14.
During installation, take suitable steps to prevent stray electrical interference (e.g. due to
magnetic fields). Keep any voltage transients away from the device.
15.
The indicator (indicator of the complete scale) should be installed so that there is only a low risk
of mechanical danger to the IP protection. The IP protection rating of the device is IP6x according
to EN 60529 / IEC 60529. The device is designed for clean environments and must be handled
carefully according to the IP protection rating.
16.
The power connection must be made in accordance with the regulations applicable in the country
of operation. A correct power connection must be ensured. The power supply cable should be
protected against damage and properly connected to the power supply (100 - 240 VAC, ± 10%,
50-60Hz) or 24 VDC (± 10%) for Option L8. The indicator and/or complete scale is approved for
circuits up to 1500 A. Only use the power supply connection cable in the hazardous area with a
suitable and approved explosion-protected plug. Alternatively: Protect connector from being
disconnected or attach the power supply connection cable directly. Be sure to provide a suitable
emergency shut-off switch.
17.
Avoid generating static electricity. Only use a damp cloth to clean the device. This is especially
true when using a dust cover. The equipment operator assumes responsibility for preventing any
risks caused by electrostatic charging.
18.
If cables are connected subsequently, make sure that the connections are not corroded. The
grounding conductor of a mains connection cable must have the same cross section as the
current-carrying wires (N and L).
19.
All external cables (even cables between load cells / weigh cells and connection box / junction
box) are only suitable for fixed placement and must be laid fixed. Otherwise, use screwed
connections designed according to EN60079-0 and rounded at an angle of 75º (minimum) and a
radius at least equal to one-quarter of the diameter of the cables, but without exceeding 3 mm.
20.
Cables from third-party manufacturers (subject to the user's responsibility) must be tested for
suitability according to Appendix A EN 60079-0. Pay attention to the pin assignment. Pay
attention to the wiring diagram. Remove unneeded connections.
21.
Unused openings must be sealed using suitable cover caps (dummy plugs) to ensure their IP
protection rating. Do not remove while it is carrying current.
22.
When using external devices in Zone 2 hazardous areas, pay attention to the gas group and
temperature class. The outputs must include the Ex nA electrical circuits. Pay attention to the
maximum surface temperature and group for Zone 22.
23.
Chemicals that can attack housing gaskets and cable sheathings must be kept away from the
device. These include oil, grease, benzine, acetone, and ozone. If you are uncertain, contact the
manufacturer.
24.
The installation must be inspected for correct function and safety by a trained and qualified
person at appropriate intervals.
25.
If the installation does not operate properly, disconnect it from the supply voltage immediately
and secure it against further use.
26.
In the event of repair, use only original spare parts supplied by the manufacturer.
27.
Any modifications to the instrument (except by persons authorized by Sartorius) cause loss of
conformity for use in Zone 2 and Zone 22 explosion-risk areas and invalidate all guarantee
claims. Similarly, the device may only be opened by qualified and authorized personnel.
28.
Modifications (also those by Sartorius personnel) are subject to written approval.
29.
These instructions are given in addition to those in the instruction manuals and do not release the
operator from his responsibilities for the installation, operation and inspection of the equipment in
compliance with any applicable regulations in the country of use.
