Low voltage input
See Figure 3.
Incoming low-voltage inputs, usually telephone lines must, if not an earth cable, be
protected by lightning protection RR-192500. This is a surge and transient protection.
Assembly must be such that there is no obvious fire hazard.
The earth connection must be to the earth electrode system or common earth
terminal.
The connecting leads must be at least 6 mm copper and insulated.
