CHINT NVF5 Series Instruction Manual page 3

1
Check the product nameplate with your order, do not install the product if there is any
inconsistency;
2 Do not install and operate the product if there is any damage in appearance or missing of any
parts, otherwise it may cause fire or injury;
3
To avoid dangerous accidents, the product must be installed and wired strictly according to the
instructions;
4 Do not install the product in inflammable, explosive, humid and condensing environment;
5
Do not install the product in places where there is direct sunshine or water leakage, otherwise the
equipment can be damaged;
6 Do not use your hands to touch main circuit terminals, control circuit terminals, electric
components and internal parts of the inverter directly;
7
The inverter must be installed by qualified person, otherwise electric shock can occur;
8
The inverter must be isolated from power supply through circuit breaker, otherwise there will be a
risk of fire;
9
The power and load connected to the inverter should comply with the requirements for inverter
input power and its matching motor;
10
When installing external live conductor, the exposed parts of the conductor should be insulated to
avoid electric shock;
11
Before installing, maintaning and servicing the inverter, turn off the power and wait for 10
minutes;
12 The inverter has gone through dielectric withstand voltage test before delivery. It is prohibited to
conduct such test on the inverter again, otherwise the equipment can be damaged;
13
If the length of motor cable exceeds 100 meters, user should use stranded wire and install an AC
output reactor to suppress high frequency oscillation, so as to prevent motor insulation damage
or too much leak current;
14
Non-professional is prohibited to conduct signal testing during operation, otherwise personal
injury or equipment damage may occur;
15
Do not start and stop the inverter frequently by connecting and disconnecting the power supply,
otherwise the equipment damage may occur;
16
In civil applications, the product may cause radio interference. In such cases, user may have to
take control measures such as installing reactor or filter;
17
The electrolytic capacitors in the main circuit and those on the printed board may explode and
the plastic components (such as panel) may generate poisonous gas during the disposal process,
therefore they should be disposed of as industrial waste;
18
It is prohibited to conduct maintenance, service and inspecton on live products, otherwise electric
shock may occur.
