a) The external circuitry of all terminals (including signalling contacts) must meet the safety requirements stipulated by
IEC/EN/UL 60950-1: SELV.
b) Use appropriate copper cables that are designed for minimum operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C minimum.
75°C for ambient up to 60°C minimum.
c) Follow national installation codes and installation regulations!
d) Ensure that all strands of a stranded wire enter the terminal connection!
e) Up to two stranded wires with the same cross section are permitted in one connection point.
f) Screws of unused terminal compartments should be securely tightened.
g) Ferrules are allowed, but not required.
h) Do not connect or disconnect the wires from the terminals below -25°C (-13°F).
