Environmental requirements / room configuration
The bearing capacity of floor and ceiling in the building must be higher than the weight of the machine. An authorized
body of the operator must certify the bearing capacity for the h/p/cosmos device.
Calculation according to DIN EN 1991-1-1
Substitutional load to floor:
(weight of (max. weight of subject x dynamic factor 1.5)) / (length x width of device)
example pulsar 3p (3.85 kN + 2.0 kN x 1.5) / (2.5 m x 1.05 m) = 2.6 kN/m
2
Load to floor on each support:
(weight of device x weight of subject x dynamic factor 1.5) / number of supports
example pulsar 3p (3.85 kN + 2.0 kN x 1.5) / 4 = 1.6 kN
Note: Usually the bearing capacity data of the building are indicated in the static load, so that static load of the building
and static load of the treadmill, including subject should be compared.
Running machines are not to be used in medically utilized rooms with a danger of explosions or in easily inflammable
atmospheres. The devices must not be installed near to e.g. an x-ray device, motors or transformers with high voltage
connection, as the electric and magnetic interference can falsify measurements or even render them impossible. High
voltage lines must be avoided nearby the device. h/p/cosmos electrical devices with mains connections must neither be
used in wet and humid areas (e.g. swimming pools, saunas, etc.) nor in environmental chambers. If not stated otherwise
in the delivery information, h/p/cosmos devices are designed for operation in normal climatic surroundings:
Temperature:
+ 10° ... + 50°C
Relative humidity:
30 ... 70 % (non condensing!)
Air pressure:
700 ... 1060 mbar
Maximum operating altitude: approx. 10,000 feet (3000 m), without pressurization
The running machine should be protected from high humidity. Vents are not to be covered, as this would hinder the air
circulation.
The surroundings of the patient/subject must have a gap of 1.5 m as required by the norm EN 60601-1.
Electrical equipment [3] and a subject [1] must never be touched by the doctor or trainer [2] at
the same time.
Casing and cover:
Parts of non-medical electric devices within the surrounding of the subject, which, after having taken off the
coverings etc. without the use of tools for a routine maintenance etc., are in touchable reach, have to operate with
a voltage that does not exceed 25 volt alternate voltage and 60 volt direct voltage, which is produced by a
separate source as described in IEC 60601-1. According to this example the leakage current would flow from the
electric device to the earthened subject via the trainer/doctor.
