Chapter 2 Hardware Installation
This chapter describes the hardware installation of the RDU501, including installation preparation, installation of the
RDU501 main unit, installation of expansion cards and sensors and other accessories.
2.1 Installation Preparation
2.1.1 Cautions
When installing the RDU501, pay attention to the following items to avoid injury to people and device damage caused
by accidents.
All installation operations on the RDU501 must be performed after disconnecting the power supply.
Ensure that the external device is connected to the correct RDU501 port.
The installer needs to wear an anti-static wrist during the installation process.
Properly route the cables to ensure that no heavy objects are pressed on the power cord. Do not step on the cable.
2.1.2 Environmental Requirements
Running environment
The RDU501 must be installed indoors. See Table 1-16 for specific requirements.
Anti ESD
In order to minimize the effects of static electricity, the following measures are required:
Maintain proper temperature and humidity in the device room (see Table 1-16)
Before the human body touches the circuit board, wear an anti-static wrist strap and wear anti-static clothes. If there
is no anti-static wrist and anti-static overalls on site, rinse your hands with water and dry them.
Anti disturbance
For anti disturbance, the following measures are required:
Avoid using the RDU501 operating ground with the grounding device or lightning protection grounding device of the
power device.
Keep away from strong power radio launchers, radar launchers, high frequency and high current devices.
Use electromagnetic shielding if necessary.
2.1.3 Space requirements
Place the RDU501 away from heat sources
It is recommended to install the RDU501 in a 19-inch standard cabinet. Leave at least 10 mm of space around the
device to ensure sufficient space for heat dissipation.
