III
Safety Guidelines
Only qualified person are allowed to install, operate and maintenance on CTH200 Series PLC.
Qualified persons are defined as persons who are authorized to commission, ground, tag circuits,
equipment, and systems in accordance with established safety practices and standards.
COTRUST has no responsibility for any consequence caused by using this product.
This manual contains notices that you should observe to ensure your personal safety, as well as
to protect the product and connected equipment. These notices are highlighted in the manual by
a warning triangle and are marked as follows according to the level of danger:
Warning
“Warning” sign indicates operation not as required may result in severe personal injuries or
even death.
Caution
“Caution” sign indicates operation not as required may result in personal injuries or device
damage
Notice
“Notice” sign indicates necessary supplements or explanations
Precautions for Use
There must be safety circuit to ensure the operation security of PLC system when the external
power off or PLC failed. Notices in design for use including:
Emergency brake circuit, safety circuit, positive/reverse operation interlock circuit and the
upper/lower limit interlock switch of position for preventing device damage must be implemented
in the PLC external circuit.
To ensure the device operation security, the external guard circuit and safety mechanism for the
output signal of major accident is a must.
The PLC can detect system exceptions which resulting all output turned off, to ensure the device
operation normal, external control circuits need to be added.
When the Relay or Resistor Unit in PLC was damaged, the ON/OFF for PLC Outputs cannot be
controlled.
The Power system should fitted with lightning protection device, to prevent the PLC interfaces,
like power/signal inputs and controller outputs from being damaged by lightning over-voltage.

IV
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.
