3 Electrical safety
3.1 Positioning of the electrical equipment
Make sure that electrical equipment on the uni-cart, vexio-cart, pro-cart,
duo-cart, compact-cart, classic-cart or endo-cart carrier system does
not get wet.
Under no condition should you position the products, which may lead to
loss of their fluidness, over the electrical equipment or extension lead in
which fluidity may be permeate.
3.2 Energy column (compact-cart, classic-cart, endo-
cart) and vertical column (uni-cart, vexio-cart, pro-cart)
The socket strips or the cabling system are located in the left or right power
columns of classic-cart, compact-cart or endo-cart, with uni-cart and pro-
cart it is in the vertical column. The vexio-cart´s socket strips and cabling
system are located beneath the base (cabling can be routed through
optional cable ducts, which are attached laterally to the vertical column).
Power columns are located on the left and right behind the vertical extrusion
and permit optimum accommodation of the power equipment cables availab-
le. Do not drill holes in the power columns /
vertical columns because power cables may be located inside the columns.

3.3 Gases
Electrical equipment should not be operated in the vicinity of gases, e.g. flammable gas used in
anaesthesia or similar gases. The user is responsible for maintaining this requirement and for
compliance with IEC 60601-1-2 standard.
3.4 Equipotential bonding (POAG)
Equipotential bonding should be carried out for the uni-cart, pro-cart, classic-cart, compact-cart
or endo-cart carrier system with an isolating transformer. vexio-cart offers an optional POAG set
without isolating transformer. The equipotential bonding cable should be first connected to the base
of the uni-cart, vexio-cart, pro-cart, classic-cart, compact-cart or endo-cart carrier system and then
be connected to the equipotential bonding plug in the room. Next, connect the POAG supply cables
to the POAG pins of the multiple sockets and the appliance.
3.5 Isolating transformer – leakage current
The uni-cart, vexio-cart, pro-cart, duo-cart, compact-cart, classic-cart or endo-cart carrier
system is intended to provide a practical and mobile workstation for medical electrical equipment.
Total earth leakage currents must not exceed a maximum value of 0.5 mA so that the entire medical
electrical system can be compliant with IEC 60601-1. If the sum of the ground leakage currents
would exceed the tolerance range, the system must be supplied through a safety transformer.
If an isolating transformer is not mounted, the multiple socket strip / auxiliary socket strip system of
the uni-cart, pro-cart, duo-cart, compact-cart, classic-cart or endo-cart carrier system must not be
used to connect up equipment that is not in conformity with requirements for earth leakage currents
under IEC 60601-1.
If an isolating transformer is mounted, the total power uptake of all the connected units must
remain within the rated value for the isolating transformer.
3.6 Earth-leakage-guard (ELG)
The following descriptions are only applicable for the carrier systems in which the item
“isolating transformer with insulating monitor” is installed.
3.6.1 Control panel of the earth-leckage-guard (ELG)
At the devices with integrated-earth-leakage guard the evaluation unit is in the transformer
case, the separate control panel is placed in one of the shelves. Both components are connected
with an interface cord, which lays in one of the profiles.
ELECTRICAL SAFETY
EN

Control panel of the earth-leakage-guard (optional):
1 Power on control (green)
2 Signals exceeding dielectric resistance (yellow)
3 Signals exceeding temperature (yellow)
4 Reset-button for fault release
5 Test-button starting self-test function manually
3.6.2 Application requirements
The earth-leakage-guard monitors the dielectric resistance for equipment (where safety
isolation is necessary) which are connected to the isolation transformers. Simultaneously,
the temperature of the transformer is evaluated by a built-in thermal switch which responds
when triggered. The evaluation procedure is processor controlled.
3.6.3 Application requirements
Turn the main power switch of the isolating transformer to “ON”. Within 5 s the self-test of the ELG
is automatically activated. After the self-test of the ELG is concluded, the green LED (Power on
control) glows permanently. During operation this test is repeated (automatically) in a time cycle of
8 hours. This self-test may also be activated manually through the test-button.
The control procedure for the manual self-test is as follows:
• An insulation error is simulated, the yellow LED (signals exceeding dielectric resistance)
glows, a warn signal (2.4 kHz) is activated. Both signals stop after approx. 5 s.
• Following this, a temperature error is simulated. The yellow LED (signals exceeding
temperature) glows, a warn signal (2.4 kHz pulse tone) is activated. Both signals stop after
approx. 5 s.
An error situation is recognized as follows:
• In case of an insulation error, the yellow LED (signals exceeding dielectric resistance)
glows permanently, the warn signal with 2.4 kHz is activated permanently. The warn signal
can be deactivated through the reset-button for fault release. The LED glows until the error
is eliminated.
• If the earth-leakage-guard is turned “OFF” in the meantime and the error is not eliminated,
when turning the ELG back “ON” the above described procedure begins anew.
With the occurrence of an isolation error the acoustic and optical alarm stays activated
(even if the isolation error is corrected on its own) until deactivated through the fault release:
First activation of the fault release: acoustic alarm is deactivated
Second activation of the fault release: optical alarm is deactivated

ELECTRICAL SAFETY
• In case of a temperature error, the yellow LED (signals exceeding temperature) glows
permanently and the warn signal with 2.4 kHz is activated intermittent. The warn signal can be
deactivated through the reset-button for fault release. The LED glows until the error is
eliminated. If the earth-leakage-guard is turned “OFF” in the meantime and the error is not
eliminated, when turning the earth-leakage guard back ON the above described procedure
begins anew.
• Should an insulation error and a temperature error occur simultaneously, the dielectric
resistance fault has priority (acoustic).
Self test for the Earth-Leakage Guard
In addition to the manual self-test, during operation the earth-leakage-guard repeats the self-test
in a time cycle of 8 hours and each time the unit is turned “ON”.
From outside, you will not notice the self-test, the time period for this process is approx. 5 seconds.
In case of fault, the green LED (power on control) blinks in a frequency of 0.5 Hz and with the same
frequency an acoustic alarm is activated. The fault signal can not be deactivated through the reset-
button.
3.6.4 Trouble shooting
Do not attempt to repair on your own. Warranty will be invalid if unauthorized repair has been
carried out. Due to safety reasons repair and maintenance may only be done by the
manufacturer.
Please note:
For further technical data and information, please refer to the separate and comprehensive
instructions for use, enclosed with the product, isolating transformer and insulating monitor.
3.7 Cable connection
Users of the uni-cart, vexio-cart, pro-cart, duo-cart, compact-cart, classic-cart or endo-cart
carrier system without an isolating transformer must ensure that the detachment of the cable
plug connection between the cart’s multiple power outlet strip and devices can only occur using
tools. Our line of accessories includes a selection of covers for multiple power outlet strips.
3.8 Combination of equipment
The following should be observed for combination of equipment on the carrier system:
• Auxiliary equipment connected to analogue and digital interfaces of the equipment must
be certified in compliance with the relevant EN specifications (e. g. IEC 60950 for data-
processing equipment and IEC 60601-1 for medical electrical equipment).
• Furthermore, all configurations must comply with the valid version of the standard
IEC 60601-1. Anyone connecting additional equipment to the signal input or signal
output is a system configurer and is therefore responsible for ensuring compliance with the
valid version of the standard IEC 60601-1.
If you have any questions, you should contact your local dealer or technical services.
