Primary Power Cable (Ac/Dc); Ac Power Cable - Black & Decker d984 Installation Manual

Note The primary power AC/DC input feature was not designed, nor
is it suitable as an automatic battery backup provision in the event of
an AC/DC outage. This is because the controller' s externally sourced
input joins with the, internally produced DC. At any given time, the
Controller is taking from the higher of the two voltage sources if there
is as little as a 1V differential. The consequence of this would be to
draw down the DC battery if there were an extended period(s) of re-
duced AC/DC voltage supply.
If you want a backup alternative, one could be configured from a user-supplied
DC power supply with its own backup battery and charger combination along with
appropriate monitoring provisions.
Primary Power Cable (AC/DC)
Ideally, the input AC/DC power lines should be dedicated to the PLC installation to
minimize problems that arise when sharing AC power with electrically " noisy'
equipment.
Provide for strain relief by installing a service loop and cable restraint on the pri-
mary power cable as its connector is not locked in place.
AC Power Cable
The recommended AC power cable should consist of three insulated leads of
Number 14 AWG stranded copper. The cable leads insert in the plug-in power
cable connector shipped installed in the AC input connector jack from the factory.
The color code (standard) for the AC cable is white for AC neutral, black for AC
hot, and green for factory or earth ground. The European color code is light blue
instead of white for neutral, brown instead of black for the hot wire, and green/yel-
low instead of green for ground.
Your AC source cable must be suitable for supplying 115/230 Vat at 5A peak for
the turn-on surge and 0.4 continuous at worst-case, low voltage conditions at
60" c.
