5 Safety information for the batteries (#1533137)
Handling on/in
operating table
24
The TruSystem 7000 operating table contains two lithium ion
batteries. Because of their size (number of individual cells plugged
in, amount of lithium contained), they are classified as a hazardous
material. There is a risk of explosion in case of fire. As a result, there
are legal ordinances regarding the handling, deployment, and
installation of this type of battery.
The lithium ion batteries were specially developed by
Trumpf Medical. An electronic protective circuit on a circuit board
in the housing monitors the threshold values of the current / voltage
data. The electrical connection outward is provided through a
7W2 D-Sub socket.
