Only just walked in , what a bloody day i have been run ragged all day, then i get a call at 2pm from one of my customer's saying they have a problem with their large grinder.
Apparently they had sent the work head away to be repaired! new bearings and a general overhauland. To save ringing me to disconnect the Motor, the Machine operator took it upon himself to disconnect and reconnect the motor, everthing was going great until he switched it on at the panel.
I get there start checking the circuit, take off the terminal cover to find he had wired 3 phases across the start point[/B totally knackering the 2.2kw 3 phase inverter. Plantpot!
so new inverter set all parameters job done, why do people who don't know what they are doing attempt these things.
Anyway just got home, so looks like being a takeaway.
