Manual for Zenith 500A

[plantainsingreen09]

I'm working on an older Zenith 500A transfer switch (208V, 3-phase) at a small clinic we're upgrading. It's running the MX150 control board, and everything's been good so far.

Now we're adding remote monitoring, and I need the O&M manual and wiring diagrams to figure out the signal connections. I've searched around but haven't found the right docs yet, maybe I'm missing something?

Anyone worked with this setup or know where I can find the manuals? Big thanks!

Try to contact Zenith/GE directly, they may email you the O&M and wiring diagrams if you provide the model and serial number
