Where can I find the user manual for the

I am an engineer at a power plant responsible for testing generators and batteries. We were given a new Canoga Perkins 9145E electronic controller for load testing, but I have not worked with this model before. I need to read the manual in order to correctly connect the power supply and configure the modes without burning out the equipment, but the manual was lost during delivery. Does anyone have a copy of the manual or know where I can find one online?
