I cant figure out how to get the wires out off the terminal block of the input voltage transformer. There are no visible screws . I need to change to voltage jumper wires for my higher voltage which is 240v delta 3 phase. my voltage is 245 with 1 meter and 251 using another test meter. so should I use the 250v or the 260 v settings. the manuals say to error to to high side for safety of the drives . And how do you get the front Y axis way cover off . I removed the 2 screws into the table but it is still mounted solid somewhere. Thanks for now
