I can't find any requirements that the Alert symbol should be included in

Shall it be included in the DoC or not?

Hello,
I'm not aware of any requirement for it to be on the DoC. Just the
equipment, the packaging and the user manual.
I find this labelling guidance document very useful:

Hello Amund,
The Alert symbol shall also be affixed on the package, but not on the DoC.

This discovery has a lot of potential. A self-monitoring battery could easily
signal for help or open an interlock. If caught early enough, a thermal
runaway might be averted. This could be especially important on large devices
like electric vehicles or charge controllers.
Part of it may because of failure to pass down info about resources. There
has been significant turnover in corporate compliance billets for at least 8
years. The newbies may not be aware of this resource.
At the last two meetings of the San Diego PSES chapter, I have

Folks,
is it necessary to have the CCC mark to ship a router to China?
Can we ship with CE mark?
the router is powered by a 12VDC wall mount adapter and has 3 FE ports.
NO telecom port or Wi-Fi.
thanks in advance for you help.

The Queen Mary 2 was totally without power for at least an hour when a
capacitor bank exploded, blowing the reinforced steel door off of a power
cabinet (like those used in enclosed power substations). The capacitors
are used to filter harmonics from the electronic drive for the electric

We are trying to comply with the requirements of section 1.7.3 of the Machinery
Directive regarding the Year of Construction.
Do I have to use a four digit year or can I use just the last two digits?
Can the year be coded to where it is not apparent except for the manufacturer?

At first glance, I would guess that this is intended to cover the DC-DC
converter that an EV would need to provide power to electrical systems such as
headlights, turn signals, heater fan, etc. I'm puzzled by the rating in the
scope of up to 250Vac at 50/60Hz though.

QUOTE from Don Borowski: A number of capacitors in the capacitor bank
were later found to be bulging from overheating. The equipment to monitor
the condition of the capacitors (by monitoring electrical parameters) did
not catch the developing problem before the explosion.
Bulging capacitors
Considering the size of the country, the population and the surge in electrical
goods, I find the number in China (2) and India (1) quite surprising!!

Perhaps not. Most India and China factories do not control the design; which
tends to orginate from Japan or the western world. Or space aliens.
Regulatory for post-design is materials and process control, so no need for

Scott,
What is one of the key concepts you keep hearing about electric vehicles
and when they are plugged in to the grid for re-charging? That is
returning power to the grid when the grid needs it and the car is
already charged (taking power from the battery and sending it off to the
grid).
I haven't worked with those batteries since 2005, but back then, they, the
batteries for cars, were very intensely monitored and controlled as part of the
package that held batteries and control circuits. Cost reductions since then
could have removed a bunch of circuits.
