WARNING - HAZARDOUS ENVIRONMENTS
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.
WARNING - DANGER OF ELECTRIC SHOCK
This unit may contain hazardous voltages. Before removing the unit from the rack remove all supplies
and disconnect user I/O signals.
If the unit has removable modules, unused slots in the chassis must be populated with blanking
panels to prevent access to user I/O signals that may be present. Blanking panels are available to
order from Pickering. 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 unit must not be used for the switching of Mains Circuits. For the switching of voltages up to the
unit'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 chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to the installation section of this 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.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES
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:
1. 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.
2. 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.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) fitted with these devices must be stored and transported in
anti-static bags.
