HI 6020 Summing Box Diagram
The HI 6020 Summing box is available with a variety of options, including IT, trim pots (for non-Hardy load
cells) and a NEMA 4X enclosure in stainless steel, painted steel or fiberglass. The enclosure features a thick-
wall design with an interior seal for a long lasting, robust wash-down installation. Each box comes with six
packaged hole plugs and six cable grip fittings suitable for load cell cables with an outside diameter of 1/4 to
3/8 inches. The ATEX and IECEx (-EX models) are designed for installation with intrinsic barriers and do
not come with any glands or hole plugs.
A single HI 6020 Summing Box supports up to 4 load cells. To connect two HI 6020 Summing Boxes
together to support between 5 and 8 load cells, use the TB6 Auxiliary connection between boxes and order
one of the summing boxes with six holes.
The HI 6020 Junction Box is UL and CE compliant and is rated for installation in Hazardous Locations:
