Installation

DDC30-20-65 surge protectors are connected in parallel on the DC network and must be equipped with external fuses for short-circuit current protection

The total length of parallel connection wires to DC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
Wiring is made by screw connections. On some models, a distribution bus can be used.
The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
Local earthing resistance must be in compliance with the electrical rules.
