Precautions for Correct Use
(1) Observe the following precautions when installing and storing the product.
a) Protect the wiring by, for example, placing it inside wiring ducts if there is a possibility that it may be damaged by animals or other
factors.
b) Protect the product from falling snow, accumulated snow, or wind-blown snow by building a protective roof over it when installing
the product in a snowy region.
c) Provide sufficient safety measures, such as scaffolding, to prevent danger during installation work.
d) Store in a place where the temperature is within the range of
−
25 to 60
°
C (with no condensation or icing), and the humidity is 95 %
maximum.
e) Store in a place that is no more than 2,000 m above sea level.
(2) Do not use this product in the following places:
a) Places subject to intense temperature change.
b) Places subject to volatile, flammable, corrosive, or other toxic gas.
c) Places subject to vibration and large shocks.
d) Places subject to water vapor, oil vapor, or condensation.
e) Places where the main body may be immersed in water.
f) Places subject to electric fields, direct sunlight, poor ventilation(ex. Narrow places where the ventilation would be obstructed or the
ambient temperature conditions would be exceeded.), considerable dust, many small insects.
g) Places subject to temperature and humidity conditions outside of the following ranges.
· Temperature:
−
20 to 55
°
C
· Humidity: 4 to 100 %
h) Places more than 2,000 m above sea level.
i) Narrow places where the ventilation would be obstructed or the ambient temperature conditions would be exceeded.
(3) Omron KP100G PV Inverter shall be installed and used properly in a way to keep away from the following incidents
a) altered or repaired, maintained or overhauled except by OMRON or any person expressly authorized by OMRON, without prior
written consent of OMRON
b) use of parts or accessory other than OMRON specify
c) defect caused by circumstantial factors such as wiring or peripheral equipment to be connected
d) pro-longed mechanical stress; eg. Tiny but continuous vibration for a long period
(4) Omron KP100G PV inverter shall be installed and used properly in a way to prevent the following possible incidents;
a) Lightening surge; easier to penetrate into a PV inverter by conducting on lines between PV modules and PV inverters comparing to
other apparatus installed in the house like a washing machine and may result in a breakage of PV inverter
b) Surge noise (spike) caused by a nearby construction work; flow into a PV inverter and may result in a breakage
c) Grid instability caused by a nearby construction work; make voltage variation larger and cause a malfunction, it may result in a
claim to replace the product
d) Nearby plant (under a poor grid connection); make voltage and/ or frequency vary too largely to activate an error (message), as it
happens repeatedly the customer starts suspecting the quality or defect of the product and it may result in a claim to replace the
product
e) Home apparatus without grounding (eg. washing machine); make a noise to a PV inverter from time to time and it may result in a
breakage
f) Installation circumstances that cause internal relays of PV inverter to repeat switching on and off; it may result in a welded contact
before its life time. It should be a set up that is good at making a balance of startup and stop of PV modules.
g) Characteristics matching with PV modules (as a PV system); amorphous PV modules cause leakage current detector to be
erroneously activated when it is set up, in rain, or as time goes by, and shut down a PV inverter, and it may result in a claim to
replace the product.
