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.

Lifetime expectancy min. 41 000h 40°C, stand-by mode
min. 116 000h 25°C, stand-by mode
MTBF SN 29500, IEC 61709 2 327 000h 40°C, stand-by mode
4 219 000h 25°C, stand-by mode
MTBF MIL HDBK 217F 398 000h 40°C, stand-by mode, ground benign GB40
624 000h 25°C, stand-by mode, ground benign GB25
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 specifications from the manufacturer of the capacitor.
MTBF means Mean Time Between Failures, which is calculated according to statistics of device failures, and
indicates reliability of a device. It is the statistical representation of the likelihood of failure of a given device, and does
not necessarily represent a life of a product.
