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 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/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.

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.

CAUTION - PRODUCT DOCUMENTATION

Suitably qualified & trained users should ensure that the accompanying documentation is fully read

and understood before attempting to install or operate the product.

SAFETY INSTRUCTIONS

All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O

signals (refer to the Maintenance Section).

• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
