2.2 Installation Site Requirements
The RG-S5750H series must be used indoors. To ensure its functioning and prolong its service life, the
installation site must meet the following requirements.
2.2.1 Ventilation
RG-S5750H 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 RG-S5750H series are as follows:
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.
Dust Particle (Particles/m

Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict
requirements; as such poisonous substances may accelerate the corrosion of the metal and the aging
