The following safety precautions apply to both operating and maintenance personnel and must
be followed during all phases of operation, service, and repair of this instrument.
Before applying power to this instrument:
Read and understand the safety and operational information in this manual.
Apply all the listed safety precautions.
Verify that the voltage selector at the line power cord input is set to the correct line
voltage. Operating the instrument at an incorrect line voltage will void the warranty.
Make all connections to the instrument before applying power.
Do not operate the instrument in ways not specified by this manual or by B&K Precision.
Failure to comply with these precautions or with warnings elsewhere in this manual violates the
safety standards of design, manufacture, and intended use of the instrument. B&K Precision
assumes no liability for a customer’s failure to comply with these requirements.
Category rating
The IEC 61010 standard defines safety category ratings that specify the amount of electrical
energy available and the voltage impulses that may occur on electrical conductors associated
with these category ratings. The category rating is a Roman numeral of I, II, III, or IV. This rating
is also accompanied by a maximum voltage of the circuit to be tested, which defines the voltage
impulses expected and required insulation clearances. These categories are:
Category I (CAT I): Measurement instruments whose measurement inputs are not intended to
be connected to the mains supply. The voltages in the environment are typically derived from a
limited-energy transformer or a battery.
Category II (CAT II): Measurement instruments whose measurement inputs are meant to be
connected to the mains supply at a standard wall outlet or similar sources. Example
measurement environments are portable tools and household appliances.
Category III (CAT III): Measurement instruments whose measurement inputs are meant to be
connected to the mains installation of a building. Examples are measurements inside a
building's circuit breaker panel or the wiring of permanently-installed motors.
Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be
connected to the primary power entering a building or other outdoor wiring.
Do not use this instrument in an electrical environment with a higher category rating than what
is specified in this manual for this instrument.
You must ensure that each accessory you use with this instrument has a category rating equal
to or higher than the instrument's category rating to maintain the instrument's category rating.
Failure to do so will lower the category rating of the measuring system.
Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The
mains power should be between 190 V to 250 V RMS. Use only the power cord supplied with
the instrument and ensure it is appropriate for your country of use.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cabinet must be connected to an
electrical safety ground. This instrument is grounded through the ground conductor of the
supplied, three-conductor AC line power cable. The power cable must be plugged into an
approved three-conductor electrical outlet. The power jack and mating plug of the power cable
meet IEC safety standards.
Do not alter or defeat the ground connection. Without the safety ground connection, all
accessible conductive parts (including control knobs) may provide an electric shock. Failure to
use a properly-grounded approved outlet and the recommended three-conductor AC line
power cable may result in injury or death.
Unless otherwise stated, a ground connection on the instrument's rear panel is for a reference
of potential only and is not to be used as a safety ground.

12.5 Remote_Inhibit
The Instrument offers a remote inhibit used to turn the output off. The voltage level of pin
19 (Remote_inhibit) (reference ground is DGND) has to be set high (5 V) first, or the
Instrument will enter into protection mode. If the voltage level drops to 0 V, the
Instrument will stop outputting, and will show ‘Error Remote Inhibit ON’.
Follow the settings: Configure → Config 2 → Remote_Inhibit → ON
The RS232 interface does not support flow control. The programmer should be
aware of this limitation and pay attention to the Instrument command process
time. If the remote commands are sent too fast the internal buffer may overrun
and cause communication errors. Therefore, it is mandatory to add a delay
between commands so that the Instrument has sufficient time to process.
