Generally, the two terminal switches have NC contact only, in the normal condition it keeps the contact closed and allows the current to flow through it but when we operate the switch, it disconnects its NC contact and stops the current flow through it.. ⚫ The maximum low voltage wire running between the EPO switch and the aGate X should not exceed 150 feet (45 m). ⚫ The EPO shall have a rated voltage of 5V or higher. NOTE If the external EPO is not connected to the Franklin Home Power (FHP) system, please keep the factory default settings (the EPO module is short connected on the EMS module as
It illustrates how the EPO switch is connected to the power supply, control panel, and other equipment in the circuit. By referring to the diagram, electricians and maintenance personnel can easily identify the correct wiring connections and ensure that the EPO system is properly installed and functioning as intended.. EPO wiring diagrams.. Emergency Power-Off System The Emergency Power-Off (EPO) System consists of one or more wall-mounted, push-button EPO boxes. Each EPO box provides a single point of equipment shutdown for up to eight APC
