Chapter 3 Mechanical Installation
3.1 Installation Precautions
• Do not install if the inverter is imcomplete or impaired.
• Make sure that the inverter is far from the explosive and flammability things.
• Do not operate the inverter until the power is cut-off 10 minutes later.
• It is required not only carry the display panel and the cover but also the inverter bottom enclosure.
• Do not play metal into the inverter when installing.
3.2 Requirement for the Installation Site
Ensure the installation site meeting the following requirements:
•
Do not install at the direct sunlight, moisture, water droplet location;
•
Do not install at the flammability, explosive, corrosive gas and liquid location;
•
Do not install at the oily dust, fiber and metal powder location;
•
Be vertical installation on fire-retardant material with a strong support;
•
Make sure adequate cooling space for the inverter so as to keep the ambient temperature
between - 10
－
+ 40
℃
;
•
Install at where the vibration is less than 5.9m/s
2
(0.6g).
Note:
1. It needs derating use if the inverter operation temperature exceeds 40
℃
. The derating value of
the output current of the inverter shall be 2% for each degree centigrade. Max. allowed
temperature is 50
℃
.
2. Keep ambient temperature between -10
－
+40
℃
. It can improve the inverter operation
performance if install at the location with good ventilation or cooling devices.
3.3 Installation Direction and Space Requirements
To achieve good cooling efficiency, install the inverter perpendicularly and always provide the
following space to allow normal heat dissipation.
HD20 series inverters can be mounted in parallel, shown in Figure 3-1.
