It is recommended to use the reinforced ground connection if necessary.
Use the following minimum cross-sections for ground cables:
• cross-section equal to the mains power cable cross-section up 16 mm
• 16 mm2 (6 AWG) for mains power cable cross-section between 16 mm
• cross-section equal to half the cross-section of the power supply cable when the latter is greater than 35 mm

7.2. Protection devices

Fuses and switches.
The control device can protect the motor from overloads by digitally controlling the absorbed current against the set rated current.
It is therefore not necessary to install any overload protection device between the inverter and the motor.
Instead, it is necessary to install overcurrent and short-circuit protection devices, such as fuses and circuit breakers, upstream of the device. These trigger in the
event of failure of a component inside the device.
