Overview of energy applications

The wiring diagram S-EM1 on the inside of the upper section of the housing summarises all con-
nection variants of the device version for heat meters. The diagram shows the standard assembly
with the modules (left to right). The display module is not shown.
• CPU module
• Input module
• Supply or Connect Module (power supply)
Up to four additional input, output or communications modules can be fitted between the supply
and input modules.
