Pay attention to the followings to prevent any personal injury caused by an
electric shock when using an insulation tester.
- Make sure the polarity is correct when connecting the Earth COM (black) and
AC.V (red) lead lines. And do not touch the connected probes inspecting part of
the lead line) with a hand and avoid body contact.
- Avoid body contact to the system when measuring an insulation resistance.
Watches, rings, and other metallic accessories
Do not wear accessories such as watches and rings in order to prevent electrical
short-circuit.
Power Switch Off
Make sure the power switch of power supplier is off when installing the system.
Installing the system with power switch on may cause system damage or fatal
human injury when cables are not correctly connected.
Connecting Ground Cable
When connecting the cables, always connect the ground cable first. If worker
contacts the equipment, connect a cable or perform maintenance without
connecting the ground cable, the system can be damaged or a worker may be
injured due to static electricity and short circuit.
Turning Off the Circuit Breaker before Connecting the Power Cable
Since power is applied to the system where the power cable is connected by
manipulating the circuit breaker of the AC distributor, be sure to check the AC
distributor’s breaker and the system switch are turned off (open) before
connecting the power cable to the power connector. If the system is installed
while the circuit breaker and system switch is on, the worker may be critically
injured as soon as the cable is connected in the wrong way.
Make sure that worker wears protection gloves and goggles to prevent damage
from debris while drilling holes in a wall or ceiling.
CAUTION
Power and Feeder line
Cautions while Cleaning Power Supply
While cleaning the power supply device, take caution that the device does not
come in contact with alien bodies that may cause power failure.
Precautions While Measuring Insulation Resistance
Observe the followings to prevent any system damage when measuring insulation
resistance because there is a very high voltage.
- Before measuring insulation resistance, disconnect all the cables connected to
the system.
- Do not measure insulation resistance when power is on.
- Do not measure insulation resistance at any other positions such as system
internal units or parts other than the targeted insulation resistance measuring
points.
Ground bar for lightning protector/power/communication must be isolated from
each other. These three ground bars can be grounded as the isolation grounding
method, or branched from ground mesh buried in the underground as common
grounding method.
Precautions When Connecting Power Cable
To secure rainproof performance of a cable gland, min. 11.81 in. (300 mm)
straight section must be maintained. Here, the radius of curvature must be
considered according to the cable specification.
When Using Power Cables
- When handling the power cable, ensure the power switch of a rectifier is turned
off to prevent the risk from the power cable and electric short-circuit of related
cables.
- Because a power accident may occur when fixing parts get loosened, make
sure that fasteners to fix the power cable should be firmly fastened.
- The resistance temperature of power cable should be higher than 194°F (90°C).
AC Power cable
In case of using AC power cable (AWG 14, F-FR-8 1.5 mm2 × 3C), it is applicable up
to 721.8 ft (220 m). When the distance is 721.8 ft (220 m), followings should be
considered.
- Do not rapid ON/OFF (within one second): The voltage loss value caused by the
cable resistance, and the Outdoor Pico could be damaged by the counter
electromotive force caused by the cable inductance.
- Do not use the power cables linked: Using the power cables linked each other,
the loss will be increased.
- For the length of the AC power cable, follow the safety regulation of the
installation site.
Cautions When Connecting AC Power
When connecting the AC power cable to the L1-GND-L2, check the polarity of
each phase at the L1-GND-L2 single-phase connection area of AC power
distributor to ensure that correct polarity is connected to the L1-GND-L2 of the
system's input end. Check if the 120V-240 V between L1 and L2 is within the
allowable range (with tolerance of +/-10%).
Connecting the feeder cable connector is critical process, so the qualified workers
who finished the related education should perform.
Installing the Antenna
When you install the antenna, the antenna must be within the protective angle
(left/right side 45° each from the central axis) to prevent the antenna from
lightning damage.
Cautions on the Min. Radius of Curvature of GPS Cable and Its Length
Limitation
If the GPS cable min. radius of curvature or its length limitation is violated, a GPS
signal may not be received seamlessly and it may cause abnormal system
operation. Therefore, the min. radius of curvature and length limitation of a GPS
cable proposed in the above table must be observed.
Checking VSWR for Minimum Cable Bend Radius and Length of RF Cable
If the VSWR value for minimum cable bend radius and length of RF cable is not
applied, system may not work properly because RF signals cannot transmit or
receive smoothly. So, the VSWR value for minimum cable bend radius and length
of RF cable must be checked and applied.
Cau t io ns When Measuring VSWR
When measuring VSWR, if you open the antenna port when the transmission
output is not completely off, a spike signal may flow into the reception path, which
may cause damage to LNA. Make sure the transmission output is completely off
when measuring VSWR.
Cautions When Connecting Feeder Lines
If you install the feeder line which is connected to the system, it may damage the
system and cable connection. Therefore, it is recommended to install the feeder line
up to the system's input port before connecting the feeder line to the system.
Be careful not to damage the cables when cleaning the system.
Do not Work by Yourself
Worker must not work alone in any key process.
Finishing the System Input/output Port and Cable Inlet
To prevent foreign substances, outdoor air and moisture from entering the system
input/output port and cable inlet (including cable gland and conduit), finish it as
follows:
- Unused inlet
Use the hole finishing materials including waterproof cap and rubber packing.
- Cable-installed Port and Cable Inlet
After cable installation, block any space in the inlet with tape, compressed
sponge, rubber packing, and silicon.
Checking Marking (horizontal/vertical) When Mounting the System on Wall
If you do the drilling or anchoring on a wall when the positions are not marked to
be horizontal or vertical, only limited range of tuning is allowed for leveling after
the system is mounted.
To mount the system on a wall, perform the leveling test by referring to ‘System
Leveling’ to check the positions are marked to be horizontal or vertical before
drilling. If the result shows they are not horizontal or vertical, modify the marking
positions.
Co nsiderations when Cutting the Cable after Installation
When cutting the cable after installation, make sure that the connector is
disconnected. Installation of the cable with the connector connected to the system
may cause contact failure or damage to the connector assembled to the system
and the cable due to cable tension or the operator’s mistakes.
Cover the unused ports (conduit, cable gland, etc.) with waterproof cap (sealing
cap) to prevent infiltration of foreign material such as dust, moisture, or bug.
Installing the Concrete Block
A concrete block should be installed that satisfies the specification regarding size
and strength. When installing the concrete block, and before forming the
concrete, steel reinforcement bars should be arranged in a mesh layout at
100 mm intervals before forming the concrete. (Either an anchor bolt assembly or
a concrete anchor can be used.)
