The machine room had better be on the second floor or above. Otherwise, the machine room floor should be
600mm higher than the highest flood level ever recorded.
Make sure there are no cracks or holes in the wall and floor. If there are cable entries in the wall or window, take
proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which should be up to the
standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the machine room sealed.
The steel door is recommended for soundproofing.
Sulfur-containing materials are forbidden.
Pay attention to the location of the air conditioner. Keep the air conditioner from blowing wind straight toward the
device or blowing water drops from the window or air vent toward the device.
2.2.1 Ventilation
QSW-6200 should be placed at least 10 cm away from surrounding walls to effective ventilation and heat dissipation.
Cables should be bunched or put on the cable frame after being connected in order to prevent blocking the air intake.
2.2.2 Temperature and Humidity
The temperature and humidity in the room must be stable to ensure the device's proper functioning and prolong its service
life.
Continuous improper temperature and humidity will cause damage to the device.
High relative humidity will reduce the insulation of insulation materials and cause electric leakage. Sometimes it may lead
to changes in the mechanical characters of materials and rust metal components.
Low relative humidity will dry the insulation sheets and generate static electricity, which will damage the electric circuits of
the device.
High temperature will large affect the device's reliability, shorten its service life and accelerate its aging.
Temperature and humidity requirements of the QSW-6200 series are as follows:
Temperature
Relative Humidity
0
ºC to 50ºC
10% to 90%
The working temperature and humidity are measured 1.5 m above the ground and 0.4 m away from the front plat and
when the
chassis’ front and rear protective plates are removed.
2.2.3 Cleanness
Dust poses the top threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the use life of the equipment, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.
