8.3. Connection and Installation
This section describes basic installation for the PSU.
8.3.1. Setting
When installing the PSU, the following guidelines should be complied:
Check factors such as accessibility, power, signal, and cable connections and future expansion on
the installation location.
Plan for access to connector side of the PSU.
Ensure the location where the PSU operates has adequate ventilation around the fan intake and
exhaust. Ambient air temperature may not cool the PSU to acceptable operating temperatures
without adequate ventilation.
Arrange the PSU with the install direction and space in below
Available to use the mount bracket for Φ76 mast as option parts.
Install Direction and Space
The install direction and space in accordance with following are recommended to secure and to
keep the heat dispassion performance.
i) Install Direction
a) In case of “Horizontal Direction”
Cooling fan side shall be set to upward direction in below.

ii) Space
More than 30mm of space at least from inlet/outlet of cooling fan must be reserved.
Do not block airflow of this unit fan to keep the heat dispassion performance.
The install direction and space mentioned are recommended to secure.
8.3.2. Connection
Two cables and one wire:
AC Power Cable
DC Power Cable between the PSU and BUC
Wire for Common Chassis Ground / Frame Ground
1) AC Power Cable
The PSU is directly powered by AC power source (100-240V). Low noise / low transient AC power
source is recommended.
The connection of AC power cable should be complied with the following steps:
Step 1: Assemble the AC power cable. Use a power cable with an outer diameter (O.D.) of 9 -
13 mm to properly assemble the mating connector (Model: GTS06CF-16-10S(025))
included in the shipment package. The connector pin assignment should be referred in
Item (d) of Section 8.2.2. The assembly method of mating connector is referred to

appendix. The appropriate three-plug terminal should be selected according to the
outlet shape to be used, and assembled to the power cable at the opposite side of the
mating connector.
It is available to purchase the AC power cable of P/N: NJZ1290A03 as option part.
Step 2: Connect the mating connector (Model: GTS06CF-16-10S(025)) of the AC power cable
to the connector of AC Input of the PSU correctly and securely. And for to harden the
waterproof structure it is recommended that a cable connection point from the
connector to the cable sheath is sealed by usage of self-amalgamating tape.
Do not connect the AC power cable to the AC outlet before all of other connection steps.
2) DC Power Cable between the PSU and BUC
The PSU supplies +51V DC power to BUC though this connection cable.
The connection of the DC power cable between the PSU and BUC should be complied with the
following steps:
Step 1: Assemble the DC power cable. Use a power cable with an outer diameter (O.D.) of
10.9 mm. The cable length should refer to Section 8.3.4, and for the decision of cable
length it is needed to consider the voltage drop due to the conductor resistance of the
wires. Properly assemble the mating connector (Model: PT06E-12-3S(470)) included in
the shipment package of the PSU to the power cable. Properly assemble the mating
connector (Model: PT06E-12-3S(470)) included in the shipment package of the BUC to
opposite side of the aforementioned power cable. The pin assignment of connectors
should be referred in Item (a) and (c) of Section 8.2. The assembly method of mating
connector is referred to appendix.
It is available to purchase the DC power cable of P/N: NJZ1290A04 as option part.
Step 2: Connect the appropriate mating connector (Model: PT06E-12-3S(470)) of the DC
power cable to the connector of DC Output at the PSU correctly and se c u re l y. And for to
harden the waterproof structure it is recommended that a cable connection point from
the connector to the cable sheath is sealed by usage of self-amalgamating tape.
Step 3: Connect the appropriate mating connector (Model: PT06E-12-3S(470)) of the DC
power cable to the connector of DC Input at the BUC correctly and securely. And for to

harden the waterproof structure it is recommended that a cable connection point from
the connector to the cable sheath is sealed by usage of self-amalgamating tape.
3) Wire for Common Chassis Ground / Frame Ground
The PSU can be had the chassis ground of the other equipment (e.g. modem) in common.
Connecting wire for common chassis ground from the chassis ground of the other equipment
should be complied with the following step:
Tools Required: #2 Phillips screwdriver
Step: Connect the wire from ground on the other equipment to the ground hole with M4 x 8
mm Philips pan head screw.
DC power of +51 V will output at DC output interface connector. Do not connect the other than
cable connected from the +51V operable BUC. The connected equipment may be damaged
when cable connecting modem, the BUC other than the +51V operable BUC
, or other
equipment.
Do not connect the AC power cable to the AC outlet before all of other connection steps.
To reduce the risk of damage or broken by lightning surge, the unit should be
grounded by
connecting the ground wire.

Do operate with the input voltage range between +100 and +240 V AC power. Avoid applying
more than the maximum voltage in this range under any conditions.
Do seal all of cable connection points from the connector to the cable sheath by
usage of
self-amalgamating tape for to harden the waterproof structure
8.3.3. Start-up
Start-up will be immediately performed with the following step:
Step: Connect the AC power cable to the AC outlet
8.3.4. Recommendation Cable between PSU to BUC
Type and length of the signal cable from the PSU to BUC need to be chosen to satisfy that the PSU
output less than 500 W DC power, and an input voltage of BUC is more than input minimum voltage
such as 36 V.

8.4. Maintenance
This section describes basic maintenance for the PSU.
8.4.1. Dust Removal
Regular dusting / dust removal will ensure the PSU to operate within operational specification.
Use a slightly damp cloth with excess moisture wringed out (not saturated, wet or dripping cloth)
to wipe away the dust that collects on the outside of the enclosure
A high, dusty environment will require frequent maintenance of vacuuming the dust off the
enclosure vents and circuit board.
8.4.2. Fan Field Replacement
The PSU requires to flow forced-air by the installed fan on rear panel for cooling.
It is recommended that the fan is to be replaced with a new one at five years interval.
The fan has its lifetime. The fan is to be replaced with a new one at appropriate interval. The
recommendation interval of replacement is 5 years.
