Warning
Device is constructed for connection in 1-phase main alternating current and must be
installed according to norms valid in the state of application. Installation, connection and
setting can be done only by a person with an adequate electro-technical qualifi cation which
has read and understood this instruction manual and product functions. The device contains
protections against over-voltage peaks and disturbing elements in the supply main. Too
ensure correct function of these protection elements it is necessary to front-end other
protective elements of higher degree (A, B, C) and screening of disturbances of switched
devices (contactors, motors, inductive load etc.) as it is stated in a standard. Before you start
with installation, make sure that the device is not energized and that the main switch is OFF.
Do not install the device to the sources of excessive electromagnetic disturbances. By correct
installation, ensure good air circulation so the maximal allowed operational temperature
is not exceeded in case of permanent operation and higher ambient temperature. While
installing the device use screwdriver width approx. 2 mm. Keep in mind that this device is fully
electronic while installing. Correct function of the device is also depended on transportation,
storing and handling. In case you notice any signs of damage, deformation, malfunction or
missing piece, do not install this device and claim it at the seller. After operational life treat
the product as electronic waste.
Accessories
Any measuring probe suffi
ces. Due to constant contact with fl uid we recommend:
Measuring probes:
• Level probe SHR-1-M - brass probe, Level probe SHR-1-N - stainless steel probe
- probes designed for monitoring fl ooding
• Level probe SHR-2
- stainless steel probe certifi ed for drinking water, which in combination with an
adequate assessment device used for detecting levels e.g. in wells, boreholes, tanks
- in plastic case sealed with bushing P67
• Level probe SHR-3
- stainless steel designed for use in harsh and industrial environments, designed to be
secured to the wall or tank lid with screws.
• Three-wire cable D03VV-F 3x0.75/3.2
- cable for probes SHR-1 and SHR-2, 3x 0.75 mm
