1. Insert the wire

2. Close the lever

To disconnect wire:

reverse the procedure

 

 

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

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 parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time  
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.
