Precautions for Installation
Do not install PLC at places with: dust, smut, conductive dust, corrosive gas, combustible gas,
vibration and shock. Do not expose the PLC in environment like high temperature, moisture
condensation and raining. Thunder strike, fire or disoperation can also cause product damage.
Prevent the metal filing and cable outlet falling into the PLC ventilation hole when wiring and
tightening the screws, for it may cause fire, failure and misoperation.
After installing PLC, there must be no sundries in case of fire, fault and misoperation caused by
bad heat dissipation.
Hot plugging is not allowed, shield cable must be used to increase immunity of inference.
In situations with serious interference, shielded twisted pair is recommended to improve the
anti-interference ability of the system.
Precautions for Wiring
Before Installation and wiring, all external powers must be cut-off, otherwise there maybe electric
shock and device damage.
Cover the terminal plate before powering on, follow the instructions in this manual to connect
power.
PLC in/out signals wires cannot be parallel with other high voltage or interference lines, they
should be layout in separate slots.
Separate the PG terminal on CPU with that of high voltage.
Operation and Maintenance
Do not touch the terminals with power on, in case of electric shock and device damage.
Clean and tighten screws, connect and dismantle cables or expansion modules after power off,
or it may cause electric shock and device damage
Do not dismantle the controller in case of damaging the internal parts.
Please reading this manual before modifying, testing, startup and stop programming.
Product Discard
The combustion of electrolytic capacitor on PCB can cause explosion, the main material on PLC
is plastic which would generate toxic gas when burnt.
Please follow the local environment regulations to dispose the abandoned products.
