Installation and Instrument Setup

4.2.1 Internal battery
• The HistoCore SPECTRA CV has a high-performance internal battery to bridge short-term power
failures (< 3 s.). This enables processing to continue without interruption during a short-term power
failure.
• The software detects if the power failure lasts longer than 3 sec. and initiates a controlled shutdown of
the instrument (
→
P. 136 – 8.2 Power failure scenario and instrument failure) .
Note
• The internal battery has to be recharged when initializing the instrument after a power failure.
The user is notified of the charging process by a note on the screen. Once the charging process has
finished, the information message goes away automatically and the software prompts the user to
check if there are any racks still in the instrument and to remove them by hand if necessary. The
user confirms the removal of the rack by pressing the Ok button. Then the instrument restarts.
• The internal battery has to be charged if the instrument has been disconnected from a power supply
for 4 weeks. For this purpose, connect the instrument to the socket and switch on the Main switch
(
→
Fig. 1- 8 ) . The charging time is approx. 2 hours.
4.2.2 Using an external uninterruptible power supply (UPS)
An interruption of processing can be avoided in the event of a temporary power failure by connecting
a battery-buffered uninterruptible power supply (UPS) ( → Fig. 6- 1 ).
The UPS should enable an output of at least 1100 VA for the duration of 10 minutes.
The UPS must be designed for operating voltage at the installation location. The connection is carried
out by connecting the HistoCore SPECTRA CV power cable to the UPS power output socket. The UPS is
connected to the power socket in the lab.

Warning
The UPS power cable must always remain in the power socket in the lab, even in the event of a power
outage. Otherwise grounding of the instrument cannot be ensured!
