How to Configure Circuits For 208v in an Echo Relay Panel

Symptoms/Issue

I have a 120v/208v ERP Mains Feed that requires 2 relays to be 208v. How can I make this happen? 

Solution

This will require the addition of a double pole, double space 20A relay and a double pole, double space 120v breaker. See page 7 of the ERP Mains Feed Installation Manual for relay and breaker varieties. 

From the ERP's UI, the circuit must be configured as a 2-Pole relay from Switching Setup.
