1. Insert the wire 2. Close the lever
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 enter the
terminal connection!
d) Up to two stranded wires with the same cross
section are permitted in one connection point
16. RELIABILITY
Lifetime expectancy min. 137 400h At 10A output current, 40°C
min. > 15 years At 5A output current, 40°C
min. > 15 years At 10A output current, 25°C
MTBF SN 29500, IEC 61709 886 000h At 10A output current, 40°C
1 482 000h At 10A output current, 25°C
MTBF MIL HDBK 217F 397 900 At 10A output current , 40°C, ground benign GB40
545 000 At 10A output current , 25°C, 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 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.
All values except battery.
