The terminals on the RMIO board as well as on the optional modules attachable to the board fulfill the
Protective Extra Low Voltage (PELV) requirements stated in EN 50178 provided that the external
circuits connected to the terminals also fulfill the requirements and the installation site is below
2000 m (6562 ft). Above 2000 m (6562 ft), see page 61
