E2648-C2H4

Rev 22.06.2021

NOTE! The outputs are not galvanically isolated from the external power supply and share
a common 0V. Allowed load resistance limits are stated in the Specifications table. To
power the instrument from an external power source, connect terminals 0V and +U to the
source. If the integrated mains power supply module is used, connect terminals L and N to
the mains.

NOTE! Actuator short-circuits should be avoided, to protect the instrument relays using
external fuses or safety switches.
