PR 5211 Instrument Manual Safety Hints
Sartorius EN-7
1.4.5 Failure and Excessive Stress
If the instrument is suspected of being unsafe, shut it down and protect it against accidental operation. This
is the case when the unit:
- is physically damaged,
- does not function any more,
- is stressed beyond the tolerable limits (e.g. during storage, transport).
1.4.6 Fuse
The instrument has got no fuse to be exchanged. The load cell supply is protected against short circuit by
multifuse elements. If the load cell supply switches off, disconnect the device from power. Search for the
reason and eliminate it. After a cooling down period of about 3 minutes the power can be switched on
again.
1.4.7 EMC-Compliant Installation
- Use only screened data cables.
- Connect screens on both ends with ground.
- Keep unscreened cable ends short.
- Connect screen rail to cabinet / housing with
low impedance.
- Use metal or metallized connector housings.
- Establish equipotential bonding between
instruments/system modules (Mandatory for
Ex-applications).
- Use standard reference potential.
- Connect mounting rail to protective earth.
- Install measure and data cables separately from
power cables.
