1.4. Before starting the test run
Caution:
•
Turn on the main power switch of the outdoor unit more than 12 hours
before starting operation. Starting operation immediately after turning on
the power switch can severely damage the internal parts. Keep the main
power switch turned on during the operation period.
•
Before starting operation, check that all protective parts are correctly in-
stalled. Make sure not to get injured by touching high voltage parts.
•
Do not touch any switch with wet hands. There may be a risk of electric
shock.
•
After stopping operation, wait at least 5 minutes before turning off the
main power. Otherwise, it may cause breakdown.
2.2. Choosing the interface unit installation location
• Do not install the interface unit in outdoor location as it is designed for indoor
installation only. (The interface board and casing are not waterproof.)
•
Avoid locations where the unit is exposed to direct sunlight or other sources of
heat.
•
Select a location where easy wiring access to the power source is available.
•
Avoid locations where combustible gases may leak, be produced,
fl
ow, or accu-
mulate.
•
Select a level location that can bear the weight and vibration of the unit.
•
Avoid locations where the unit is exposed to oil, steam, or sulfuric gas.
