Hi- We have a problem with a 1336S drive from AB. We get a failure
every time the ambiant temperature reaches 35C. It's installed in a
panel (80x48x14). The heatsink are external and clean. We have
installed an air conditionning unit with 4000BTU capacity. The drive
supply's 250 Amps at 575 Volts. It's controled via HMI and PID loop.
Can you give us a hint on what to do or what the causes could be.
