Chapter 10: Site Preparation – Power Requirements for Older Systems: Series 3 Power Requirements and Connections (Prior to May 2000)
Power Recommentations
Agilent makes the following recommendations:
■ 3-phase power should be used if it is available.
■ A separate ac mains service should be provided
for the test system.
■ Copper wire should be used for the system input.
■ The service must have a mains disconnect
installed adjacent to the system so that power can
be quickly removed in case of an emergency. The
E1135C PDU, used with 3070 Series 3 and 79000
systems, contains a mains disconnect. This input
mains disconnect switch does not have
short-circuit or over-current protection. The
E1135C output terminals do have both
short-circuit and over-current protection.
■ A 25.4-millimeter (1-inch) hole is provided on the
PDU for the electrician to install a cable clamp
and power cord. Agilent recommends the use of a
power cord
E1135-61611 - uses #10 AWG
5-conductor cord with NEMA plug that mates
with NEMA L21-30. Used by North America.
Receptacle available locally. or a hard-wired
connection.
■ The system input power connections on the PDU
are made to an input connector block and the
ground connection to the chassis. In the E1135C
the power is connected to the mains disconnect
switch and a ground terminal attached to the
chassis. These connectors can accept wire up to
10 square millimeters (#8 AWG). For ease of
installation, in areas where it meets local code
requirements, Agilent recommends that you use
multi-strand wire from a box to the PDU.
■ If needed, convenience outlets must be located
near the system for external equipment, including
for test servers, optional extra equipment bays,
and automation equipment. Locate the outlets
within one meter (three feet) of and directly
behind the device. See Chapter 3 to plan the
location of convenience outlets. All convenience
outlets must supply 20 amps at 100–120 volts or
10 amps at 200–240 volts, whichever is
applicable.
The power requirements for older 3070 Series 3 and
79000 family systems are shown in
Table 10-8 on
page 10-84 (3-phase) and
Table 10-9 on page 10-86
(single-phase). The values shown in brackets [ ] are
currents when the DUTS and controller are configured
at 100-120 volts. The other values are currents with the
DUTS and controller configured for 220-240 volts (See
Chapter 11,
Site Preparation – Series 3 / 79000
Current Reduction Conversion).
The maximum current or full-load amps (FLA) assumes
fully-loaded systems with Serial Test Card power
supplies. Note that the operating frequency range for the
3070 / 79000 family systems is 47–63 hertz, with the
nominal line frequency either 50 hertz or 60 hertz.
