I'm trying to install a new style main switch into an older EK. The new switch has a fifth connection that the old switch does not. The switch doesn't seem to get power without the fifth terminal connected.
Anyone know where this connects to? Having a hard time seeing it in the wiring diagram.
Also, what is E1 and L1 in the wiring diagram connected to the 3 block om the terminal block? I suspect this has something to do with the fith connection on the switch.
Thanks a lot in advance for the help!
