5.4.2 Shielding against Electrical Noise
Before mounting the line power cable, mount the EMC metal cover to ensure best EMC performance.
NOTE: The EMC metal cover is only included in units with an RFI filter.
Figure 5.36: Mount the EMC shield.
5.4.3 External Fan Supply
If the adjustable frequency drive is supplied by DC or if the fan must run independently of the power supply, an external power supply can be applied.
The connection is made on the power card.
Terminal No.
Function
100, 101
102, 103
Auxiliary supply S, T
Internal supply S, T
The connector located on the power card provides the AC line voltage connection for the cooling fans. The fans are factory-equipped to be supplied from
a common AC line (jumpers between 100-102 and 101-103). If an external supply is needed, the jumpers are removed and the supply is connected to
terminals 100 and 101. A 5 Amp fuse should be used for protection. In UL applications, this should be a LittleFuse KLK-5 or equivalent.
