4.2.1 Installation environment

Installation environment is essential for the VFD to operate at its best in the long run. The installation environment of the VFD should meet the following requirements.

Environment	Condition
Installation site	Indoors
Ambient temperature	-10–+50°C; When the ambient temperature exceeds 40°C, derate 1% for every additional 1°C; It is not recommended to use the VFD when the ambient temperature is above 50°C; In order to improve reliability, do not use the VFD in cases where the temperature changes rapidly; When the VFD is used in a closed space eg control cabinet, use cooling fan or air conditioner to prevent internal temperature from exceeding the temperature required; When the temperature is too low, if restart a VFD which has been idled for a long time, it is required to install external heating device before use to eliminate the freeze inside the VFD, failing to do so may cause damage to the VFD.
Humidity	The relative humidity (RH) of the air is less than 90%; The max RH cannot exceed 60% in the environment where there are corrosive gases.
Storage temperature	-30–+60°C
Running environment	The installation site should meet the following requirements. Away from electromagnetic radiation sources; Away from oil mist, corrosive gases and combustible gases; Ensure foreign object like metal powder will not fall into the VFD (do not install the VFD onto combustible object like wood); Away from radioactive substance and combustible objects; Away from corrosive liquid; Low salt content; No direct sunlight
Altitude	Below 1000m; When the altitude exceeds 1000m, derate 1% for every additional 100m. When the installation site altitude exceeds 3000m, consult the local INVT dealer or office.
Vibration	The max. amplitude of vibration should not exceed 5.8m/s2 (0.6g)
Installation direction	Install the VFD vertically to ensure good heat dissipation effect

Note: GD350 IP54 series VFDs must be installed in ventilated environments free of corrosive gases and conductive dust.

4.2.2 Installation direction

The VFD can be installed on the wall or in a cabinet.

The VFD must be installed vertically. Check the installation position according to following requirements. See Appendix C "Dimension drawings" for detailed outline dimensions.

Figure 4–1 Installation direction of the VFD

4.2.3 Installation mode

The VFDs can be installed in two modes, depending on the different VFD dimensions:

Figure 4–2 Installation mode

(1) Mark the position of the installation hole. See Appendix C "Dimension drawings" for the position of installation hole;

(2) Mount the screws or bolts onto the designated position;

(3) Put the VFD on the wall;

(4) Tighten the fixing screws on the wall.

Note: Flange-mounting plate is a must for 004G/5R5P-110G/132P VFDs that adopt flange-mounting mode.

4.2.4 Single-unit installation

Figure 4–3 Single-unit installation

Note: The min. dimension of B and C is 100mm.

4.2.5 Multiple-unit installation

Figure 4–4 Parallel installation

Note:

1. When users install VFDs in different sizes, align the top of each VFD before installation for the convenience of future maintenance.

2. The min dimension of B and C is 100mm, and the dimention of D can be 0, that is zero-clearance parallel installation is supported.

4.2.6 Vertical installation

Figure 4–5 Vertical installation

Note: During vertical installation, users must install windshield, otherwise, the VFD will experience mutual interference, and the heat dissipation effect will be degraded.

4.2.7 Tilted installation

Figure 4–6 Tilted installation

Note: During tilted installation, it is a must to ensure the air inlet duct and air outlet duct are separated from each other to avoid mutual interference.
