Safety Notes
__________________________________________________________________________________________________
WARNING This product is designed to conform to IEC 61010 Safety Standards,
and has been thoroughly tested for safety prior to shipment. However,
mishandling during use could result in injury or death, as well as
damage to the product. Be certain that you understand the
instructions and precautions in the manual before use. We disclaim
any responsibility for accidents or injuries not resulting directly from
product defects.
The symbol printed on the product indicates that the user
should refer to a corresponding topic in the manual (marked with
the symbol) before using the relevant function.
In the manual, the symbol indicates particularly important
information that the user should read before using the product.
Indicates a grounding terminal.
Indicates AC (Alternating Current).
Indicates a fuse.

Safety Notes

Overvoltage Categories
This product conforms to the safety requirements for CAT II measurement
products.
To ensure safe operation of measurement products, IEC 60664 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called overvoltage categories. These are defined as follows.
CAT I Secondary electrical circuits connected to an AC electrical outlet
through a transformer or similar device.
CAT II Primary electrical circuits in equipment connected to an AC
electrical outlet by a power cord (portable tools, household
appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed installations)
connected directly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT IV The circuit from the service drop to the service entrance, and to
the power meter and primary overcurrent protection device
(distribution panel).
Higher-numbered categories correspond to electrical environments with
greater momentary energy, so a measurement product designed for CAT III
environments can endure greater momentary energy than one designed for
CAT II. Using a measurement product in an environment designated with a
higher-numbered category than that for which the product is rated could
result in a severe accident, and must be carefully avoided.

Notes on Use
__________________________________________________________________________________________________
WARNING Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the product
and present an electrical hazard.
To avoid electric shock and ensure safe operation, connect the
power cable to a grounded (3-contact) outlet.
Use this unit near the power supply socket.
The interior of the unit contains some components which are
subject to high voltage, and therefore dangerous. Absolutely do
not remove the cover panel.
CAUTION Various connectors are present on the outside of the 3511-50. Never
connect any cable to any of these connectors without first turning off the
power supply and removing the power cord. Moreover, check the
connections carefully in order to avoid any chance of setting up a short
circuit etc..
In the event that the equipment malfunctions in any manner during use,
turn off the power immediately, and contact your dealer or HIOKI
representative.
Do not store or use the unit where it will be exposed to direct sunlight,
high temperatures, high humidity, or condensation. If exposed to such
conditions, the unit may be damaged, the insulation may deteriorate, and
the unit may no longer satisfy its specifications.
This product should be installed and operated indoors only, between 0
and 40 and 35 to 80%RH. However, it can be safely operated down to
-10 .
The unit should always be stored in a range from -10 to 55 , 80% RH
or less.
Do not store or use the product where it could be exposed to direct
sunlight, high temperature or humidity, or condensation. Under such
conditions, the product may be damaged and insulation may deteriorate
so that it no longer meets specifications.
Do not drop the unit or subject it to severe shock. Doing so can cause
serious damage.
To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
Notes on Use
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
Warranty
HIOKI cannot be responsible for losses caused either directly or indirectly by
the use of the unit with other equipment, or if ownership is transferred to a
third party.
