panels and to the base frame. Avoid any part of the machine falling during unloading and/or moving, as this could cause
serious damage.
All units of the series are supplied with four lifting points. Only use these points for lifting the unit, as shown in Fig. 15.
Fig. 15 - Lifting the VFD
WARNING
– Both the lifting ropes and the spacing bar and/or scales must be of sufficient size to
support the machine safely. Please verify the unit
’s weight on the machine’s nameplate.
The weights shown in the
“Technical data” tables refer to standard units.
The machine must be lifted with the utmost attention and care. Avoid jolting when lifting and lift
machine very slowly, keeping it perfectly level.
14.7.3 Positioning and assembly
All units are produced for indoor installation. Outdoor installation should be avoided although the cabinet is IP54 rated. Th e
cabinet must be installed vertically on a robust and perfectly level foundation.
To avoid heat sink overheat and/or damage on the installation site, the following precautions and instructions must be
followed:
−
Avoid air flow recirculation.
−
Make sure that there are no obstacles to hamper air flow.
−
Air must circulate freely to ensure proper intake and expulsion.
14.7.4 Minimum space requirements
It is fundamental to respect minimum distances on all units, in order to ensure optimum ventilation for the electrical panel
and to allow easy maintenance. All cabinets have ventilation fans placed in the front door (horizontal air flow) for to keep
the electrical panel cold. The air passages must remain absolutely free of ostructions to ensure maximum cooling efficiency.
Air filters must be periodically checked and cleaned.
A minimum space on front of the panel must be left in order to allow easy maintenance and repair of cooling fans. Fig. 16
shows the minimum space required.
Should the machine be installed without observing the recommended minimum distances from walls and/or vertical
obstacles, there could be a combination of warm air recirculation and/or insufficient supply to the inverter air -cooled
heatsink which could overheat the VFD.
