1.4.2 Opening the Instrument
Danger! High Voltage!
Working on the instrument while it is switched on may have life-threatening
consequences.
Disconnect the instrument from the supply voltage. Any time covers or parts are
removed; live parts or terminals may be exposed. Capacitors in the unit may still be
charged also after disconnecting the unit from all voltage sources.
This instrument contains electrostatically sensitive components. For this reason, an equipotential bonding
conductor must be connected when working on the open instrument (antistatic protection).
1.4.3 Connection of a protective earth conductor to PR 5230
1.4.3.1 Version 230 V AC
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
instrument. The PE conductor is connected to the housing inside the instrument.
1.4.3.2 Version 24 V DC
The instrument must be connected to the protective earth conductor. The connection can be established via
the housing side wall.
1.4.4 Power Connection PR 5230
The instrument does not have a power switch and is ready for operation immediately after connecting the
supply voltage.
1.4.4.1 Version 230 V AC
Safe interruption of both supply voltage conductors must be provided for, either by
disconnecting the power connector or using a separate switch.
The instrument 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 V AC to 240 V AC +10 %/-15 %
automatically (without manual selection). The power supply is protected against short
circuits.
1.4.4.2 Version 24 V DC
This version is designed for 24 V direct current.
The supply is done with a 3-pin connector (PE/+/-). The instrument is protected against
wrong polarity.
