Safety Information PR 5220 Operating Manual
8 Sartorius
1.3.3 Protective Earth
Connection to protective earth must be performed via the mounting rail.
1.3.4 Supply Voltage Connection
The supply voltage is 24V DC +10% / -15%.
Max. power consumption of /00 version: 6.5 W; /01 and /04 version: 8.5 W
For connection to 230 / 115 V AC, an external power supply (e.g. Sartorius
PR 1624/00 or Phoenix Mini Power) is required.
1.3.5 Failure and Excessive Stress
If there is any reason to assume that safe operation of the instrument is no longer ensured, shut it down
and make sure it cannot be used. Safe operation is no longer ensured if any of the following is true:
- The instrument is physically damaged
- The instrument does not function
- The instrument has been subjected to stresses beyond the tolerance limits (e.g., during storage or
transport).
1.3.6 Fuse
This instrument does not have a replacable fuse. The load cell supply voltage is protected against short
circuit. In case of failure of the load cell supply voltage, disconnect the instrument from the supply voltage,
determine the cause and take remedial measures. Subsequently, the supply voltage can be switched on again.

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
Screen clamp (z.B. Phoenix SK8-D)
Rail connection (z.B. Phoenix AB-SK 65D)
Mounting rail (34mm)
Screen rail (e.g. Phoenix NLS-CU 3/10)
