Important Notices
Caution
To ensure the device in reliable use and
personal safety, please abide by the following
items when in installation, use and maintenance:
Notice in installation
◆ Please DO NOT use the product in following
places: the places with dust, oily smoke,
electrical conductive dust, corrosive gas,
inflammable gas; the places with high
temperature, due, rain and wind exposures; the
places endangered by shock and vibration.
Electric shock, fire and incorrect operation could
also cause damage and deterioration to the
product.
◆ When conducting screw drilling and wiring
process, DO NOT let metal irons and wire lead
drop into the controller and air vent, which could
possibly cause fire, failure and accidental
operation.
◆ After finishing the installation, it is necessary
to ensure there is no foreign matter including the
packing material like contact paper on the
ventilation surface, otherwise, it could cause
poor heat dissipation while running, as well as
fire, failure and accidental operation.
◆ Avoid conducting wiring and plugging in/out
cable socket with electricity, otherwise, electric
shock, circuit damage could easily happen.
◆ Installation and wiring should be firm and
reliable. Poor contact could cause malfunction.
◆ With regard to the application situations with
strong interference, shielded cable should be
used for the input and output of HF signal, to
improve the anti-interference performance of the
system.
Note in Wiring
◆ Installation and wiring shouldn't be conducted
until external electric power is cut off, otherwise,
electric shock or device damage could happen.
◆ The product is grounded by the earth lead of
the power cable. To avoid electric shock, the
earth lead is necessary to be connected with the
ground. Before making connection with the
output end or input end of the product, please
ensure it is correctly grounding.
◆ Upon finish wiring, remove the sundries.
Please cover up the terminal plate for avoiding
electric shock.
Note for Operation and Maintenance
◆ Please DO NOT touch the terminal when with
electricity, otherwise, electric shock could
happen.
◆ Don't clean up and screw the terminal tight
before power is off. Such operation could cause
electric shock when with electricity.
◆ Please turn off the power before connecting or
disconnecting the communication signal cable,
peripheral modules or control units, otherwise,
device could be damaged and accidental
operation could happen.
◆ Please DO NOT disassemble the device, so
as to avoid internal electric components damage.
◆ It is necessary to read through the Manual and
fully ensure the safety, before altering the
program, trial running, starting and stopping
operation.
