1SYSTEM OVERVIEW
WARNING
Emergency Power Off (EPO) instantly disconnects the aGate X main relays to these
electrical connections: Utility grid, solar PV, external generator and the aPower X battery
system. The auxiliary power connection from the aPower X to the aGate controller
remains ON.
Do not use the EPO for maintenance operations or in any situation other than an
emergency.
When an emergent situation occurs, such as fire or a smoking battery, the user may manually press
the EPO (Emergency Power Off) button to power off the system, where it is safe to do so. The external
EPO is an optional component. If the user wishes to have the external EPO function, he/she needs to
consult with the installer to have the EPO installed.
Please note the following when choosing the external EPO:
⚫Must be labeled as "Emergency Stop Button", "Emergency Stop Device", "Emergency Stop
Unit".
⚫Must have an ON/OFF switch that maintains its position after being manually set to
either status.
⚫Must have a clear indication of the ON/OFF positions.
⚫Must be outdoor rated (NEMA 3R or higher).
⚫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
shown in the figure).

2STATE DESCRIPTION
The EPO ON/OFF states are as follows:
ON: When the NC (normal close) of EPO is connected, EPO is in the ON state. And the system is
working normally.
OFF: When the EPO button is pressed, the EPO is in the OFF state. That means the EPO function has
been activated to protect the system. At this time, aPower X will be shut off and all relays inside aGate
X (including the Supply Relay, the Generator Relay, the Smart Circuits Relay, and the Solar Relay) will
be disconnected.

DANGER
Before the installation starts, please disconnect all breakers in the aGate X (including the
Solar, aPower X, Smart Circuits, Grid, and Generator breakers), the system control switch,
and all ON/OFF switches of external devices, and then lock the breakers and switches by
a LOTO (Lockout Tagout), so as to completely power off the whole FHP system. Wait at
least five (5) minutes before proceeding with further operations.

EPO Installation Steps:
Step 1. Open the aGate X door.
Step 2. Disconnect all breakers in aGate X (including the solar, the aPower X, the Smart Circuits,
the grid and generator breakers), the system control switch, and all switches connecting
external devices to the aGate X.
Step 3. Wait at least five (5) minutes, and then loosen and remove the six M5×12 screws using
a Phillips head screwdriver, and remove the inner panel from aGate X.
Step 4. Use a multimeter to measure and check that the AC voltages at both input and output
terminals of the aGate X (as shown below) are zero (0), to ensure that all electrical
equipment have been disconnected from the aGate X.
Step 5. Remove the short connector on the EPO of the EMS module.
