Notes:
1. Load regulation is specified for a load
change of 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
requirements with a proper PE con-
nection. To insure compliance to
EN60950, it must be possible to switch
off the unit using suitable disconnec-
tion 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 recommended.

The
MDR-24
series may be connected to single
or three-phase AC networks as shown. All wires
should be 14-25 AWG. For safety, all wires
should be stripped approximately 7 mm. and
any connections to the supply should only be
made with the system power off. Do not oper-
ate without a proper PE connection.
To allow proper ventilation, the
MDR-24
series should be mounted
so they are vertically orientated with approximately 2 inches (50
mm) of clearance above and below the unit. No minimum spacing
is required between units. Ventilation holes should not be covered
and proper derating should be followed.
Mechanical Dimensions
Installation/Removal
Install
To mount the unit to
the DIN rail, tilt the unit
rearwards 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 removal all wiring
should be disconnected
and the main power to
the system shut off.
