Power Supply
The operating table electronics monitors the external and internal
power supplies. If the operating table is not in use for an extended
period, the batteries should be recharged periodically to preserve
the battery service life. A charging interval of 1 month is
recommended.
8.1
Internal power supply
Two lithium ion batteries provide the internal power supply. With the
set of batteries charged, use of the electric operating table functions
is guaranteed for 16 hours (total duration of movement for electrical
functions). The electrical functions on the operating table are
blocked when the rechargeable battery set is discharged or almost
completely discharged. In this case, the external power supply must
be connected.
The battery charge status can be seen on the indicator [a1] on the
column keypad. Observe the indicator while using the operating
table.
8.2
External power supply (line connection)
The operating table external power supply is provided by the line
power in the room. When connected to line power, there are no
limitations on the use of electrically powered table functions.
CAUTION!
Risk of personal injury. Hazard to the patient!
An extension cord cannot be used with the power cable at the
operating table, otherwise, in case of a fault, the permitted patient
leakage current threshold for cardiac surgery (applied part CF
according to IEC 60601–1) will be exceeded. The fault occurs
when the protective conductor is interrupted by a damaged power
cable. The operating table must only be connected to the power
grid using the original power cord from Trumpf Medical.
In addition, the supply voltage must be respected. The operating
table must only be connected to the supply voltage indicated on
the nameplate.
