External Supply Protection
The mains power cord supplied with this product is rated at 10A maximum and
must be protected from overload by an external fuse or circuit breaker.
Fused Plugs (UK-style)
If the power cord is fitted with a UK-style BS1363 3-pin plug (i.e. with provision for an internal fuse),
then it must be fitted with a BS1362 ASTA approved 1 inch cartridge fuse.
This fuse must be rated at a maximum of 10A/250V. Since the current draw of the PSU is less than
1A, a fuse of a lower rating not less that 3A/250V may be used.
WARNING: Never attempt to fit a fuse or circuit breaker of a higher maximum rating than shown
above.
Unfused Plugs or Hard-wired
If the power cord is fitted with an unfused plug, or is hard-wired into a power strip (mains distribution
batten), then the power cord must be protected by an external fuse or circuit breaker of a rating shown
in the table below:
Supply Voltage 110V nominal 230V nominal
Maximum Fuse Rating 10A 10A
Minimum Fuse Rating 3A 3A
WARNING: Never attempt to fit a fuse or circuit breaker of a higher
maximum rating than shown above.
