Power Requirements
AC power safety
It is important to know the power capacity of the building’s wiring facilities.
— For voltages below 200 V, two entirely separate power cords (provided with
the E7515B) must be used. Make sure the plugs for each power cord are
protected with independent and properly sized circuit breakers, with margin
to provide the required power. Power strips are not allowed.
— For facilities with voltages above 200 V, a single power cord with a
Y-adapter may be used to connect both of the instrument’s AC inputs to a
single wall plug. Make sure the circuit breaker for the line is properly sized,
with margin to provide the required power.
Figure 1-2 Grounding cable (needed if a Y-adapter power input is used)
If a Y-adapter is used, a ground cable (not provided by Keysight) must be
connected from the ground stud (at the lower left corner of the E7515B rear
panel) to a proper ground socket of the building. Install the cable as illustrated
below. The minimum required cross-section of the cable is 14AWG and O-ring
size is M4.
The power cords are connected to internal capacitors which may remain live for
5 seconds after disconnecting the plugs from their power supply.
