5 Safety information for the batteries (#1533137)
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.
Handling on/in
operating table
The battery is connected using cable W134 (#1538234) for
battery 1 and W172 (#1538235) for battery 2. The battery is
directly connected or disconnected using the corresponding
connection cable in the operating table. There are no special
measures, such as a connection sequence on the power supply. A
