Cage clamp terminals. Use 0.5 to 2.5 mm 2 (AWG 20 to 12)

solid or stranded wires depending on local requirements.

The phase input (L) is internally fused; see Input Fuse and

Protection. 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 converter operates at source voltages above 250 VDC,

an external DC fuse or a circuit breaker at system level should

be installed in the phase input line L .

Caution:

• Installation must strictly follow the national safety regulations.

• Do not open this apparatus!

Protection Degree and Cleaning Agents

The protection degree of the converters is IP 20. Protective

covers over input and output terminals are available on

request; see Accessories.

Any penetration of liquid or foreign solid objects has to be

prevented, since the converters are not hermetically sealed.

Standards and Approvals

The X Series converters were approved according to IEC/

EN 50178, IEC 61010-1, IEC60950-1, UL/CSA 60950-1 2nd Ed.

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-34628).

The converters are subject to manufacturing surveillance in

accordance with the above mentioned UL standards and with

ISO9001:2000.

See also the Declaration of Conformity (last page).

Railway Applications

All X Series converters have been designed by observing the

railway standards EN 50155 and EN 50121. All boards are

coated with a protective lacquer.

Isolation

The electric strength test is performed in the factory as routine

test in accordance with EN 50116 and IEC/EN 60950, and

should not be repeated in the field. Power-One will not honor

any warranty claims resulting from electric strength field tests.
