6.7.2 Connection of a thermistor (PTC) to CUE
A PELV circuit provides protection against electric shock. Special
connection requirements apply to this type of circuit. The
requirements are described in EN 61800-5-1.
In order to maintain PELV, all connections made to the control
terminals must be PELV. For example, the thermistor must have
reinforced or double insulation.
6.7.2.1 Accessing the signal terminals
All signal terminals are behind the terminal cover on the front side
of CUE. Remove the terminal cover as shown in the figures below.
