Information on performance level applications:
• The 24 V DC power supply to be used must be tested according to the
EN 60950-1 or EN 62368-1 standard / must meet the applicable PELV
(protective extra low voltage) or SELV (safety extra low voltage)
requirements (see Chapter 3.8.1 "Connecting the supply voltage 24 V
DC”, page 24, Chapter 8 "Technical Specifications POWER CHARGER
PC_ _”, page 77).
• A redundant release signal is required if the generator must comply
with the safety requirements of DIN EN 13849. To this end, the two
signals “Release +” and “Release -” must be transmitted via separate
switching paths; hardwiring of the two release signals +/- is prohibited
(see Chapter 3.10.1 "Analog interface Charging”, page 28, Chapter
3.10.2 "Analog interface Discharging”, page 30).
• Release analog interface
Be sure to connect the signals properly to avoid damaging the genera-
tor. Always use shielded cables as interface cables; the shield must be
contacted at both ends (see Chapter 3.10.1 "
Analog interface Charg-
ing”, page 28, Chapter 3.10.2 "Analog interface Discharging”, page 30).
• The enable signals for charging / discharging must be switched off at
least once a year for 400 ms or longer so that errors in the enabling
logic may be detected.
• The charging / discharging bars must be cleaned at least once a week
to ensure that they function properly (see Chapter 4.3 "Releasing the
high voltage”, page 41).
• The voltage at the input plugs of the 24 V DC supply voltage, the ana-
log interfaces for charging and discharging and the field bus interfaces
must not exceed 60 V DC (see Chapter 3.8.1 "Connecting the supply
voltage 24 V DC”, page 24, Chapter 8 "Technical Specifications
POWER CHARGER PC_ _”, page 77).
