Standards and Approvals
All Melcher power supplies are subject to manufacturing
surveillance in accordance with ISO 9001 standards.
All units are UL recognized as per UL 1950, UL 1012 and
CAN/CSA C22.2 No. 234-M90.
Installation Instructions
The connector pin allocation table defines the electrical
potentials and the physical pin position on the connector.
Pin no. 32 is the protective ground pin and is protruding, i.e.
attaching the female connector, this pin provides electrical
contact first. The modules should only be wired via the fe-
male connector H11 (according to DIN 41612) to ensure
requested safety!
Protection Degree
The protection degree is defined by IP 30 (equipped with
any potentiometer adjustable option: IP 20). The protection
degree applies only if the module is plugged-in or the fe-
male connector is properly attached to the module.
