Instructions for wiring:
a)
Use appropriate copper cables that are designed for an operating temperature of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C minimum.
b)
Follow national installation codes and installation regulations!
c)
Ensure that all strands of a stranded wire enter the terminal connection!
d)
Up to two stranded wires with the same cross section are permitted in one connection point (except PE wire).
e)
Do not use the unit without PE connection.

The
Lifetime expectancy
shown in the table 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. Lifetime expectancy is calculated according to the capacitor’s
manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment.

ailure, which is calculated according to statistical device failures, and indicates
reliability of a device. It is the statistical representation of the likelihood of the unit to fail and does not necessarily
represent the life of a product.
