Additional information
IMPORTANT TO KNOW
The use of countersunk or blind-hole fasteners for Group I equipment is necessary to protect the heads of the components from impact. Hexagon-head cap screws for Group II equipment must be countersunk or used in blind holes, or their impact protection must be provided by the equipment design.

EXAMPLES OF EQUIPMENT LOCATION INSIDE THE SHORVA…-O BOXES
Typical electrical components installed in boxesinclude terminal cluminaires, circuit breakers, residual-current devices (RCDs), residual-current circuit breakers, contactors, circuit breakers, fuses, ballast chokes, transformers, relays and timers, starters, IT components, remote-controlled switches, active/passive spark-proof barriers, and Ni-Cd batteries. The electrical equipment and components supplied with the boxes are from leading manufacturers. Other equipment options are available upon special request.
EXPLOSION-PROOF FRAMES IIGb / IIIDb FOR MODULAR DESIGN
When designing cabinets, situations arise where the dimensions of the existing enclosures are insufficient to accommodate the equipment. In this case, the cabinet can be divided into individual modules, connected either by metal sleeves or conduit.
The use of relatively small modules reduces the cabinet's size, weight, and cost. Furthermore, the large surface area allows for accessible cable glands, significantly simplifying installation.
Modular cabinets are installed on a frame/FRAMEmade of galvanized steel (cold or hot galvanized), and on request, made of stainless steel.
The frames are manufactured for wall or floor mounting and are classified as friction-insincerely safe non-electrical equipment with explosion protection levels IIGb and IIIDb.
