TECO Electric & Machinery Co., Ltd
Safety Precaution
.ⅠPrecaution for Installation:
Never install the product in the environment beyond the one brochure and user
manual specified, such as high temperature, humidity, dust, erosive gas,
vibration, impact condition resulting in the risk of inductive electricity, fire and
error operation.
Please exactly comply with the installation instruction in the user manual, or the
undesired situation as falling down, accident or error operation would happen to
the SG2.
Pay close attention to the cable and conductor incidentally fall into the module
to prevent fire, trouble and wrong action.
.ⅡPrecaution for Wiring:
Connect Class 3 grounding in accordance with the Electricity Engineering
Regulations. NO grounding or improper grounding might lead to troubles such
as electric shock and error operation.
Apply the rated power supply and specified cables. Wrong power supply would
render fire.
The wiring shall be carried out by the certified electrician pursuant to the
provisions set forth in the Electricity Engineering Regulations.
Improper wiring would lead to fire, trouble, and induction electricity.
.ⅢPrecaution for Operation:
When the power is on, never contact the terminal to avert electrical induction.
It is strongly recommended to add the safety protection such as the emergence
stop and external interlock circuit to prevent the SG2 from trouble and
mechanical damage.
Run the SG2 after safety confirmation. Error operation will result in mechanical
damage.
Please pay attention to the power on procedure. Wrong process flow would lead
to mechanical damage or other hazards.

Installation drawing
2-3 Wiring
◎ The I/O signal cables shall not be routed parallel to the power cable, high current cable or
in the same high current cable trays to avoid the signal interference.
2-4 Static Electricity
◎ In the extremely arid area, the humans’body is susceptible to generate of static electricity.
Never touch the SG2 with hands to avert static damage to the SG2.
2-5 Cleanness

2-2
with water or volatile solvent to prevent structure deformation and discoloration.
2-6 Storage
◎ The time memory of SG2 RTC applies super capacity which is susceptible to high
temperature and humidity. The SG2 shall be kept away from the said place.
2-7 Over-current Protection
◎ The SG2 is not incorporated a protective fuse at the output terminal. To avoid the short
circuit on the load side, it is recommended to cable a fuse between each output terminals
and loads.
