The E3PS12-75 should be installed and operated as specified herein.
Failure to do so may impair or defeat any protections provided by the
equipment. Please read and follow all instructions before installing or
operating this device.
General Safety
The power supply should be mounted behind covers or machine skins
that can only be opened with a tool. The covers or machine skins
should be marked as having hazardous voltages within. Alternatively,
the supply can be mounted behind doors that have a safety interlock
that removes power to the supply when opened.
The power supply should not be mounted in an area where the
ambient temperature exceeds 40°C.
