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
lAll 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.
lCoaxial cables’ outer conductor and isolation layer should keep proper electric conducting with
the metal housing of device.
lGrounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.

FMUSER INTERNATIONAL GROUP INC. 广州市汉婷生物技术开发有限公司

lUsers should make sure the 2 ends of grounding wire well electric conducted and be antirust.
lIt is prohibited to use any other device as part of grounding electric circuit
lThe area of the conduction between grounding wire and device’s frame should be no less than
25mm
2
.
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 25mm
2
.
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.
lConnecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC power.
lConnecting 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.
FCaution:
Before connecting power cord to FUTV4502D DVB-S2 modulator, user should set the
power switch to “OFF”.
