Installation
STULZ UltraSonic -System for duct humidification ENS 14 A - 18 A-
Example:
A ENS 14 A is installed and the associated switch gear cabinet is situated at a distance of 5 m. The wir
-
ing will therefore have a cable cross-section of 2.5 mm
2
. Is this installation compliant with regulations?
Given:
i = 1,94 V (4%)
y = 56,2 [m / (
Ω
x mm
2
)]
A = 2,5 mm
2
I = 15,63 A
i x 56,2
[m / (
Ω
x mm
2
)]
x A
L =
2 x I
1,92 V x 56,2 m x 2,5 mm
2
=
2 x 15,63 A x
Ω
/mm

= 8,63 m > 5 m
CAUTION
Larger cable cross-sections.
If larger cable cross-sections are used, different terminals must be employed!
Note
CAUTION
Short cable routes.
We urgently recommend keeping cable routes as short as possible, and extending the supplied cables
only in exceptional cases.
Note
CAUTION
Limited capacity.
If the voltage drops by more than 4%, the capacity of the unit is limited!
