DIB-500 R4.1 Requirements concerning the operation room
Environment
An air-conditioning system can be used to control the temperature in the operation
room. The thermal dissipation loss of the product as well as of other technical equip-
ment operated in the operation room must be taken into consideration when controlling
the operating temperature. The maximum thermal dissipation loss corresponds to the
power consumption, refer to Tabelle 5.5 on page 30.
Responsibility of the operator
The use of an air conditioning system is advisable. The operating company is responsi-
ble for the proper installation and the operation of an appropriate air conditioning sys-
tem.
For information on alternatives to an air conditioning system, please revert to the serv-
ice partner responsible for your company.
4.2.2 Humidity
The following requirements must be met for being able to operate the product as
intended:
| The service room must be dry and closed to maintain a constant relative humidity of
50 %, if possible (recommended for slowing down the aging process of integrated
components).
| Unimpaired air supply to the equipment rack must be ensured.
The ventilation concept of the DIB-500 R4.1 provides for the optimum vertical ventila-
tion of the incorporated components inside the equipment rack. In this case, the air is
drawn in through the perforated equipment rack door and all the dirt and dust particles
are filtered out via the ventilator unit. Subsequently, the air is discharged through the top
of the perforated equipment rack door.
4.2.3 Dust concentration
The product was developed for use in a municipal industrial area. The average dust
concentration per year in a municipal industrial area amounts to a value of up to
200 µg/m³. The dust concentration in the operation room of the product must not
exceed this value.
Operation rooms that are not completely closed require an appropriate housing.
To ensure a minor dust concentration, the use of an overpressure system for the opera-
tion room is advisable.
Responsibility of the operating company
The use of an overpressure system is advisable. The operating company is responsible
for the proper installation and the operation of an appropriate overpressure system.
