TECHNICAL DATASHEET
PMT Panel Mount Power Supply
4.2V 252W 1 Phase / PMT-4V350W1A
Assembly & Installation
Side Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
Ⓐ
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 5mm length (Refer to Fig. 4 on the
next page). This is to maintain a safety distance between the screw and internal components.
Base Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
Ⓑ
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 4mm length (Refer to Fig. 4 on the
next page).
Connector
Ⓒ
This surface belongs to customer's end system or panel where the power supply is mounted.
Ⓓ
Base Mounting (Horizontal)
–
Use flexible cable (stranded or solid) of AWG No. 14-12. The input/output connectors' allowable current is 23A max per pin. User
should calculate and select the suitable wire specification (type/quantity/diameter) according to actual output current. The torque at
the connector shall not exceed 13Kgf.cm. The insulation stripping length should not exceed 0.275" or 7mm.
–
Recommended mounting torque of the product and its mounting accessories is 9~12Kgf.cm.

Mounting Hole Locations and the Safety Distance
Ensure the mounted device is kept at ≥ 4mm safety distance at all sides from other components and equipments. In addition, to ensure
sufficient convection cooling, always maintain a distance of ≥ 20mm from fan ventilated surfaces while the device is in operation.
Please insert an insulation sheet between the system and product, if the safety distance is < 4mm.
