Notes :
1. Norminal specs represent the design specs. All unit should be able to approximate these some will
exceed and some may drop slight below these specs. Limit specs represent the absolute worst
condition that still might be considered acceptabie; in no case should a unit fail to meet limit specs.
2. This manual is based on the General European(D) standard, and provieds information on regional
circuit modification through the use of alternate schematic diagrams or wiring diagram, and
information on regional component variations through the use of parts lists. Design and
specifications subject to change without notice.
