TECHNICAL DATASHEET
PMF Panel Mount Power Supply
4.2V 231W 1 Phase / PMF-4V320WC□□
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 of maximum 5mm (0.20 inch) length (Refer to
Fig. 4). 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 of maximum 4mm (0.16 inch) length (Refer to
Fig. 4). This is to maintain a safety distance between the screw and internal components.

Fig. 2 Recommended Mounting Orientations
• 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.
Safety Distance
D1 = 4.0mm Min.
D2 = 20.0mm Min.
Fig. 3 Mounting Hole Locations and the Safety Distance
Ensure the mounted device is kept at ≥ 4mm safety distance at all sides from other components and equipment. In addition, to ensure
sufficient convection cooling, always maintain a distance of ≥ 20mm (0.78 inch) from ventilated surfaces while the device is in
operation.
 Only use M4 screw ≤ 5mm (0.20 inch) through the base mounting holes
at Ⓐ. This is to keep a safe distance between the screw and internal
components.
 Only use M4 screws ≤ 4mm (0.16 inch) through the base mounting
holes at Ⓑ. This is to keep a safe distance between the screw and
internal components.
