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.
Feeding, signaling and control cables are connected from below, on the side or
from above.
