1.3.3 Grounding and Shock Prevention PR 5410/00
The instrument must be connected to protective earth via a protective earth conductor (PE) in the power
connector. The power cable contains a protective earth conductor which must not be interrupted inside or
outside the unit (e.g., by using an extension cable that does not have a protective earth connection). The PE
conductor is connected to the back panel of the housing inside the instrument.
1.3.3.1 Grounding and Shock Prevention PR 5410/01
The back panel of the housing must be connected to protective earth.
1.3.4 Power Connection and Power Supply PR 5410/00
The unit does not have a power switch and is ready for operation immediately after connecting the supply
voltage. Safe interruption of both supply voltage conductors must be provided for, either by disconnecting
the power connector or using a separate switch. The unit is equipped with a wide range power supply and
covers AC systems with a frequency of 50 Hz/60 Hz and a voltage range of 100 VAC to 240 VAC +10%/-
15% automatically (without manual selection). The power supply is protected against short circuits and
overload, and switches off automatically in the event of failure.
When the electronic protection is triggered:
•
Disconnect the unit from all voltage sources and wait at least one minute.
•
Determine and eliminate the source of error.
•
Re-connect the unit to the supply voltage.
1.3.4.1 Power Connection 24 VDC PR5410/01
The version PR5410/01 is designed for 24 V direct current.
The supply is done with two screw terminals (- 24V +), the instrument is protected against
wrong polarity.
The instrument is protected by a fuse in the + conductor on the back panel of the housing.
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 Important
Note
Make sure that the construction of the instrument is not altered to the detriment of safety. In particular,
leakage paths, air gaps (of live parts) and insulating layers must not be reduced. Sartorius cannot be held
responsible for personal injury or property damage caused by an instrument repaired incorrectly by a user or
installer.
