Chapter 2 Installation Guide
2.1 Acquisition Check
When user opens the package of the device, it is necessary to check items according to
packing list. Normally it should include the following items:
HP8516T 8 CH Mux DVB-T Modulator 1pcs
User’s Manual 1pcs
RF/Loopout Cables 7pcs
Power Cord 1pcs
2.2 Installation Preparation
When users install device, please follow the below steps. The details of installation will
be described at the rest part of this chapter. Users can also refer rear panel chart during
the installation.
The main content of this chapter including:
Checking the possible device missing or damage during the transportation
Preparing relevant environment for installation

Item Requirement
Machine Hall Space
When user installs machine frame array in one machine
hall, the distance between 2 rows of machine frames
should be 1.2~1.5m and the distance against wall should
be no less than 0.8m.
Machine Hall Floor
Electric Isolation, Dust Free
Volume resistivity of ground anti-static material:
1X107~1X1010Ω，Grounding current limiting resistance:
1M (Floor bearing should be greater than 450Kg/㎡)
Environment
Temperature
5~40℃(sustainable )，0~45℃(short time)，
installing air-conditioning is recommended
Relative Humidity 20%~80% sustainable 10%~90% short time
Pressure 86~105KPa
Door & Window Installing rubber strip for sealing door-gaps and dual
level glasses for window
Wall It can be covered with wallpaper, or brightness less paint.
Fire Protection Fire alarm system and extinguisher
Power
Requiring device power, air-conditioning power and
lighting power are independent to each other. Device
power requires AC power 100-240V 50-60Hz. Please
carefully check before running.
2.2.3 Grounding Requirement
All function modules’ good grounding is the basis of reliability and stability of
devices. Also, they are the most important guarantee of lightning arresting and
interference rejection. Therefore, the system must follow this rule.
Coaxial cables outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high
frequency impedance, and the grounding wire must be as thick and short as
possible.
Users should make sure the 2 ends of grounding wire well electric conducted and
HP8516T 8 CH Mux DVB-T Modulator User’s Manual
7
be antirust.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be
no less than 25mm2.
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strip. The
grounding wire should be as short as possible and avoid circling. The area of the
conduction between grounding wire and grounding strip should be no less than 25mm2.
2.2.5 Device Grounding
Connecting the device’s grounding rod to frame’s grounding pole with copper wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel, and the
power switch, fuse, power supply socket is just beside ,whose order goes like this,
power switch is on the left ,power supply socket is on the right and the fuse is just
between them.
Connecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC
power.
Connecting Grounding Wire
When the device solely connects to protective ground, it should adopt independent
way, say, share the same ground with other devices. When the device adopts united
way, the grounding resistance should be smaller than 1Ω.
Caution:
Before connecting power cord to
HP8516T 8 CH Mux DVB-T Modulator, user
should set the power switch to “OFF”.
2.4 Signal Cable Connection
The signal connections include the connection of input signal cable and the connection

of output signal cable. The details are as follows:
