BAKC Smart Shielding Solutions
BAKC Capital Group, LLC products have several solutions addressing the challenges of cutting and reattaching the VFD cable shield for low impedance operation, properly maintaining the common mode current return to the sourcing VFD. The Shield Adapter products are patented and recognized by UL.BAKC has over 30 years of experience installing VFDs.
Why Use the BAKC Shield Plate Adapter – Terminal Block Product?
The BAKC Cable Shield Plate Adapter – Terminal Block product is used when the shielded VFD cable between a VFD and its motor is required to be cut and re-terminated. A typical use for this product is in the electrical panel enclosure where convenient field termination of VFD shielded cable can be made with terminal block connections for the motor load and ground wires while maximizing the shield surface area continuity. It enhances plant safety, reduces downtime, and simplifies the VFD-shielded cable terminations shortening startup time.
A VFD naturally produces common mode current, which must return from the motor to the sourcing VFD to cancel out. Placing easy-to-connect terminal blocks to aid with startup and integration prevents this common mode current return. Failure to block common mode high-frequency “peak” currents will cause the currents to destroy sensitive equipment tied to your plant ground.
Having this common mode current on your protective earth ground grid is also a safety concern as the current can be high along with the voltage difference between your VFD and motor frame. Properly installed and 360 degrees terminated VFD shielded cable uses the shield’s surface area to allow the common mode current to return and isolate from sensitive areas easily. High-frequency common mode current will always find “surface area” to travel. The Shield Plate Adapter Terminal Block version is designed to allow high surface area termination cable clamping with low impedance surface area to allow the common mode current to return to the VFD as if the cable were not disrupted. Without the Shield Plate Adapter, making intermediate terminations with high inductive reactance wired pigtails, or removing the cable shield, will allow common mode current to find the paths of least impedance like your building steel which is your ground grid. The BAKC Plate Adapter Terminal Block solution helps ensure equipment performance, aids error-proof installation, and enhances personnel safety.
Why Choose BAKC Shield Plate Adapter – Terminal Block?
There are many reasons to choose the BAKC Shield Plate Adapter – Terminal Block. Here are some highlights:
- Isolation of high-frequency parasitic current from electrical back plate 50/60Hz protective earth
- Easily attaches to panel back plate with DIN Rail
- Range from 16AWG to 2AWG VFD Shielded Cable
- Used in electrical enclosures where cable intermediate termination is required for ease of VFD cable wiring into a terminal block
- Can be used with the Shield Head Adapter product with an output disconnect if multiple cable intermediate terminations are required
