Instructions:
a) Use appropriate copper cables that are designed for an operating temperature of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C minimum.
b) Follow local and national installation codes and regulations!
c) Ensure that all strands of a stranded wire enter the terminal connection!
d) Up to two stranded wires with the same cross section are permitted in one connection point.
e) Ferrules are allowed but not required
f) In order to fulfill GL requirements, unused terminal spaces must be closed.
