3.2 Mounng Indicang transmier
The Indicating transmitter is mounted indoors, it should preferably be located in an
easily accessible, well lit and dry area. Avoid vibration. Take interconnecting cable
length into consideration when choosing the mounting location.
The enclosure is mounted vertically on an upright surface (wall) using four mounting
feet, see Figure 3.3. The LCD is best viewed when approximately on the eye level of
the user.
In sanitary installations, K-Patents recommends using a DTR with stainless steel en-
closure. If standard polycarbonate enclosure is used, it should be installed as remotely
as practical from the product areas or connections.
Important: Do not drill mounting holes in the enclosure as that will affect the pro-
tection class of the enclosure and damage the electronics.

and mounng feet measures
Note: The LCD display has an operating temperature range of 0–50 °C and a storage
temperature range of -20–60 °C.
Important: The DTR does not have a built-in power switch. The system is always
powered on when connected to a power source. K-Patents recommends mounting an
external power switch to control the DTR’s power supply, Figure 3.6.
3.3 Electrical connecons
3.3.1 Interconnecng cable
The cable contains a pair of twisted signal wires (1, 2) and a cable shield (3) (see
Section 3.3.2 and Figure 3.7). Standard delivery is 10 meters (33 feet) of cable. The
maximum length of an interconnecting cable is 200 m (660 ft). The signal wires (1, 2)
are interchangeable (non-polarized). The cable shield is connected to the protective
earth at the Indicating transmitter.
