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 Weidos PLC from heat, high voltage, and electrical noise:
Always separate the devices that generate high voltage and high electrical noise from the Weidos PLC. When
configuring the layout of the Weidos 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. Also consider 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 high energy, rapidly switched DC wiring.
