Before installing, operating, and maintaining the micro- programmable control, be sure to
familiarize yourself with this user manual and other related manuals to ensure proper use.
Please use it after you are familiar with the operation method, safety information and all
precautions.
In this manual, safety precautions are classified into two categories: "warning" and "caution".
Before installation, operation, maintenance and overhaul of the product, please
be sure to read the user manual and other related manuals to ensure correct use.
Failure to follow the instructions in the manual may result in improper installation
, use and storage of the equipment, which may result in personal injury or even death, and
property damage.
Part 1 Design Precautions
To ensure safety system operation, please configure emergency braking circuit, positive
inversion circuit or other similar protection circuit for PLC, which protection circuit can prevent
the damage to PLC or other devices.
●External power supply would break down unexpectedly.
●All outputs are turned off, as an error be detected by PLC CPU during self- diagnosis, such
as a watch dog timer error. When error that cannot be detected, internal protection circuit may
be disabled.
●The output state of relay or transistor in the PLC can't be controlled, when relay or transistor
is damaged.
Part 2 Installation Precautions
●Always make sure to install PLC on vertical plane, not on broadside.
●50mm safe distance must be kept with other devices, and far away
from the high-voltage power line, high-voltage device and the power
equipment.
●Never use the product on condition with dust, oily smoke, conductive dusts, corrosive gas,
flammable gas, vibration or impacts, or expose to high temperature, fire or rain.
●Do not leave anything in the vent. when installation or wiring is completed.
●Always make sure to remove the dust proof sheet from the PLC's vent when installation or
wiring is completed.
