Grounding (Earthing)

The pin terminals must be completely inserted into the connector supplied with the
unity so that no metallic parts are exposed, according to the figure below.
A 1.5 mm² ground lead must be connected to the terminal marked with the protective
ground symbol for safety.
For AC power connection, the phase conductor must be applied to terminal (+/L),
neutral conductor to terminal (-/N) in the supply terminals identified as illustrated
below.
For DC power connection, the positive line should be applied to terminal (+/L), negative
to terminal (-/N) in the supply terminals identified as illustrated below.
For compliance with IEC 61010, install a suitable external switch or circuit breaker in
each current-carrying conductor of RT412 power supply; this device must interrupt both
the hot (+/L) and neutral (-/N) power leads. An external 10 A, category C, bipolar circuit-
breaker is recommended. The circuit breaker should have an interruption capacity of at
least 25 kA and comply with IEC 60947-2. The switch or circuit-breaker must be suitably
located and easily reachable, also it must not interrupt the protective ground
conductor.
To ensure proper operation of the equipment under extreme electromagnetic
conditions, connect the equipment protective ground terminal to the panel using a
copper strap of at least 10 mm width as M6 ring lug.
