Meaning/Description Symbol
PROTECTIVE EARTH (GROUND)
To identify any terminal which is intended for connection to an
external conductor for protection against electric shock in case of a
fault, or the terminal of a protective earth (ground) electrode.
DANGEROUS VOLTAGE
To indicate hazards arising from dangerous voltages.
WARNING/CAUTION
An appropriate safety instruction should be followed or caution to a
potential hazard exists.
Refer to the relevant instructions detailed within the product
manual.
HEAVY
If this product is heavy reference should be made to the safety
instructions for provisions of lifting and moving.
STATIC SENSITIVE
To indicate that static sensitive devices are present and handling
precautions should be followed.

Warnings & Cautions
WARNING - Hazardous Environments Symbol
This product is not specifically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user ensures
suitable protective measures are taken.
!
CAUTION - Handling of Electrostatic-Sensitive Devices Symbol
Certain semiconductor devices used in this equipment are liable to damage due to static voltage. Observe the
following precautions when handling these devices in their unterminated state, or sub-assemblies containing
these devices:
• Persons removing sub-assemblies from equipment using these devices must be earthed by a wrist strap
and a resistor at the point provided on the equipment.
• Soldering irons used during the repair operations must be low voltage types with earthed tips and isolated
from the mains voltage by a double insulated transformer.
• Outer clothing worn must be unable to generate static charges.
• Printed Circuit Boards (PCBs) fitted with these devices must be stored and transported in anti-static bags.
WARNING - Danger of Electric Shock Symbol
This module may contain hazardous voltages. Before removing the module from the rack remove all supplies
and disconnect user I/O signals.
Unused slots in the PXI/PXIe/LXI chassis are populated with blanking plates to prevent access to user I/O
signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths.
If the product is not used in this manner for example by using an extender card then additional care must be
taken to avoid contact with exposed signals.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This module must not be used for the switching of Mains Circuits. For the switching of voltages up to the
module’s full specification, Secondary Circuit power supplies and the Device Under Test must be fully isolated
from the Mains Circuit and the safety earth.
The host chassis must be correctly installed and be connected to mains or factory safety ground, please refer
to your chassis installation manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classified as Overvoltage Category II up to
300V. Separation between the Secondary Circuit and Mains Circuit is achieved by a transformer in which the
primary windings are separated from the secondary windings by reinforced insulation, double insulation, or a
screen connected to the protective conductor terminal.
