•
Use a 600V vinyl insulated cable or equivalent to wire the
power supply.
•
To prevent controller damage and failure, supply the
controller with a correctly rated power voltage.
•
To prevent electric shock and controller failure, do not
turn on the power until all of the wiring is complete.
•
To prevent electric shock or controller fire before turning
on the power, verify that the correct distances are kept.
•
Do not touch active electrified terminals. Doing so may
result in electric shock or malfunction.
•
Do not disassemble, fabricate, modify, or repair the
controller. Doing so may result in abnormal operations,
electric shock, or fire.
Maintenance
•
Turn the power off before disconnecting the controller.
Failure to do so may result in electric shock, malfunction,
or damage to the controller.
•
Regular maintenance is recommended to ensure long
life-span and safe usage of the controller.
•
Some parts on the controller have a limited life-span or
may deteriorate with time.
•
The controller and accessories come with a one year
warranty, providing that the product is used correctly.
Caution
Cautions for Installation
Avoid installing the controller in the following locations:
•
Locations where temperatures may fall below 0°C or
exceed 50°C while the controller is in use
•
Locations where humidity may fall below 45% RH or
exceed 85% RH while the controller is in use.
•
Locations where the temperature may suddenly change,
causing condensation
•
Locations that produce combustible or corrosive gases
(esp. sulfide and ammonia gases)
•
Locations where the controller is subject to direct
vibration or shock
•
Locations exposed to water, oil, chemicals, steam, or vapor
(If the unit becomes soaked in water, have it inspected by
the dealer to prevent short circuits or fire.)
•
Locations with a great deal of dust, salt, or iron particles in the air
•
Locations where the controller is subject to interference
from static electricity, magnetism, or noise
•
Locations where the controller is exposed to direct sunlight
•
Locations where heat may accumulate due to radiation heat
Cautions when Attaching the Panels
•
For model PXG4, insert the unit through the back of the
included mounting frame, and push on the frame until the
unit is securely fixed in the panel. If there is still slight
movement in the unit, gently tighten the two screws until
the movement vanishes. (Take care when tightening, as
tightening the screws too much may cause the mounting
frame to separate from the stopper.)
•
The front side of the controller conforms to NEMA-4X
(equivalent to IP 66) for waterproofing. To ensure that
water does not enter between the controller and the panel,
attach the provided packing in the following manner.
(Improper attachment will fail to waterproof the area.)
(1) As shown in figure 1, insert the panel only after
attaching packing to the controller case.
(2) As shown in figure 2, fasten with a mounting frame or
mounting screws to ensure that there is no gap
between the front of the controller and the panel At
this time, check that there are no gaps or warping of
the packing as seen in figure 3.
•
If the panel strength is weak, it may cause a gap to form
between the packing and panel, thus failing to waterproof
the area.
Caution
• Do not block the controller, or the radiation effect will be
lessoned.
• Do not block the ventilating ducts above the terminals.
• When using PXG9, place the mounting brackets into the
mounting hole in the center of the controller.
