Delta PMR V320W1AT Series Instruction Manual

Instruction Manual
1. Safety Instructions
• If user's mounting orientation is not according to the recommended mounting orientations,
please consult Delta for further information.
• To ensure sufficient convection cooling, always maintain a safety distance of ≥ 50 mm (1.97
inch) from all ventilated surfaces while the device is in operation.
• The device is not recommended to be placed on low thermal conductive surface.
For example, plastics.
• For safety reason, please ensure the mounted device is kept at 8 ≥ mm safety distance for
D1 from other components and equipment (Refer to Fig. 2.)
The enclosure of the device can become very hot depending on the ambient temperature
•
and load of the power supply. Do not touch the device while it is in operation or
immediately after power is turned OFF. Risk of burning!
• Do not touch the terminals while power is being supplied. Risk of electric shock.
Prevent any foreign metal, particles or conductors from entering the device through the
•
openings during installation. It may cause: Electric shock; Safety Hazard; Fire; Product
failure
The power supply must be mounted by metal screws onto a grounded metal surface. It is
•
highly recommended that the Earth terminal on the connector be connected to the
grounded surface.

1 Input & Output terminal block connector
2 DC voltage adjustment potentiometer
3 DC OK control LED (Green)
3. Installation of the Device
A Base Mounting: Fig. 3 show the mounting hole locations for power supply assembly
onto a metal mounting surface. Fig. 5, only use M4 screw ≤ 3 mm (0.20 inch) through
the base mounting holes. This is to keep a safe distance between the screw and
internal components.
B Fig. 3: Connector
C Fig. 3: This surface belongs to customer's end system or panel where the device is
mounted.
• Use flexible cable (stranded or solid) of AWG 18-12. 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 8 Kgf.cm. (6.94 lbf.in). The insulation stripping
length should not exceed 0.275" or 7 mm. (Refer to Fig. 4).
• Recommended mounting tightening torque: 4~7 Kgf.cm (3.47~6.08 lbf.in).
