Chapter 2 Installation and wiring
2.1 Environment and installation requirements
3 The installation environment affects the life of the inverter and has a direct effect on
the normal function, failure to comply with the environmental specifications could lead
to a fault in the inverter.
4 For the VECTOR V 800 series inverter, use the vertical installation to ensure the best
possible air flow and heat dissipation effect.
5 Ensure that you can meet the inverter's installation environment:
6 (1) - 10 ° C to + 40 ° C ambient temperature
(2) Ambient humidity 0 ~ 95%, no condensation
(3) Avoid direct sunlight
(4) The surrounding environment does not contain corrosive gas and liquid
(5) Dust-free environments, flying fibres, cotton and metallic particles
(6) Without radioactive material and fuel
(7) Distance from an electromagnetic interference source (such as an electric welding
machine, a large powering machine)
(8) Install on a flat, vibration-free surface, if you cannot avoid vibrations, add anti-
vibration pad to reduce vibration
(9) Install the inverter in a well-ventilated place, easily accessible for maintenance and
for solid non-flammable material outside the heater (e.g. braking resistor, etc.)
7 (10) Installing the inverter requires plenty of space, especially in case more inverter
installations, be careful with the location of the frequency inverter and place the
cooling fans so that the ambient temperature is below 45 ° C.
8 (11) The rated output of the inverter applies to installations with an altitude of less than
1000 m. At an altitude above 1000 m the inverter performance decreases.
2.2 Connection of inverter V 800 to power grid
2.2.1 The descriptions of peripheral devices
(1) AC power supply
Use within the permissible power supply specifications of the inverter.
(2) Breaker
If the power supply voltage is low or the input terminal is short, the circuit breaker provides
the option of disconnecting the inverter from the power supply during inspection,
maintenance, or if the inverter does not work. Maximum disconnection times are according
to STN 33 2000-4-41. To protect the input of the inverter, fuses with gR and gG characteristics
