Safety Considerations – Line Voltage and Fuses

The wiring polarity of a properly wired connector is shown in Table 1-1 for both US line cords and European
line cords that follow the “harmonized” wiring convention.

Line Neutral Earth Ground
US Black White Green
European Brown Light Blue Green/Yellow
If you have any doubts about the line cord for use with your Reference 30k Booster, please contact qualified
electricians or instrument-service technicians for assistance. They can perform a simple continuity check to
verify the connection of the Reference 30k Booster chassis to earth, and check that the line cord is suitable for
1.5 kW power. Note that these checks only verify the safety of your Reference 30k Booster AC power
connections —they do not verify safety of the system used for a specific application.
Line Voltage and Fuses
The Reference 30k Booster can be safely operated at two nominal line power (mains) voltages: 115 V
AC
and
240 V
AC
. Table 1-2 shows the allowed range of input voltage for each nominal line-voltage setting. AC power-
line (mains) frequency must be between 47 and 65 Hz.
Table 1-2. AC Voltage Ranges for Each Nominal Line-voltage Setting
Nominal Setting Allowed Range Fuse Rating Schurter P/N
115 90 to 130 V
AC
12.5 A 250 V
AC
0034.3128
240 215 to 264 V
AC
6.3 A 250 V
AC
0034.3125
The instrument automatically switches to use any power-line (mains) voltage in these ranges: however, safe, full
power operation in each range requires different AC power-line fuses as noted above.
Gamry Instruments has attempted to ship your Reference 30k Booster configured for the power-line (mains)
voltage in your area. The fuses installed in the Reference 30k Booster should be the correct values for the AC
line (mains) voltage prevalent in your area. Spare fuses appropriate for your line voltage have also been
included. If an error was made in the fuse selection, please contact Gamry Instruments or your local sales
representative to get the correct fuses.
Warning:
You can damage a Reference 30k Booster by attempting to operate it with
incorrect power line fuses. It is dangerous to plug a unit fused for operation at 100 VAC or 120 VAC into a
higher mains voltage such as 220 VAC. A power-supply fault under these conditions could create a fire or
shock hazard.
Warning:
If you replace the line cord, you must use a line cord with the same polarity and
power rating as that supplied with the Reference 30k Booster. An improper line cord can create a safety
hazard, which could result in personal injury or death.
