12. Terminals and Wiring
Use appropriate copper cables that are designed for a minimum operating temperatures of 60°C (for ambient up to
45°C) and 75°C (for ambient up to 60°C). Follow national installation codes and regulations! Ensure that all strands of
a stranded wire enter the terminal connection! Do not use the power supply without PE (Ground) connection! Up to
two stranded wires with the same cross section are permitted in one connection point (except PE wire). Ferrules are
allowed, but not required.

The Lifetime expectancy shown in the table above indicates the operating hours (service life) and is determined by
the lifetime expectancy of the built-in electrolytic capacitors.
Lifetime expectancy is specied in operational hours and is calculated according to the capacitor’s manufacturer
specication. The prediction model allows a calc ulation of up to 15 years from date of shipment.
MTBF stands for Mean Time Between Failures, which is calculated according to statistical device failures, and indicates
reliability of a device. It is the statistical representation of the likelihood of failure of a specic unit and does not necessarily
represent the life of a product.
