WARNING
Always read this manual thoroughly before using DVP
PLC.
AC input power
must be disconnected before any
maintenance.
This is an OPEN-TYPE PLC. The PLC must be placed
in an enclosure to meet the safety approval of IEC
61131-2 and UL 508.
The PLC should be kept in an enclosure away from high
temperatures, humidity, vibration, corrosive gas, liquid,
airborne dust and metallic debrise.
Do not connect the AC main circuit power supply to any
of the input/output terminals, as it will damage the PLC.
Ensure all the wiring prior to power up.
Disconnect all power. Wait one minute for capacitors to
discharge before touching internal circuit.
Some models are equipped with DC power supply
output, do not exceed its rated output power.
Make sure the PLC is properly grounded , to avoid
any electromagnetic noise.
