Notes:
1. Load regulation is specified for a load change of Input Connection Mounting and Airflow
20% to 100%.
2. Overload protection is current limiting. The unit
recovers automatically when the fault is removed.
3. Over voltage protection is a shut down type. The
unit recovers automatically when the fault is
removed.
4. The MDR-24 meets class 1 safety require-
ments with a proper PE connection. To insure
compliance to EN 60950, it must be possible to
switch off the unit using suitable disconnection
device external to the power supply.
5. It is recommended that a fuse be used on the
input of a power supply for protection. For the
MDR-24 series, a 250 VAC 3.15A is recom-
mended.

The MDR-24 series may be connected to single or To allow proper ventilation, the MDR-24 series should be mounted so they are
8 AC/Line (L+) three-phase AC networks as shown. All wires should vertically orientated with approximately 2 inches (50 mm) of clearance above and
be 14-25 AWG. For safety, all wires should be stripped below the unit. No minimum spacing is required between units. Ventilation holes
approximately 7 mm. and any connections to the supply should not be covered and proper derating should be followed.
should only be made with the system power off. Do not
operate without a proper PE connection.
Mechanical Dimensions Installation/Removal
Install
To mount the unit to the
DIN rail, tilt the unit rear-
wards from the top, fitting
the mount over the top of
the rail. Press back on the
bottom front of the unit until
it locks in place on the rail.
Remove
To remove the unit from the
rail, pull the removal clip at
the bottom rear of the unit
downward with a screw
driver. With the clip down,
lift up on the unit from the
bottom front until it clears
the rail.
Before installation or re-
moval all wiring should be
disconnected and the main
power to the system shut off.
