Power source
PV037/PV057 is equipped with DC24V input. If the supply power is other than
DC24V, less or excess, it will severely damage the HMI. Therefore, check the
switching power supply supporting the DC power regularly.
To avoid electronic shock, be sure the Power Cable is unplugged from the
power outlet when connecting the cable to the HMI.
Grounding
From the FG terminal at the rear side of HMI, please make sure the grounding
is made exclusively.
When the FG terminal is connect, be sure the wire is grounded. Without
grounding, the operation of HMI may be severely affected by excess external
noise levels and vibrations.
Use a cable at 2 m(AWG 14) to ground the equipment. Ground resistance
must be less than 100 (class3).Note that the ground cable must not be
connected to the same ground point as the power circuit.
Installation
Mount the HMI from the front of a suitable preserved hole.
Attached the brackets behind.
Fasten the screw of the brackets with proper force. Tightening too much may
cause damage to the structure of the unit.
Input and Output signal lines must be separated from the power cables for
operational circuits. Use shielded cables or it may cause unpredictable
problems.
Do not allow cut wires, filling, or shavings to fall inside a unit or block when
drilling holes or connecting cables/lines.
Environment
Do not install in areas subject to excessive dust, oily mist, conductive dust,
corrosive gas, or flammable gas.
Do not mount in areas subject to shock or vibration.
Do not mount in areas subject to high temperature, moisture, or rain.
Indicated loss of life, severe personal injury, or substantial property
damage will result if proper precautions are not taken.
