Because of the ever present danger of electrical shock, be sure to unplug the power cable from the FP unit before
plugging the cable’s other end into the wall.
Do not use power in excess of the unit’s specified voltage range since it may cause a fire or electric shock.
Because the FP unit contains high voltage parts, an electric shock can occur when disassembling the unit. Therefore,
be sure to always unplug the unit before disassembling it.
Do not modify the FP unit in any way, since it may cause a fire or electric shock.
Do not use touch panel keys to perform life-threatening or vitally important safety functions. Use separate mechani-
cal switches for such keys.
Do not use the FP unit as a warning device for critical alarms that can cause serious operator injury, machine damage
or production stoppage. Critical alarm indicators and their control/activator units must be designed using stand-alone
hardware and/or mechanical interlocks.
