M Series
The M series power entry modules offer the most choices
of power entry components and filtering options to fit a
specific need. The fully configured M series expands the
options of a manufacturer whose products are marketed
worldwide. One component, fully assembled and tested,
provides the capability of interfacing a multi-voltage power
supply to any common voltage or fusing scheme in the
world, without modification.
•The IEC connector provides an internationally accepted
power entry termination, which can be used with a variety
of line cords.
•The selectable fuseholder allows use of single or dual
European fuses, or a single North American fuse.
•The optional DPST on/off switch breaks both sides of the
line and is labeled with the international I/O markings.
•The optional voltage selector provides a convenient
means to change transformer primary connection,
and it is available in both 2-voltage and 4-voltage
configurations.
•The series is available with four filter circuits to meet a
variety of applications, and convenient connections are
provided on unfiltered models to allow wiring of a
separate RFI filter.
The M series is a family of components offering greater
flexibility and cost-effectiveness in the selection of primary
power components. Wiring to the modules is accom-
plished via .110” terminals for labor savings and
convenience.
Four filter circuits provide a choice of attenuation tailored to
specific categories of susceptibility and emissions needs.
HM Models
– This medical filter provides susceptibility
protection without the leakage current associated with
line-to-ground capacitors. Designed to allow equipment
to meet UL544 for patient care and non-patient care
equipment, the HM filter has a maximum leakage current
of 2 µA at 120 VAC 60 Hz. See Appendix C for more
information on medical applications and UL standards.

Dimensions are in inches and
millimeters unless otherwise
specified. Values in italics
are metric equivalents.
FM Models
– General purpose RFI filter designed for sus-
ceptibility applications, effectively providing RFI control of
line-to-ground noise. The design is compact and meets
the very low leakage current requirements of VDE portable
equipment as well as (120 Volt) UL544 non-patient medical
equipment.
XM Models
– High performance RFI filter designed to bring
most digital equipment (including switching power
supplies) into compliance with FCC Part 15J, Class B
conducted emissions limits.
ZM Models
– Premium RFI filter designed to bring most
digital equipment (including switching power supplies) into
compliance with EN55022, Level B (as well as FCC Part
15J, Class B) conducted emissions limits.

2. Once lifted, the door will pivot on it’s hinges and
expose the fuse holder.
**Install fuses on one side only. Do Not install both AG and Metric fuses at
the same time.
Voltage Selection
To change selected voltage: open cover, using small
blade screwdriver or similar tool; set aside cover/fuse
block assembly; pull voltage selector card straight out of
housing, using indicator pin; orient selector card so that
desired voltage is readable at the bottom; orient indicator
pin to point up when desired voltage is readable at bottom
(note that when indicator pin is fixed, successive voltages
are selected by rotating the card 90° clockwise); insert
voltage selector card into housing,
printed side of card
facing forward toward IEC connector and edge containing
the desired voltage first;
replace cover, and verify that
indicator pin shows the desired voltage.

3. When the fuse holder is installed in the single fuse
position, apply the screwdriver as shown and gently
pry up. Use screwdriver as shown, do not use fingers.
When the fuse holder is installed in the dual fuse
position, it will normally release as soon as the
door is opened.
