Always make sure to connect all coaxial cables and network cables to
DPU
before connecting the power cable.
Ground the DPU enclosure in the DPU earth terminal with coaxial network earth terminal. This
must
be done to
avoid electrical shock and to avoid damage to the unit. Ground loops might build up enough electrical charge
to give an electrical shock if not properly connected before connecting the power cord. Make sure to connect
the CATV amplifier’s ground connection to the
DPU
unit if both the CATV amplifier and
DPU
are installed in the
same physical location.
3.1
When Using the DPU
The
DPU
is designed to operate on 100/230VAC or 13-25 VDC. If the unit is
not
powered using the power
supply delivered with the
DPU
, but in any other way directly or indirectly with 13-25 VDC, a 3 A fuse
must be
fitted to the DC power cable.
Warranty may be void or limited due to use of other than recommended power
supply.
Please observe the following:
•
Do not stick any foreign objects, like metal or flammable objects into the
DPU
, as this can cause fire or
electric shock.
•
Do not remove the inner cover sheets or modify them in any way.
-
High voltages which can cause severe electric shocks are present inside the
DPU
enclosure. For any
inspection, adjustment, and repair work please contact the local InCoax dealer. The warranty may be
void if the cover to the high voltage DPU area has been opened.
-
Never attempt to repair this product yourself. Improper repair work can be dangerous. Never
disassemble or modify this product. Tampering with this product may result in injury or fire.
The warranty is void if the cover to the low voltage DPU area has been opened.
•
Do not handle the power supply plug with wet hands as this may cause electric shocks.
•
Do not use in locations subject to high humidity or dust levels exceeding IP certification, as this may cause
damage to the equipment or start a fire.
•
Do not do anything that may damage the power cable. When disconnecting the power cable, pull on the
plug body, not the cable.
•
Do not damage a power cable, make any modifications to it, place heavy objects on top of it, heat it, place
it near any hot objects, twist it, bend it excessively, or pull it. To do so may cause fire and electric shock.
The whole power cord should be discarded if the cable is damaged in any way.
•
The power cord shall also be discarded if the plug is damaged.
•
Do not place heavy objects on top of the
DPU
.
•
Securely insert the power supply plug as far as it will go.
•
Unplug all cables connected to the
DPU
before moving it.
It is recommended to unplug the power cord from the wall outlet if the
DPU
is not going to be used for any
prolonged length of time.
Never have management port connected while using management VLAN!
3.2
Coaxial Network Requirements
Please consider the following during the installation of the
DPU
.
The risk of potential differences and the spread of voltage from faulty equipment is largely linked to the design
of the power installation in the building. If the coax connections are not galvanically separated according to the
standard EN 60728
{d}
then a galvanic separator, shall be used between the coax connection and the
DPU
.
In terms of potential equalization, the EN 50083-1
{e}
and EN 60728 shall be followed. Cable distribution
systems shall be designed and constructed so that no dangerous voltages can occur in the external conductors
of any cables or in metal cases on passive parts.
3.3
Warning
If the
DPU
is installed in an environment where the surrounding temperature is 70
o
C (158
o
F) or more,
the coax connectors can reach a temperature of more than 85
o
C (185
o
F). In this case the coax connectors
must not be covered or in contact with combustible materials due to the risk of fire.
