MODELS: Logical character search strings using AND/OR/NOT operators with "asterisk" and "question mark" wildcards, or list ALL models explicitly.
Priority 1: Immediate and unconditional; current production halted until new parts or procedures available. All finished units retrofitted.
Priority 2: All units in production (i.e. all unfinished units) will use new parts or procedures as soon as they become available.
Priority 3: New parts or procedures will be used as soon as they become available AND as soon as existing parts are depleted or declared dead stock.
Priority 4: Alternate parts MAY be used as demand requires.
SAFETY STANDARDS EVALUATIONS: All changes must be assessed to determine their possible impact on Safety Standards approvals and the need to either resubmit
specific documentation, or the entire unit, for updated certification. If it is determined that Safety Standards approvals may be affected, then a Safety Standards Approval
Report must be attached to this ECO detailing steps taken to update necessary approvals.

ENGINEERING CHANGE ORDER #735
MODELS
AFFECTED:
PP300*
SUBJECT:
COMPONENT CHANGES on AFSS-R12 (AC filter & Soft-Start
board)
Revised shield IN-AFSS10-R12
DETAILED DESCRIPTION of, and REASONS for, CHANGE
Diode DZ404, currently a 1N4733 (5V1/1W), can be replaced with 1N5231
(5V1/500mW) on the AFSS-R12 board if its leads are too large for the present holes.
Future revisions of this board will feature larger holes to accommodate the 1N4733’s
heavier leads.
The IN-AFSS-10 insulator shield, installed behind AFSS-r12 board, is replaced with the
IN-AFSS-12 and is now made from Formex GK17 polypropylene to meet safety
standards requirements.
Updated model BOM is PP300-M2
