VFD Panel

Looking to buy a VFD Panel? Then you might know how crucial it is for almost every industry. It’s a prime component for your manufacturing plant and can bring down the entire factory in seconds. So, it’s better to have all the knowledge before the deliverer shows up.

You should know, 50% of the total VDF malfunctions take place in lieu of wrongful installation. So, here are factors you might consider while installing a Variable Frequency Drive Panel 

Determining the Right Place of the Installation:

Generally, people won’t think about this a lot, they pick an empty space and go on board with the installation. In the real world, it’s the last thing you want to do. Your plant’s atmosphere can be harsh and hot, both things meddle with the healthy functioning of the panel. So, choose a spot where the temperature goes no more than 40 degree Celsius. Also, make sure that your panel is away from the direct sunlight. If you are afraid you cannot manage the same, make arrangements to cool down the spot.

Keep the Manual:

Manuals are printed to assist the user, and what the user do? They throw them off and improvise and in the hour of need, the manual is nowhere to be found. So, keep it handy and don’t opt for the hit and trial approach.

Supply Line Quality:

Probably the most important and calculable factor with your VFD panels. The voltage flow should not deviate 10% plus or minus, the panel will trip to keep the equipment safe in such situations. You should keep track of the voltage and plan for the times when the voltage is inadequate.

Fault Protection:

Many large hp panels face problems of short circuits, while the story is different for smaller ones. They are under 5 hp and require an external fuse. These fuses should be properly sized and match the panel requirements. You can have a good chat about fuses with the installation guy or refer to the manual for the same. It’s very important that you blend the right fuse with the VPF to secure the semiconductor if faced by a fault.

Motor Protection:

Every motor requires an overload protection. The normal drill is to use a motor overcurrent relay system which will protect the 3 phases and avoid single phasing. The system will detect any overcurrent conditions but won’t do anything for over-heating.

The motor often used at low speeds may encounter a thermal breakdown. This happens due to the motor running on reduced speeds faced with a reduced cooling effect. The thermal sensing of motor winding is the only resort. This is linked with the VFP’s main circuit and showed in the display.

As a buyer, you need to evaluate what type of use would you need and buy the right motor protection. It’s important for the long life of your motor setup.

Electrical Connections:

Your installation and choice of local connections should be in light of the NEC norms and the seller.
