FT-107 Weighing Terminal, Technical Manual, Rev. 1.0.0, August 2019 Page 11 of 46
4. INSTALLATION
PRECAUTION: Please read this section carefully before installation of the instrument. Applying the
recommendations in this section will increase your system reliability and its long-term performance.
Before starting the installation,
1. Select the weighing terminal location. Refer to recommendations in the following section.
2. Prepare the PE protective earth cable to grounding the indicator housing. The protective earth
should be as good as possible for scale reliability.
3. Prepare the power source near the weighing terminal.
4. Prepare the cabling tray, pipe etc. from platform to the weighing terminal.
4.1 Recommendations
4.1.1 Environment
Warning: Please care the following warnings for designing your operation area which will increase your
system reliability.
The weighing indicator should be placed clean area, not getting direct sun light if possible, with a temperature
between -10 ºC and +40 ºC, humidity not exceeding 85% non-condensing. All external cables should be
installed safely to avoid mechanical damages.
This instrument is very low-level signal measuring instrument. To avoid electrical noise, it should be separated
from equipment that produces electrical noise. The instrument body shall be connected to a good ground
against the electromagnetic disturbances. Load cell cable must be separated from other cables, if possible. If
there are noise-generating equipment such as heavy load switches, motor control equipment, inductive loads
etc., please be careful against the EMC interference. Connect parallel reverse diodes to the DC inductive
loads like relays, solenoids etc. to minimize voltage peaks on the DC power lines.
4.1.2 Cabling
All cables coming to the instrument shall be high quality and shielded. Distance from load cell cables, interface
cables and DC power supply cables to power line cables shall be minimum 50 cm. The separate cable tray
usage for these low signal level cables is strongly recommended.
Shields of the cables should be connected to the ground.
4.1.3 Cleaning
Warning: Disconnect the instrument from power source before start cleaning for your safety. Cover the
open glands.
FT-107 instrument is designed for using in wet, hygienic and harsh environment. To maintain the instrument,
never use harsh abrasive cleaners or solvents. Wipe the instrument with a soft cloth slightly dampened with
warm soapy water or with mild detergent.
4.1.4 Disposal
In conformance with the European Directive 2002/96 EC Waste Electrical and Electronic Equipment (WEEE),
this device may not be disposed of with domestic waste. This rule also applies to the non-EU countries,
according to their specific regulations. Please dispose of this product in accordance with local regulations at
