The Ham required an external filter P/N07818
to meet IEC801-5 Level 3, EN55022 Level A,
AS/N25 2064 class A
AS/NZS CISPR11 Group 1 Class A

NOTE All VI-HAM versions must be preceded by three transorbs in series directly
across the input. Also use 10A 3AG fast blow fuse ahead of line filter.

If power requirements exceed one HAM, use a HAMD and one or more BAMDs, with an external
bridge rectifer. HAM, HAMD, and BAMD modules require three surge suppressors in series directly
across the input. These surge suppressors are already contained in the EMI filter P/N 30205. Also
use a 10A, 3AG fast-blow fuse ahead of the line filter.
* Compatible with V375 series.
