Why You Need the Manual (Even if You Think You Don't)

While installing an RCD seems straightforward, the Multi 9 IC2000 P has specific nuances:

Terminal Torque: The manual specifies exact tightening torque (usually around 2 Nm for 25A-63A). Too loose, and you get arcing; too tight, you strip the aluminum busbar.
Sensitivity (IΔn): The IC2000 P comes in variants like 30mA (personnel protection) or 300mA (fire protection). The manual clarifies the tripping curves and disconnection times.
Voltage Rating: It is rated for 240/415V AC. Do not use it on DC circuits.
