Reinforced insulation (IEC/EN 61800-5-1:2007)
Functional insulation (IEC/EN 61800-5-1:2007)
The terminals on the control board fulfill the Protective Extra Low Voltage
(PELV) requirements (EN 50178): There is reinforced insulation between the
user terminals which only accept ELV voltages and terminals that accept
higher voltages (relay outputs).
Note: There is functional insulation also between the individual relay outputs.
Note: There is reinforced insulation on the power unit.
