Chapter I Safety Information and Precautions
Chapter I Safety Information and Precautions
There're two types of safety precautions provided in this Manual:
DANGER: It indicates that failure to operate following the requirements will
result in severe personal injury or even death;
WARNING: It indicates that failure to operate following the requirements will
result in moderate or minor personal injury or damage to equipment;
Read and follow the safety information and instructions provided in this Chapter
carefully so that you understand how to install, commission, operate and maintain
the system. We accept no liability or responsibility for any injury or loss caused by
improper operation of the equipment described in the Manual.
1.1
Safety Concern
1.1.1
Prior to installation:
◆
Never install the equipment if the control system shows signs of water entry and parts
missing during unpacking inspection, or if parts are missing!
◆
Handle the product with care, otherwise there is a risk of damage to the equipment!
◆
Never touch the components of the control system with your hands, otherwise there
may be a danger of electrostatic damage!
1.1.2
During installation:
◆
Install the equipment only on fire-retardant or incombustible objects such as a metal
object. Otherwise, a fire alarm may occur!
◆
Do not loosen the fixed screws on components. It is especially important not to remove
screws that have a red mark!
◆
Install the inverters in a location with less vibration and where it is not in direct sunlight.
◆
If the same cabinet includes more than one inverters, make proper installation
arrangements to cool the equipment.
1.1.3
During wiring:
◆
A circuit breaker must be provided to isolate the inverter from the power supply,
otherwise a fire alarm may occur!
◆
Make sure that the power supply is in zero-energy state before wiring, otherwise an
electric shock may occur!
◆
Make proper grounding to the inverter according to the relevant standard, otherwise an
electric shock may occur!
◆
Never connect power cables to the output terminals (U, V, W) of the inverter.
◆
Make sure that the circuits connected satisfy the EMC requirements and the safety
standards of the area.
◆
Never connect the braking resistor between the DC bus terminals (+) and (–).
Otherwise, a fire alarm may occur!
1.1.4
Before power on:
◆
Make sure the voltage class of the power supply is consistent with the rated voltage
class of the inverter; make sure the input terminals (R, S, T) and the output terminals (U,
V, W) are connected correctly; make sure there are no short-circuits in the peripheral
circuitry that is connected with the drive; make sure the cables and wires are secured
