2.2.1. Work Area
Locate a suitable testing area and be sure you have read all safety
instructions for the operation of the instrument and suggestions on the
test area set-up in the Safety section. Make sure the work area you
choose has a three-prong grounded outlet. Be sure the outlet has been tested for proper wiring
before connecting the instrument to it.
The mains plug is used as the disconnecting device and shall remain
readily operable. The socket-outlet shall be installed near the
equipment and shall be easily accessible
2.2.2. Power Requirements
This instrument requires a power source of either 115 volts AC ± 10%, 50/60 Hz single phase
or 230 volts AC ±10%, 50/60 Hz single phase. Please check the rear panel to be sure the
proper switch setting is selected for your line voltage requirements before turning your
instrument on. For operation at 115 and 230 Volts AC use a 15 A, 250VAC fast-blow fuse.
Do not replace the power supply cord with an improperly rated cord.
For North American: A UL listed and CSA labeled power cord must
be used with the instrument in the United States and Canada. The
power cord must include a NEMA5-15 style male plug, SVT or SJT cord sets, and be rated for
at least 125VAC, 10A, number 16 gauge (or 125VAC, 15A, number 14 gauge) wire or larger,
and the length of the cord does not exceed 2 m must be used. For European: A certified power
supply cord not lighter than light PVC sheathed flexible cord according to IEC 60227,
designation H03 VV-F or H03 VVH2-F (for equipment mass not exceeding 3 kg), or H05 VV-
F or H05 VVH2-F2 (for equipment mass exceeding 3 kg), and be rated for at least 3G 0.75
mm² (for rated current up to 10 A) or 3G 1.0mm² (for rated current over 10 A up to 16 A) wire
or larger, and the length of the cord does not exceed 2 m must be used.
Do not switch the line voltage selector switch located on the rear panel
while the instrument is on or operating. This may cause internal
damage and represents a safety risk to the operator.
2.2.3. Basic Connections
Power Cable
Before connecting power to this instrument, the protective ground
(Earth) terminals of this instrument must be connected to the
protective conductor of the line (mains) power cord. The main plug
shall only be inserted in a socket outlet (receptacle) provided with a protective ground (earth)
contact. This protective ground (earth) must not be defeated by the use of an extension cord
without a protective conductor (grounding).
The instrument is shipped with a three-wire power cable. When the cable is connected to an
appropriate AC power source, the cable will connect the chassis to earth ground. The type of
power cable shipped with each instrument depends on the country of destination.
