2. 240 Volts EP500Pro Backup System
You can build the 240V Split Phase System by pairing two EP500Pro units
together. The system also has double the available output power and capacity.
Besides Two EP500Pro units, you also need the following:
Please read the Reliance 310A Pro/Tran 2 manual before installation.
http://www.reliancecontrols.com/Documents/PT2%20Loadside%20Installation%20
and%20Operating%20Instructions.pdf
Before installing the Reliance Controls transfer switch system, please make a
emergency energy plan that includes which appliances you need during a power
outage. It is highly recommended to “balance the load” between the two phases of
transfer switch, that’s to say, do not connect high-wattage appliances centrally to a
single EP500Pro.

Connect the EP500Pro units to the main panel
Charge the 240V split phase system with EP500Pro 30A split phase AC charging
cable. Plug the cable to a NEMA L14-30 socket (240V )and the other two connectors
into the AC input ports of the EP500Pro units.
The AC input ports should be connected to L1/N/PE and L2/N/PE, respectively. The

3.8 Circuit breaker & protection box
If you have a residential solar array with a voltage of 12V-150V, you’re strongly
recommended to use a DC circuit breaker panel to enable or disable solar charging.
NOTE : If there are two solar panel arrays with a total open circuit voltage of 12-150V,
you also need two 2P 16A DC circuit breakers.
