25.9. E
The unit is tested and approved for branch circuits up to 20A. External protection is only required if the supplying
branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and
local requirements.
If an external fuse is necessary or utilized, a minimum value is required to avoid undesired tripping of the fuse.
25.10. O
25.11. U
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. The inside temperature defines the ambient temperature for the power supply.
Results from such an installation:
Power supply is placed in the middle of the box, no other heat producer inside the box

Instructions for two phase operation:
a)
b)
Appropriate fuses or circuit breakers are specified in section 25.9
“External Input Protection”.
20A
A phase to phase connection is allowed as long as the
supplying voltage is below 240V
Use a fuse or a circuit breaker to protect the N input. The
N input is internally not protected and is in this case
connected to a hot wire.
