Installation Guidelines

Mount the EL3051 onto a 35 mm DIN rail (EN 60715) using the integrated locking mechanism.
Use the double slot and key connection for secure side-by-side assembly with other EtherCAT terminals.
Connect wiring using spring-actuated terminals, suitable for both solid and flexible conductors (stripping length 8–9 mm).
To ensure measurement accuracy, follow EMC installation standards (EN 61000-6-2/EN 61000-6-4) to minimize electrical noise on the current loop.
Maintain the ambient operating temperature between -25 and +60 degC.
