Section 2 Installation / Initial Turn-On
Platinum VAX-C Series
2.6 Transmitter AC and Ground Connections
NOTE:
AC connections will be similar across all Platinum VAX-C models. Be sure to
verify all connections using the correct schematic drawings.
The VAX-C does not have an AC ON/OFF switch. Power is applied to the unit by
plugging an energized power cord into the AC connector (IEC C15) on the back of the
unit. All VAX-C power levels will operate over a voltage range of 100 - 240VAC, 50-60
Hz, and is auto ranging.
2.6.1 Surge Suppression Devices
Harris strongly recommends the use of surge protection devices on the incoming AC
mains lines. These devices protect against damages due to transients arising from both
natural and man-made sources. (e.g. lightning and inductive load switching). Clear
preference is to be given to “series” type surge protection devices -- featuring protection
by both a series inductance / shunt capacitor filter and shunt threshold device -- over
simple shunt-only clamping devices. The surge protector must be sized to handle the
full amperage of the load it is protecting (plus a nominal safety margin) and be
connected to the building ground system by short, direct connections. In the case where
the shunt protection elements are protected by a fuse, it is necessary to periodically
check the integrity of the fuse to ensure continued transient protection.
2.6.2 Voltage Regulation
If voltage variations in excess of +/-10% are anticipated, the transmitter power input
must be equipped with automatic voltage regulators (optional equipment) capable of
correcting the mains voltage.
2.6.3 Safety Ground
The VAX-C stand-alone transmitter is equipped with a safety ground lug connection on
the rear panel just below the AC connection (see Figure 2-1). This safety ground should
be connected to the site ground system.
