Safety Considerations
General
This product and related documentation must be reviewed for familiarisation before operation. If the equipment is used in a
manner not specified by the manufacturer, the protection provided by the instrument may be impaired.
Before Applying Power
Verify that the product is set to match the available line voltage and the correct fuse is installed.
Before Cleaning
Disconnect the product from operating power before cleaning.
WARNING
Bodily injury or death may result from failure to heed a warning. Do not proceed beyond a warning until the indicated conditions
are fully understood and met.
CAUTION
Damage to equipment, or incorrect measurement data, may result from failure to heed a caution. Do not proceed beyond a
caution until the indicated conditions are fully understood and met.
This equipment must be earthed
An uninterruptible safety earth ground must be maintained from the mains power source to the product’s ground circuitry.
WARNING
When measuring power line signals, be extremely careful and use a step down isolation transformer whose output is compatible
with the input measurement capabilities of this product. The product’s front and rear panels are typically at earth ground. Thus,
never try to measure AC power line signals without an isolation transformer.
WARNING
Instructions for adjustments when covers are removed and for servicing are for use by service-trained personnel only. To avoid
dangerous electrical shock, do not perform such adjustments or servicing unless qualified to do so.
WARNING
Any interruption of the protective grounding conductor (inside or outside the instrument) or disconnecting of the protective earth
terminal will cause a potential shock hazard that could result in personal injury. Grounding one conductor of a two conductor out-
let is not sufficient protection.
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be secured against any
unintended operation.
If the instrument is to be energised via an autotransformer (for voltage reduction) make sure the common terminal is connected to
the earthed pole terminal (neutral) of the power source.
Instructions for adjustments while the covers are removed and for servicing are for use by service-trained personnel only. To avoid
dangerous electrical shock, do not perform such adjustments or servicing unless qualified to do so.
For continued protections against fire, replace the line fuse(s) with fuses of the same current rating and type (for example, normal
blow time delay). Do not use repaired fuses of short-circuited fuse holders.
