Cage clamp terminals. Use 0.5 to 2.5 mm
solid or stranded wires depending on local requirements.
This fuse is designed to break an overcurrent in case of a
malfunction of the converter and is not customer-accessible.
External fuses in the wiring to one or both input lines (L and/
or N ) may be necessary to ensure compliance with local
requirements. A built-in second fuse in the neutral path is
available as option F.
A second fuse in the wiring to the neutral terminal N or option
F is needed if:
Models with Option F: Caution! Double-pole/neutral fusing.
If the converters operate at source voltages above 250 VDC,
an external fuse or a circuit breaker at system level should be
installed.
Protection Degree
The protection degree of the converters is IP 20. Protective
covers over input and output terminals are available on
request; see Accessories.
Cleaning Agents
Any penetration of liquid or foreign solid objects is to be
prevented, since the converters are not hermetically sealed.

Standards and Approvals
The converters of the LW Series with feature E were approved
according to IEC/EN 60950-1:2001 (IEC/EN 60950 for models
without E), IEC 61010-1:C11:2002 (models without E: IEC
61010-1), and EN 50178:1997 (with and without E).
The converters are UL508-listed and approved according to
UL 60950-1 and CAN/CSA C22.2 No. 60950-1.
Safety approvals for EW models are in process.
The converters have been designed in accordance with said
standards for:
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO9001:2000.
Railway Applications
The W Series converters have been designed observing the
railway standards EN 50155 and EN 50121. All boards are
coated with a protective lacquer.
The EW Series is particularily suitable for connection to 110 V
railway batteries.
