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 dista
nce 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 f
ro
m 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.

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, o
nly
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.

•
U
se 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).
