2.1 Functional Principle

2.2 Mounting

The PW100 housing is mounted on a TS35 top-hat rail. The width of the housing is 6 horizontal pitches (6 HP)
on the rail and, due to the low height of 60 mm, not only fits into a control cabinet, but also in a meter cabinet
under the covers.
The device requires an external power supply of approx. 42VDC. We strongly recommend using our NT016
power supply. If the PW100 is operated with another power supply, the function of the PW100 may be dis-
turbed. The NT016 also has a height of 60 mm and a width of only two module unit (2 HP).
