TE Connectivity Sense KFM-2401 Series Installation Manual

Installation
1- Always allow good ventilation clearances, 5mm left and right, 40mm above and 20mm below, around the unit in use to
prevent it from overheating.
2 - The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on the top.
Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not allowed.
3 - Use copper wire only, and recommended wires are shown as below
AWG
Rated Current of
Equipment (Amp)
Cross-section of
Lead(mm2 )
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.
