 1 The dimensions of a definite ШУ-ЗА cabinet/panel are determined by the parameters of built-in units,

design documentation and an order sheet.


At the place of its installation ШУ-ЗА panels are stationary and intended for

indoor operation, in the absence of vibrations or strokes. Environment should

be explosive-free, should contain no current-conducting dust, aggressive gases

and vapors in the concentrations reducing an insulation level within prohibitive

limits.

A cabinet/panel body is manufactured of thin-wall perforated sections.

The door (in the cabinet case) and walls are made of a steel sheet and may

be solid or may be glass covered. All metal structures are painted with a powder

paint. The front door (the front panel part) locates equipment operation displays,

control devices, control instruments.
