Section 2: Installation of the Crane Commander.
2.1
Location
Proper location of the inverter is imperative to achieve specified performance & normal
operation life expectancy. The inverter should always be installed in areas where the following
conditions exist:
Within ambient operating temperature range:
Enclosed type:-10° to 40°C (14° to 104°F)
Open chassis type: -10° to 50°C (14° to 122°F)
Rating of enclosure: CC- 204, 207, 215, 222 all rated at NEMA1/IP20. CC-207, 215, 222, 237, CC-
407, 415, 422, 437 all rated protected chassis IP00. CC 255-2220, 455-4220 all are NEMA1/IP20.
Protected from rain and moisture.
Shielded from direct sunlight.
Free from metallic particles and corrosive gas.
Free from excessive vibration. (Below 0.5G)
NOTE: Inverter life expectancy will be shortened if these points are not followed.
2.2
Clearances
For cooling and maintenance purpose, sufficient clearance (as shown in figure 2.2) around inverter
is necessary to keep effective ventilation. Inverter must be installed with heat sink fins oriented
vertically.
