The S&C Voltage Sensor is mounted on the jaw-contact side of the
switch, on the center phase.

Current sensors must not be installed on unshielded cables or on
cables where the insulation is exposed but ungrounded (for example,
where dielectric tape or heat-shrink tubing is used). These sensors are
intended for application at ground potential and may be damaged by the
voltage gradient between the cable insulation and ground.
3
The S&C Battery Charger is factory-calibrated to accommodate the
loads furnished in the Communication and Control Equipment Group at
the time of shipment. If additional loads are subsequently added. S&C
recommends recalibration of the charging output to the batteries to
ensure optimal battery life. Refer to your nearest S&C Sales Offi ce.

The battery charger and battery packs are not intended to provide
power to any user-furnished and installed equipment.
6
Current and voltage sensing are not included and cannot be pro-
vided.
