Instructions:
a) 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
90°C for ambient up to 70°C minimum.
b) Follow national installation codes and installation regulations!
c) Ensure that all strands of a stranded wire enter the terminal
connection!
d) Do not use the unit without PE connection.
e) Ferrules are allowed.
1. Insert the wire 2. Snap the lever
To disconnect wire: same procedure
vice versa
Daisy chaining:
Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current
through one terminal pin does not exceed 27A. If the current is higher, use a separate distribution terminal block as
shown in Fig. 12-2.
