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.
2.1.4 Installation Tools
The installation tools are shown in Table 2-1.

2.2 Install RDU501 Main Unit
2.2.1 Mechanical installation
The RDU501 main unit is installed in a cabinet.
Installation procedures:
1. Make sure that the installation cabinet is fixed and there are no obstacles inside or outside the cabinet.
2. Fix the front mounting ears on both sides of the RDU501 main unit with the attached M4 screws, and then install
the rear guide rails and mounting ears on both sides of the RDU501 main unit, as shown in Figure 2-1 and
Figure 2-2.

3. Use the M6 floating nut and M6 screw to fix the RDU501 main unit to the rack through the mounting ears on both
sides.
2.2.2 Electrical connection
Electrical connection procedures of RDU501 main unit:
1. Remove the power cable from the RDU501. Connect one end to the power input port of the RDU501 main unit and
clip the anti-break-away kit shown in Figure 2-3.

Note
The RDU501 main unit provides dual backup power supply, which can be either one-way or two-way. Input voltage: 100Vac to
240Vac, frequency: 50/60Hz.
2.3 Install Accessories of Expansion Card and Sensor
Note
The EXP8COM/EXP8DIAI/EXP8DOAO/EXP2DI6DO expansion card and SFP module are optional accessories, and users can
choose whether to purchase or install.
2.3.1 Install expansion card
The expansion cards include EXP8COM, EXP8DIAI, EXP8DOAO and EXP2DI6DO. The installation procedures are
as follows:
Remove the baffles of the expansion slots (Slot1, Slot2, Slot3, or Slot4) on the front panel of the RDU501. Insert the
expansion card into the expansion slot of the RDU501 and tighten the screws on both sides, as shown in Figure 2-4.

2.3.2 Install intelligent sensors
The intelligent sensors include: IRM-S01T intelligent temperature sensor (IRM-S01T), IRM-S02TH intelligent
temperature and humidity sensor (IRM-S02TH), IRM- S04DI Phoenix Interface Intelligent Digital Input Sensor (IRM-
S04DI for short), IRM-S04DIF RJ45 Interface Intelligent Digital Input Sensor (IRM-S04DIF) and IRM-S04DO Phoenix
Interface Intelligent Digital Output Sensor (IRM-S04DO) , as shown in Figure 2-5.
