The 1597DINCOV4GY is the knockout-style low cover for the 35 mm and 70 mm wide DIN rail enclosures in its family. The series ordering table lists it as the knockout cover for the 1597DIN2GY 2 module and 1597DIN4GY 4 module enclosures, giving installers a cover position they can open up where wiring or components need to pass through.

It measures 1.37 in x 0.64 in x 0.4 in (35 mm x 16 mm x 10 mm), with a 34.70 mm (1.37 in) length on the accessory drawing. The part page lists the material as polycarbonate, PPE and PS, colour gray, with a UL94 V-0 flame rating and an IP20 rating.

Covers are sold individually, so a knockout cover can be fitted to one cover space while others take the closed (1597DINCOV1GY), oval (1597DINCOV2GY) or vented (1597DINCOV3GY) types. The 1597DIN2GY has 2 cover spaces and the 1597DIN4GY has 4. The enclosures snap together without hardware.

The 1597DINCOV4GY is shrink wrapped, REACH and RoHS compliant, UPC 623980318837. When opening knockouts or making other modifications, the manufacturer recommends clearing chips with an air blast rather than cutting or tapping fluid, and cautions against acetone, ketones, ethers, aromatic and chlorinated hydrocarbons and strong solvents.
