2.5 Checking and Controlling the Installation Site
Install the VS-616G5 in the installation site described below and maintain optimum conditions.
2.5.1 Installation Site
Install the Inverter Panel under the following conditions.
D
Install the Inverter Panel at an altitude of 1,000 m or less.
D
Install the Inverter Panel in a location with an ambient temperature ranging from --5 to 40 °C.
•
Do not expose the Inverter Panel to hot air currents.
•
Install the Inverter Panel in a well-ventilated location. If the Inverter Panel is located in a poorly
ventilated location, ambient temperature will rise due to the Inverter panel or other heat sources.
D
Install the Inverter Panel in a location free from harmful gasses or sea wind that may cause rust or corro-
sion.
D
Install the Inverter Panel in a location free from dripping water or condensation.
Observe the following precautions when installing the Inverter Panel indoors.
•
The building roof made of metal or glass may cause water condensation to drip on the Inverter Panel.
•
Water leakage from water pipes may drip on the Inverter Panel.
•
When installing the Inverter Panel in a concrete room, particularly in building underground, where
concrete tends to keep moisture, the Inverter Panel may be affected by moisture. In such case, pro-
vide a space heater inside the Inverter Panel to constantly keep the in-panel temperature higher than
the ambient temperature.
D
Install the Inverter Panel in a clean location free from dust. Otherwise, contacts may malfunction or in-
sulation destruction may occur.
D
Install the Inverter Panel in a location free from excessive vibration or shock.
D
Install the Inverter Panel in a location free from explosive or combustible gases.
D
Install the Inverter Panel in a location where openings are provided for cleaning, inspection, and mainte-
nance. (The Fire Protection Law specifies minimum openings in the front and back sides of the Inverter
Panel.)
2.5.2 Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter Panel should be installed in an environment free from
extreme temperature increases. If the Inverter Panel is installed in an enclosed environment, such as a box,
use a cooling fan or air conditioner to maintain the internal air temperature below 40°C.
2.5.3 Protecting the Inverter Panel from Foreign Matter
Place a cover over the Inverter Panel during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter Panel after completing installation. Otherwise, ventilation will
be reduced, causing the Inverter Panel to overheat.
2.5.4 Floor Level
The floor where the Inverter Panel is installed must be level to within ±3 mm per square meter.
2.5.5 Inverter Panel Connections (Side-by-side Connection)
When connecting more than one Inverter Panel in a series, use connection bolts.
Tighten the four bolts along both the front side and back side. Tighten them carefully so that the front sur-
faces of each Inverter Panels are aligned with each other and so that all the connected Inverter Panels remain
stable.
