Installation and Maintenance
Notes for installation:
- The installation position should be free from the following: dust or oil smoke,
conductive dust, corrosive or flammable gas, high temperature, condensation, and
rain.
- Besides, vibration and impact also affect the PLC normal operation and shorten its
lifespan; electric shock, fire or misact also damages the product. During drilling or
wiring, prevent the metal particles or wire segments from falling into the PLC casing,
which may cause fire, fault or misact.
- After the PLC installation, clean the ventilation duct to prevent blocking, which may
cause bad ventilation, or even fire, faults or misact.
- Do not online connect, plug or unplug cables, which is apt to cause electric shock or
damage the circuit. Installation and wire connection must be firm and reliable. Poor
connection could cause misact.
- Use shielded twisted pair for the I/O of high frequency signal and analog signal to
improve system IMS.
The installation environment should be free from dust, oil smoke, conductive particle,
corrosive or flammable gases, high temperature, condensation, and rain.
Besides, vibration and impact also affect the PLC normal operation and shorten its lifespan.
It is recommended to install the PLC, together with the matching switches and contactors,
in a dedicated electric cabinet and keep the cabinet ventilated. If the location has high
ambient temperature or heat generating equipment nearby, install forced convection
devices on top or sides of the cabinet to avoid over-temperature. During drilling or wiring,
prevent the metal particles or wire segments from falling into the PLC casing, which may
cause fire, fault or misact. After the PLC installation, clean the ventilation duct to prevent
blocking, which may cause bad ventilation, or even fire, faults or misact.
The only way to disconnect the equipment from the electrical network is by removing the
connectors that feed the equipment. Once installed in the electrical cabinet it is very
important to ensure the power connectors for proper operation.
Separate the ESP32 ETHERNET&WIFI&BLUETOOTH PLC from heat, high voltaje and eletrical
noise:
Always separate the devices that generate high voltage and high electrical noise from the
ESP32 ETHERNET&WIFI&BLUETOOTH PLC. When configuring the layout of the ESP32
ETHERNET&WIFI&BLUETOOTH PLC inside your panel, consider the heat-generating devices
and locate the electronic-type devices in the cooler areas of your cabinet. Reducing the
exposure to a high-temperature environment will extend the operating life of any
electronic device. Consider also the routing of the wiring for the devices in the electric
cabinet. Avoid placing low-voltage signal wires and communications cables in the same
tray with AC power wiring and highenergy, rapidly-switched DC wiring.
