Attention — refer to the manual. This symbol indicates that information about
the usage of a feature is contained in the manua
l.
Power Source
The 5725A is intended to operate from a power source that will not apply more than
264V ac rms between the supply conductors or between either supply conductor and
ground. A protective ground connection by way of the grounding conductor in the power
cord is essential for safe operation.
Use the Proper Fuse
To avoid fire hazard, use only the fuse specified on the line voltage selection switch
label, and which is identical in type voltage rating, and current rating.
Grounding the 5725A
The 5725A is Safety Class I (grounded enclosure) instruments as defined in IEC 348.
The enclosure is grounded through the grounding conductor of the power cord. To avoid
electrical shock, plug the power cord into a properly wired earth grounded receptacle
before connecting anything to any of the 5725A or 5700A terminals. A protective ground
connection by way of the grounding conductor in the power cord is essential for safe
operation.
Use the Proper Power Cord
Use only the power cord and connector appropriate for proper operation of a 5725A in
your country.
Use only a power cord that is in good condition.
Refer cord and connector changes to qualified service personnel.
Do Not Operate in Explosive Atmospheres
To avoid explosion, do not operate the 5725A in an atmosphere of explosive gas.
Do Not Remove Cover
To avoid personal injury or death, do not remove the 5725A cover. Do not operate the
5725A without the cover properly installed. There are no user-serviceable parts inside
the 5725A, so there is no need for the operator to ever remove the cover.
Do Not Attempt to Operate if Protection May be Impaired
If the 5725A appears damaged or operates abnormally, protection may be impaired. Do
not attempt to operate it. When is doubt, have the instrument serviced.
