NOTICE
MOTOR THERMISTOR SENSOR MONITORING
Units with the VLT® PTC Thermistor Card MCB 112 option are PTB-certified for potentially explosive atmospheres.
4.5 Installation Requirements
NOTICE
OVERHEATING
Improper mounting can result in overheating and reduced performance.
-
Install the drive according to the installation and cooling requirements.
•
Locate the unit as near to the motor as possible. See
for the maximum motor cable length.
•
Ensure unit stability by mounting the unit to a solid surface.
•
Enclosures E3h and E4h can be mounted:
-
Vertically on the back plate of the panel (the typical installation).
-
Vertically upside down on the back plate of the panel. Consult the factory.
-
Horizontally on its back, mounted on the back plate of the panel. Consult the factory.
-
Horizontally on its side, mounted on floor of the panel. Consult the factory.
•
Ensure that the strength of the mounting location supports the unit weight.
•
Ensure that there is enough space around the unit for proper cooling. Refer to
.
•
Ensure enough access to open the door.
•
Ensure cable entry from the bottom.
4.6 Cooling Requirements
NOTICE
OVERHEATING
Improper mounting can result in overheating and reduced performance.
-
Install the drive following the installation and cooling requirements.
•
Ensure that top and bottom clearance for air cooling is provided. Clearance requirement: 225 mm (9 in).
•
Provide sufficient airflow flow rate. See
•
Consider derating for temperatures starting between 45 °C (113 °F) and 55 °C (131 °F) and elevation 1000 m (3300 ft) above sea
level. For more information, see the product-specific design guide.
The drive utilizes a back-channel cooling concept that removes heat sink cooling air. The heat sink cooling air carries approximately
90% of the heat out of the back channel of the drive. Redirect the back-channel air from the panel or the room by using either:
•
Duct cooling.
•
Back-wall cooling.
