Rear Panel
The rear panel of the 4314Ki may vary from unit to unit based on the features installed. If the 4314Ki that
you are using features terminals or connectors that are not described in this section, please refer to any
available addendum that references the particularities of your model.
Fuse Holder
The fuse holder is mounted on the rear panel and contains a 2 amp in-line fuse. This fuse is designed to
protect the battery pack from excessive charging currents. For continued protection, replace the line fuse
only with fuse of the same voltage and current rating and type. DO NOT use repaired fuses or short-
circuited fuse holders.
Charger/Power Receptacle
The battery charging jack is a barrel type and is located on the 4314Ki rear panel. The center pin of the
connector is positive. The charging requirements of the internal battery pack are 9VDC @ 300mA. The
device can however accept 6 to 9Vdc @ 300mA to 1.25A. The correct charging voltage is supplied by the
adapter included with the instrument. Additional adapters are available as Option "A2". The charger is
equipped with a locking ring and is sealed IP68.
RS-232 Connector
The RS-232 interface of the 4314Ki is an ultra-safe isolated serial Interface. The digital signals are
transmitted across the isolation barrier using iCoupler technology. The RS-232 serial interfacing is done
through the 9-pin female D-Sub connector located on the rear panel of the instrument. Knowledge of the
specific pin functions of the serial connector may be necessary for certain applications; see chapter 6
(Remote Interface) for connector pin assignment.
Power Mode Switch
Power Mode Selection Key Switch allows the use to select Battey or Continuous Power Mode.
