INSTALLATION
3.1
Safety Information
The 9400A has been designed to operate from a single-phase power source
with one of the current-carrying conductors (neutral conductor)
ground (earth) potential. Operation from power sources in which both
current-carrying conductors are live with respect to ground (such as
phase-to-phase on a tri-phase system) is not recommended, as the 9400A
is equipped with over-current protection for one mains conductor only.
The 9400A is provided with a three-wire electrical cord containing a
three-terminal polarized plug for mains voltage and safety ground
connection. The plug’s ground terminal is connected directly to the
frame of the unit. For adequate protection against electrical hazard,
this plug must be inserted into a mating outlet containing a safety
ground contact.
3.2 Operating Voltage
Prior to powering up the unit, make certain that the mains voltage for
your area corresponds to the mains voltage value appearing in the
window of the selector box at the rear of the 9400A.
The operating voltage for the 9400A is either 115 V or 220 V at 48 to
62 Hz. Switching from one mains voltage to another is not possible. If
the mains voltage appearing in the window differs from that used in
your area contact the nearest LeCroy sales office or distributor.
*CAUTION*
If a 9400A set for 115 V is plugged into a 220 V power source, severe
damage can occur. Before powering up the unit, ensure that the corect
line voltage has been set.
