3 Operation Overview
3.1 Start-up and initial preparation
3.1.1
Location
• Do not keep or operate the unit in a wet, moist, or dusty environment. Avoid expo-
sure to direct sunlight or heat from other sources.
• Do not allow the unit to come into contact with acidic vapours or liquids.
• The AT-10 plus should not be placed in the vicinity of X-ray or diathermy units,
large transformers or electric motors. It must also be positioned at least one meter
from the mains supply.
3.1.2
Connection of external cable assemblies and ancillary
equipment
1. Check the voltage setting (115V or 230V) (see page 43).
2. Connect the power cable at the rear of the unit. The Mains indicator lamp is lit.
Leave the AT-10 plus connected to the mains for 7 hours to fully charge the
battery.
3. Connect the patient cable (side panel).
4. Connect any ancillary and optional equipment (see page 15). These may include
the following:
– Ergometer (analogue or digital) for exercise testing
– Blood pressure unit
– Spiro sensor (for spirometry)
– External monitor
– Network cable
– External printer
3.1.3
Potential equalisation
The potential equalisation stud at the rear of the unit is used to equalise the ground
potential of the AT-10 plus to that of all mains powered equipment in the vicinity. Use
the hospital or building common ground. A yellow/green ground cable is supplied as
an option (Article number 2. 310 005).
V
Danger of electrical shock. Do not operate the unit if the earth connection is
suspect or if the mains lead is damaged or suspected of being damaged.
To avoid possible interference from the ergometer when carrying out an exercise test,
it is recommended that both the AT-10 plus and the ergometer are connected to the
same common ground.
V
To prevent the possibility of leakage current when an external printer, external
monitor, or ergo device is connected, always ensure that the mains lead (with
earth grounding connection), and / or the potential equalisation, is attached to the
AT-10 plus.
