To connect the chassis to ground, use a ring-type terminal (ring cable lug) which is suitable
for a M4 screw and connect it to the chassis ground terminal on top of the unit.
Connecting Terminals
1.
The external circuitry of all terminals must meet the safety requirements stipulated by
IEC/EN/UL 60950-1: SELV.
2.
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.
3.
Follow national installation codes and installation regulations!
4.
Ensure that all strands of a stranded wire enter the terminal connection!
5.
Screws of unused terminal compartments should be securely tightened.
