VG5 Installation & Quick-Start Manual 19
Clearances
When mounting the VG5, allow sufficient clearances for effective cooling as shown below:
Notes:
1) The required clearances at the top, bottom, and both sides of the inverter are the same for both open chassis and NEMA 1
enclosures.
2) For inverter models 25HP and less (230V & 460V), and models 20HP and less (575V), remove the top and bottom covers
to convert NEMA 1 units to open chassis.
3) Allowable intake air temperature:
Open chassis: 14°F to 113°F (-10°C to +45°C)
NEMA 1: 14°F to 104°F (-10°C to 40°C)
4) When mounting units in an enclosure, install a fan or other cooling device to limit the air temperature within the inverter
to below 113°F (45°C).
