Standards and Approvals
The converters are approved by UL and TV according to UL
60950, CAN/CSA C22.2 No. 950-95 and IEC/EN 60950-1:2000.
The converters have been evaluated for:
Building in
Basic insulation input to output, based on their maximum
input voltage
Pollution degree 2 environment
Connecting the input to a secondary circuit, which is subject
to a maximum transient rating of 1500 V for 20IMX4 and
40IMX4, 2000 V for 70IMX4 models.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards.

Railway Applications
To comply with railway standards, all components are coated
with a protective lacquer (except option Z).
Protection Degree
The protection degree of the converters is IP 30, except open-
frame models (option Z).
Cleaning Agents
In order to avoid possible damage, any penetration of cleaning
fluids should be prevented, since the power supplies are not
hermetical sealed.
However, the open-frame models (option Z) leave the factory
unlacquered and may be cleaned and lacquered by the
customer, for instance together with the mother board. Consult
Power-One for suitable cleaning agents.
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 honour
any guarantee claims resulting from electric strength field tests.
Description of Options
Option K: Alternative Pinout.
This pinout is compatible with other converters on the market,
for instance with the IPS3 series.
Option Z: Open Frame
For applications, where the protection of the case is not neces-
sary or in the case that the motherboard should be cleaned and
lacquered with the converter fitted.
To prevent excessive current flowing through the input lines in
case of a short-circuit, an external fuse specified in table 6 should
be installed in the non-earthed input supply line.
Pin Allocation
NUCLEAR AND MEDICAL APPLICATIONS - Power-One products are not designed, intended for use in, or authorized for use as critical
components in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written
consent of the respective divisional president of Power-One, Inc.
TECHNICAL REVISIONS - The appearance of products, including safety agency certifications pictured on labels, may change depending
on the date manufactured. Specifications are subject to change without notice.
