Fig. 19
Cage clamp terminals. Use 0.5 to 2.5 mm2 (AWG 20 to 12)
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:
Local requirements demand an individual fuse in each
source line
Neutral and earth impedance is high or undefined
Phase and neutral of the mains are not defined or cannot be
assigned to the corresponding terminals (L
to phase and
N
to neutral).
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.
Caution:
Installation must strictly follow the national safety regulations.
Do not open this apparatus!
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
by TV 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 were further approved by UL according to
UL 60950 (models without E: UL1950), CAN/CSA C22.2 No.
950-95 as UL508-listed components.
Safety approvals for EW models are in process.
The converters have been designed in accordance with said
standards for:
Class I equipment
Power-supply for building-in, vertical mounting on 35 mm
DIN-rail or on a wall
Overvoltage category II (III for 110 VAC supply)
Basic insulation between input and case, based on
250 VAC
Double or reinforced insulation between input and output,
based on 250 VAC and 350 VDC.
Functional insulation between outputs and case.
Functional insulation between outputs.
Pollution degree 3 environment (AC-input) and degree 2
(DC input).
CB Scheme is available (SE-34392).
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO9001:2000.
For details see the Declaration of Conformity (last pages).
Railway Applications
All 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.
