Since the OP didn't describe the environment.. it may or may not be.
For aircraft work (yes, some is 60Hz) it would be a really good idea
to check. If it's sitting on a subpanel with the control cabinet
bolted to the floor rather than to an OBI punch press, not a big deal.

It's usually in old (60's & 70's) V-belt driven letterpress type printing
presses (think "clamshell" press). No vibration at the controls.

Thanks,
