3.2.1 Installation environment
The installation environment is the safeguard for the full play and long-term stable function of the VFD. Check the installation environment as followings:
Environment | Conditions |
Installation site | Indoor |
Environment temperature | -10–+50°C If the ambient temperature of the VFD is above 40°C, derate 1% for every additional 1°C. It is not recommended to use the VFD if the ambient temperature is above 50°C. In order to improve the reliability of the device, do not use the VFD if the ambient temperature changes frequently. Please provide cooling fan or air conditioner to control the internal ambient temperature below the required one if the VFD is used in a close space such as in the control cabinet. When the temperature is too low, if the VFD needs to restart to run after a long stop, it is necessary to provide an external heating device to increase the internal temperature, otherwise damage to the devices may occur. |
Humidity | RH≤90% No condensation is allowed. The maximum relative humility should be equal to or less than 60% in corrosive air. |
Storage temperature | -30–+60°C |
Running environment condition | The installation site of the VFD should: keep away from the electromagnetic radiation source; keep away from contaminative air, such as corrosive gas, oil mist and flammable gas; ensure foreign objects, such as metal power, dust, oil, water cannot enter into the VFD (do not install the VFD on the flammable materials such as wood); keep away from direct sunlight, oil mist, steam and vibration environment. |
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 | ≤ 5.88m/s2 (0.6g) |
Installation direction | The VFD should be installed upright to ensure the cooling effect. |
Note:
Goodrive300 series VFDs should be installed in a clean and ventilated environment according to enclosure classification.
Cooling air must be clean without corrosive gas or electrically conductive dust.
3.2.2 Installation direction
The VFD may be installed on the wall or in a cabinet.
The VFD must be installed upright. Check the installation site according to the requirements below. Refer to Appendix C "Product dimensions" for frame details.
Figure 3‑1 Installation direction of the VFD
3.2.3 Installation mode
The VFD can be installed in three different ways, depending on the frame size:
Wall mounting
Figure 3‑2 Wall mounting
(1) Mark the hole location. The location of the holes is shown in Appendix C "Product dimensions".
(2) Fix the screws or bolts to the marked locations.
(3) Put the VFD against the wall.
(4) Tighten the screws in the wall securely.
3.2.4 Installation of one VFD
Figure 3‑3 Stand-alone installation
Note: The minimum space of B and C is 100 mm.
3.2.5 Installation of multiple VFDs
Figure 3‑4 Parallel installation
Note:
Before installing the different sizes VFDs, please align their top position for the convenience of later maintenance.
The minimum space of B, D and C is 100 mm.
3.2.6 Vertical installation
Figure 3‑5 Vertical installation
Note: Windscreen should be installed in vertical installation to prevent mutual impact and insufficient cooling.
