Watlow MICRODIN - Manual (Page 2)

Purpose
To meet Mark CE requirements, this addendum provides supplemental information to the
MicroDIN User’s Manual (W0UD-XUMN Rev A), and the
MicroDIN Quick Start Guide (W0UD-XQRN Rev A).
Power Supply Rating
MicroDIN CE Mark compliance requires an IEC 742 rated power supply. This applies to
the following power supply references:
User’s Manual: p. 3.2, 3.7 (fig. 3.7e), 3.10 (fig. 3.10), 3.11 (fig. 3.11) and A.14
Quick Start Guide: p. 13 (fig. 3.4e), 16, 17 and 22
External DC Output Fusing
Also, a customer supplied 1A fuse is required for external dc output connection to meet CE
compliance. This applies to the following external dc output references:
User’s Manual: p. 3.7 (fig. 3.7b)
Quick Start Guide: p. 13 (fig. 13b)
External DC Output Derating
For MicroDIN CE Mark compliance, external load switching (maximum) for an open
collector is derated from 60V @ 1A to 42V @ 1A. This applies to the following output rating
references:
User’s Manual: p. 3.7 (fig. 3.7b) and A.14
Quick Start Guide: p. 13 (fig. 13b) and 22
