Safety Instructions
Combics weighing platforms have been constructed in accordance with the European
Directives as well as international regulations and standards for electrical equipment,
electromagnetic compatibility and safety.
- Do not expose the weighing platform unnecessarily to aggressive chemical vapors or to
extreme temperatures, moisture, shocks, or vibration.
- Do not use a Combics weighing platform in a Zone 0, 1, 20 or 22 hazardous area or a
Class 1, Division 1 or 2 hazardous location.
- You may operate any Combics weighing platform in a Zone 2 or 11 hazardous area.
- Avoid exposing the weighing platform to static electricity; be sure to connect the
equipotential bonding conductor to the junction box.
- Observe the particular IP protection rating of your scale: IP65 protection rating for
non-stainless steel models; IP67 protection rating for stainless steel models. First digit:
rating 6 indicates resistance to penetration by dust particles of a specified size. Second
digit: rating 5 indicates resistance to splashes of water as well as washdown-resistance.
Rating 7 indicates resistance to penetration by water during 30-minute immersion up
to a depth of 1 meter (~ 3¼ feet). The particular IP protection rating for the weighing
platforms is ensured only if the rubber gasket is installed on the junction box and all
cable gland screw fasteners are tightened securely.
Improper installation will result in forfeiture of all claims under the manufacturer´s
warranty.
- The junction box may be opened only by authorized service technicians who have been
trained by Sartorius and who follow Sartorius’ standard operating procedures for
maintenance and repair.
- If you see any indication that the weighing platform cannot be operated safely (for
example, because of equipment damage), turn off the platform and lock it in a secure
place so that it cannot be used for the time being.
- Suspension points are provided on platforms of a size of 36 x 36 inches or larger. If
you need to transport or lift the scale or load plate using a crane, do not step
underneath the suspended scale or load plate. Be sure to observe the corresponding
safety rules and regulations for prevention of accidents. Do not damage the junction
box or the load receptor during transportation.
- If you use suction lifting equipment to lift the load plate, always wear globes, hardtoed safety boots and protective clothing. Warning! This procedure can cause personal
injury! Therefore, only reliable staff who are qualified to perform such work are
allowed to use suction lifting equipment.
- Always make sure the weighing platform is disconnected from AC power before
performing any installation, cleaning, maintenance or repair work.
- Check the pin assignment if you use cables purchased from a different manufacturer.
Before connecting such a cable to Sartorius equipment, check the pin assignment on
the corresponding wiring diagram or chart and disconnect any wires that are identified
differently from those specified by Sartorius. The operator shall be solely responsible
for any damage or injuries that may occur when using cables not supplied by Sartorius.
