2.2. Installation
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 setup in section 1.4. Safety.
Make sure the work area you choose has a three-prong grounded outlet capable
of supplying the necessary input current to the power source. 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. Before applying
power verify that the instrument is set to the correct line voltage (115 or 230 volts).
Adjust the voltage select switch to 115 for use with a 115 volt input. Adjust the
voltage select switch to 230 for use with a 230 volt input. See section 3.2.2. Rear
Panel Controls for an image of the rear panel.
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.
The SC6540 must be connected to a good ground. Be
certain that the power wiring is properly polarized and that
