Note
:
Current each wire carries should be de-rated to 80% of the current suggested
above when using 5 or more wires connected to the unit.
Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are
securely fixed to prevent poor contact. If the power supply possesses multi-output terminals, please make
sure each contact is connected to wires to prevent too much current stress on a single contact.
(4)Use wires that can withstand temperatures of at least 80°C such as UL1007.
(5)Recommended wire strapping length is 6.5mm (0.255”).
(6)Recommended screwdriver is 3mm, slotted type.
(7)The recommended torque setting for terminals is 5.8 kgf-cm (5.0 Lb-in).
(8)Suggested fuse and maximum number of the MDR PSUs that can be connected to a circuit breaker at 230V are
shown as below.

(4) Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
(5) Only install the unit in a pollution degree 2 environment (Note.1).
(6) Please do not install the unit in places with high moisture or near the water.
(7) The maximum operating temperature is 35°C for MDR-100-12 and 40°C for MDR-100-24, MDR-100-48 and
50°C for MDR-10/20/40/60 series, please do not install the unit in places with high ambient temperature or
near fire source.
(8) The FG ( ) must be connected to PE (Protective Earth).
(9) Output current and output wattage must not exceed the rated values on its specification.
(10)Disconnect system from supply voltage:
Before commencing any installation, maintenance or modification work: Disconnect your system from
supply voltage. Make sure that inadvertent connection in circuit will be impossible!
(11)For continued protection against risk of fire, replace only with same type and rating of fuse.
Pour ne pas compromettre la protection contre les risqué d’incendie, remplacer par un fusible de même
type et de memes caractéristiques nominales.
Note.1: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become
conductive due to occasional condensation. Generally refer to dry, well-ventilated locations, such as
control cabinets.
