color:#434343" class=""> 690.12 does not specify where you
should locate the
initiating device or what type of device you must install.
This lack of detail
is intended to provide system integrators and AHJs with the
flexibility to
adapt rapid-shutdown solutions to the complexities of the
built environment.
While the best location for a rapid-shutdown device and the
required label is
typically at or near the service equipment, the fire service
may have
preplanned emergency response tactics for some large
commercial or industrial
buildings that favor a different location.</span><span

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Helvetica

mso-bidi-font-family:"Helvetica
Neue";color:#434343" class="">One of the simplest ways
to initiate rapid shutdown is to set it up to occur
automatically upon loss of
ac power. This is why <i class="">NEC 2014 </i>does not
require a specific
type of rapid-shutdown initiation device. If you install a
roof-mounted
residential microinverter system or a commercial PV system
using roof-mounted
string inverters located within 10 feet of the array, you do
not need any
special equipment to initiate rapid shutdown; you can
accomplish this function
simply by interrupting utility-supplied power to the
inverters. Some companies
have developed various rapid-shutdown switches, and claim
that rapid shutdown
requires these extra switches. However, you have to install
an extra
rapid-shutdown switch only when you need to turn the array
off by some means
other than loss of utility power, as with battery-backup
systems or inverters
equipped with a daytime backup-power outlet.</span></p>

color:#434343" class="">690.12 does not specify how many
buttons, switches or movements
of the hand are allowed to complete rapid shutdown. Ideally,
the process should
only require one action. As written today, however, the
language in 690.12
provides system integrators and AHJs with the flexibility to
consider alternatives.
Note that if the system design requires more than one action
to initiate rapid
shutdown, the 10-second time limit still applies. Therefore,
where systems are
deployed with more than one initiation device or switch,
they should all be in
close proximity so that emergency personnel can de-energize
all of the PV
system circuits on the building within 10 seconds. Further,
labeling must
clearly identify all of the initiation devices and all of
the steps required to
complete rapid shutdown.<o:p class=""></o:p></span></p>
