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 specified in operational hours and is calculated according to the capacitor’s manufacturer

specification. The prediction model allows a calculation of up to 15 years from date of shipment.

MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates

reliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily

represent the life of a product.
