CAUTION!
The internal LVD contactor ties the "+BAT" terminal to the
power supply "POS" output.
When using the LVD option in a positive ground system do not
ground the positive terminal of the battery. The system must only
have a single ground connection, normally located at the distribution
or load point. An additional ground connection at the battery will allow
current to bypass the internal LVD contactor preventing
disconnection of the battery during a low voltage event.
WARNING!
Battery current through the "+BAT" terminal must not exceed
the maximum current limit rating of the Platinum Series power
supply. Connect the "+BAT" terminal to the external battery
POSITIVE using a suitably rated over current protection and
disconnect device.
Otherwise damage to the unit, load, battery, and personal injury
may occur if the battery is inadvertently connected in reverse
polarity, or the output circuit is over loaded or shorted.
Connect a chassis bonding wire to the ¼ inch ground stud
•
located on the back panel, if required, using 14AWG/1.5mm
or larger wire to bond the power supply chassis to the
external rack system for the installation.
Connect appropriately rated non-energized AC power wiring
•
to the removable AC input connector terminal plug. (AC line
or neutral to either outer connection, safety ground to the
middle pin) using 14AWG/1.5mm
plug to the chassis by tightening the two captive retaining
screws.
Connect the unit to a properly grounded non-energized AC
•
source capable of handling the rated Platinum Series input
current. The building supply circuit must have a branch rated
circuit breaker rated 20A or less.
