Overvoltage Categories

This product conforms to the safety requirements for CAT I 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

CAT III

CAT IV

Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)

Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to
outlets.

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

Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.

To avoid electric shock, do not remove the product's case. The

DANGER

WARNING

internal components of the product carry high voltages and may
become very hot during operation.
The vinyl shield on the 9615-01 H.V. TEST LEAD alligator clip is not
high voltage insulated. Do not touch when high voltage is applied.

To avoid electric shock, do not allow the product to get wet, and do
not use it when your hands are wet.
To avoid electric shock, be sure to connect the protective ground
terminal to a grounded conductor.
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.

CAUTION

NOTE

To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging the cord from the power outlet.
To avoid damaging the 9615-01, 9615-02 H.V. TEST LEAD, do not kink or
pull on the leads.
For safety reasons, when taking measurements, only use the 9615-01,
9615-02 H.V. TEST LEAD provided with the product.
To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.

Do not use the product near a device that generates a strong electromagnetic field or
electrostatic charge, as these may cause erroneous measurements.

Chapter 1

Overview

1.1 Product Introduction

The 3930 is a passive auxiliary tester that is connected to and controlled by
a master unit (the 3153 AUTOMATIC INSULATION/WITHSTANDING
HiTESTER, or a sequencer). The 3930 cannot operate on a standalone
basis.
This auxiliary tester is designed to safely permit testing of multiple locations
with a minimum of connection changes. This unit can output from any
channel high voltage that is input through a high-voltage input cord simply
by turning the internal high-voltage relays on and off. Up to four of these
units can be connected to a single master unit, with each unit identified by a
unique ID.

1.2 Features

In order to prevent electric shock, use voltage to ground that is at or

WARNING

less than the SELV* on the LOW side of the high-voltage input cords.
Although the LOW side of the high-voltage input cords is functionally
insulated from ground, there is no withstand voltage.
*: SELV (separated external low voltage): effective value of 30 V, peak

value of 42.4 V

(1) Direct connection to the 3153

The 3930 can be directly connected to the 3153 AUTOMATIC
INSULATION/WITHSTANDING HiTESTER. Because the 3153 supplies
power to the 3930, no separate power supply is needed.

(2) Single mode and Multi-mode

The 3930 has two operation modes: single mode and multi-mode. Single
mode permits testing of eight channels using the one COM channel and
eight high-output channels. Multi-mode permits testing of four pairs of two
different high-output channels.

(3) Multiple channels

In single mode, the 3930 can test eight channels. In multi-mode, the 3930
can test four channel pairs. In addition, a unique ID can be set for each unit,
allowing a maximum of four 3930s to be connected to a single master unit.

(4) Output channel indicators

The LEDs on the front panel indicate the current mode and the channels that
are being output.

(5) Insulated design

The power supply, the high-voltage inputs and outputs, and the control input
connector signal wires are all functionally insulated.

(6) Signal level from 5 to 24 V

Devices ranging from general logic to a sequencer can be connected by
selecting the supply voltage for the control signal system.

(7) Safe design that avoids duplicate IDs

When multiple 3930s are connected, the unit can detect incorrect (duplicate)
ID settings. When a mistake is detected, all output is shut off.
