1.1 Safety instructions
Thank you for choosing Shihlin inverters of SC3 series. This instruction introduces how to correctly use this inverter.
Before using this inverter, always carefully read this User Manual and moreover, please understand the safety
instructions.
Installation, operation, maintenance and inspection must be performed by qualified personnel.
In this instruction, the safety instruction levels are classified into "Warning" and "Caution".
Warning: Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Caution: Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause
only material damage.
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the
front cover or the wiring cover removed. Otherwise you may access the exposed high voltage terminals or the
charging part of the circuitry and get an electric shock.
It is crucial to turn off the motor drive power before any wiring installation or inspection is made. Before the inverter
CHARGE light is OFF, which indicates that there is still high voltage in it, please do not touch the internal circuit
and components.
The inverter must be connected to the ground properly.
Do not operate or touch the radiator or handle the cables with wet hands. Otherwise you may get an electric
shock.
Do not change the cooling fan while power is ON. It is dangerous to change the cooling fan while power is ON.
The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
Do not conducts a pressure test on the components inside the inverter, for semiconductor of the inverter is easily
to be broke down and damaged by high voltage.
While power is ON or for some time after power-OFF, do not touch the inverter as it will be extremely hot.
Touching these devices may cause a burn.
The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise burst, damage, etc. may occur.
Inverter must be installed on a nonflammable wall without holes (so that nobody touches the inverter heatsink on
the rear side, etc.). Mounting it to or near flammable material may cause a fire.
If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current may
cause a fire.
