Electrical installation warnings and cautions
WARNING
Carry out wiring work only after the frequency inverter
has been correctly mounted and secured.
WARNING
Electric shock hazard—risk of injuries!
Carry out wiring work only if the unit is de-energized.
CAUTION
Debounced inputs may not be used in the safety
circuit diagram.
Fire hazard!
Only use cables, protective switches, and contactors that
feature the indicated permissible nominal current value.
CAUTION
Debounced inputs may not be used in the safety
circuit diagram.
According to product standard IEC/EN 61800-5-1, an
additional equipment grounding (PE) conductor of the same
cross-sectional area as the original protective earthing
conductor must be connected, or the cross-section of
the equipment grounding conductor must be at least
10 mm
2
Cu.
WARNING
The components in the drive’s power section remain
energized after the supply voltage has been switched
off. After disconnecting the supply, wait at least
five minutes before removing the cover to allow the
intermediate circuit capacitors to discharge.
Pay attention to hazard warnings!
Standard mounting instructions
•
Select the mounting location based on requirements
listed in this chapter.
•
Mounting surface must be a flat, non flammable surface.
Mounting orientation can be vertical, horizontal or inclined
(refer to mounting orientation illustration
Figure 7
).
DIN rail mounting is only applicable for vertical mounting,
while screw mounting is applicable for vertical mounting,
horizontal mounting and inclined mounting.
•
PowerXL Series open drives may be mounted side-by-
side or stacked vertically, as outlined in this chapter.
•
Surface must be strong enough to support the drive and
not subject to excessive motion or vibration.
•
Mark the location of the mounting holes on the mounting
surface.
•
Using fasteners appropriate to your VFD and mounting
surface, securely attach the VFD to the mounting surface
using all mounting hole locations.
When mounting one unit above the other, the lower unit air
outlet must be directed away from the inlet air used by the
upper one.
The clearance between the upper and lower unit
should equal C + D. See illustrations above
Table 16.
