SAFETY CONSIDERATIONS
GENERAL
This product and related documentation must be reviewed for familiarization with safety markingsand
instructions before operation.
This product is a Safety Class
I instrument (providedwith a protective earth terminal).
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage and the correct fuse is installed. Refer
to Section II, Installation.
SAFETY EARTH GROUND
An uninterruptible safety earth ground must be provided from the mains power source to the product
input wiring terminals or supplied power cable.

SAFETY INFORMATION
I]
Any interruption of the protective grounding conductor (insideor outside the instrument)or discon-
necting the protective earth terminal will cause a potential shock hazard that could result in personal
injury. (Groundingone conductor of a two conductor outlet 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 this instrumentistobeenergizedviaan autotransformer (forvoltage reduction

terminal is connected to the earthed pole terminal (neutral)of the power source.
Instructions for adjustments while covers are removed and for servicing are for use by service-trained
personnel only. To avoid dangerous electric shock, do not perform suchadjustments or servicing unless
qualified to do so.
For continued protection against fire, replace the linefuse(s~only with
250V fuse(s)of the same current
rating and type (forexample, normal blow, time delayi. Do not use repaired fuses or short circuited
fuseholders.
When measuring power line signals, be extremely careful and always use a step-down isolation trans-
former whose outputvoltage is compatible with the input measurement capabilitiesof this product.This
product's front and rear panelsare typically at earth ground, so
NEVER TRY TO MEASURE AC POWER
LINE SIGNALS WITHOUT AN ISOLATION TRANSFORMER.
