Danger
Some parts of the power system are operated with high voltage. Direct contact or indirect contact
with these parts through wet objects can be fatal.
Caution
Static electricity generated by the human body can damage static-sensitive components on the
board, such as large-scale integrated circuits (ICs). Before touching the device, holding the card,
circuit board, IC chip, etc., in order to prevent the human body from damaging the sensitive
components, you must wear an anti-static wrist and ground the other end of the ESD-preventive
wrist.
Danger
It is strictly forbidden to short-circuit the positive and negative poles of the power distribution
system DC power supply or short-circuit the non-grounding pole to the ground. The power supply
equipment is a constant voltage DC power supply equipment, and short circuit will cause
equipment burnout and personal safety hazard.
Danger
It is strictly forbidden to carry out high voltage and alternating current in thunderstorms.
Danger
Construction operations on high voltage lines may result in fire or electric shock. The area where
the AC cable is routed and routed must comply with local regulations and specifications. Only
those with qualifications for high voltage and AC operation can perform high pressure operation.
Safety Precautions
Please read the operating instructions and precautions carefully before starting the operation to reduce the accident. The
“Caution, Warning, and Danger” items in the product and product manuals do not represent all safety precautions that
should be followed, and are only supplementary to various operational safety precautions.
In the operation of our products and equipment, we must abide by the safety regulations of relevant industries and
strictly abide by the relevant equipment precautions and special safety instructions provided by Power Elektronik SAN.
A.Ş.
Electrical Safety
High Voltage
The installation of AC power equipment must comply with the safety regulations of relevant industries. Personnel
performing AC equipment installation must have high-voltage, AC, and other operational qualifications.
It is strictly forbidden to wear conductive objects such as watches, bracelets, rings, etc. on the wrist during operation.
When you find that the cabinet is watered or wet, turn off the power immediately. When operating in humid environment,
moisture should be strictly prevented from entering the equipment.
On the switches and buttons that are not allowed to be operated during installation, the prohibition operation sign must be
hung.
Tools
Warning
Special tools must be used for various operations of high voltage and alternating current
Thunderstorm
In thunderstorms, strong electromagnetic fields are generated in the atmosphere. Therefore, in order to avoid lightning
damage to the equipment, it is necessary to do a good grounding of the equipment in time.

The polarity of the cables and interface terminals must be strictly checked during DC live working.
DC power distribution operation space is compact, please pay attention to choose operating space before any operation.
Operation must use insulation tools.
When charging operation, you must pay attention to the tension of the hands, wrists and arms to prevent the tool or the
human body from moving too much and causing accidents.
Others

Warning
Wear protective gloves when handling equipment by hand to prevent cuts from sharp objects.
Power cable
Caution
Make sure the cable label is correct before connecting the cable.
Signal line
Caution
The signal cable should be bundled separately from the power cable. The distance between the
straps is at least 150mm.
