NPU Mechanical Design
The NPU is packaged in a plastic box for assembly on a mounting plate TS 35 (DIN rail 35 mm).
NPU could be also mounted with two screws M4 (with span 60mm) to a mounting board. For this
alternative it is necessary to take out and turn clamp on the rare side of the box.
NPU has four operating push-buttons. The SET button (for settings) can be protected with cover (fixed by
wire with two seals). The NPU has an LED display (four digits) and 10 LEDs for indication. Dimensions are
on the figure.
