Introduction

The attachment of both units is achieved by sliding them over the DIN rail
with the clip assembly pulled out and then releasing it when correctly posi-
tioned.
The 24V supply source should possess the following characteristics:
Because of power limitations, it should be noted that although up to 11
SMART-Modules are possible in a complete configuration, attention should
be paid to the following tables that show the individual component power
requirements. The maximum of 6750mW should not be exceeded as damage
to the on-board DC-DC converter may result due to overheating or entering a
reset status due to the thermal cutoff protection switching mechanism.
