To disconnect wire:
reverse the procedure
Instructions:
a)
Use appropriate copper cables, that are designed
for an operating temperature of 60°C
b)
Follow national installation codes and regulations.
c)
Ensure that all strands of a stranded wire are fully
inserted in the terminal connection.
d)
Up to two stranded wires with the same cross-
section are permitted in one connection point.

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.
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 given unit and does not
necessarily represent the life of a product.
