Installation Preparation
To avoid personal injury and TGW damage, please read this chapter carefully before installation.
2.1 Installation Precautions
For your safety, please follow the precautions when TGWxE1-2G is installed and used.
Keep the site free from heat and humidity
Take precautions with use of high-voltage electricity
Please let an experienced or trained operator install and maintain the TGWxE1-2G
Wear a static discharge wrist strap
Ensure the proper electrical grounding of installed equipment
Properly connect the power cable to the TGWxE1-2G
Do not plug the power cable when in use
UPS is advised
2.2 Site Requirements
2.2.1 Temperature and Humidity
Check the temperature and humidity of the equipment room. To ensure normal operation and long service
life of the TGW gateway, the temperature and humidity in the room should be kept at the proper range.
The humidity in the equipment room should be kept between 10% and 90% (non-condensing). Abnormal
humidity conditions may cause problems to the TGW gateway:
Long term high humidity may lead to bad insulation and even cause electricity leakage, mechanical
property change and corrosion.
Low humidity is likely to leave captive screws too loose due to static electricity built up and the
insulation washer shrinkage.
The temperature in the equipment room should be kept between 0
℃
and 40
℃
. Abnormal temperature
conditions may cause problems to the gateway:
High temperature accelerates aging of electrical parts and insulation materials.
Low temperature, however, may destabilize the operation of the gateway.
2.2.2 Cleanliness
Dust is very harmful to the safe operation of the gateway. Dust that is adsorbed by static electricity acts as
an insulator, which not only affects the service life of the gateway but also leads to communication failure.
Therefore, the room of the gateway must be kept clean.
