WARNING

Only the correct connector series should be mated with these modules. The 40-784A range uses SMA

connectors for the 6GHz, 18GHz and 26.5GHz modules, and SMA-2.9 connectors for the 40GHz modules. The

user should only mate the correct type to the module, failure to do so may result in damage to the connector.

Also, it is important that the SMA connector’s nut is properly tightened to the correct torque with a 5/16 inch

wrench. This should be 3-5 in·lbs (0.3 to 0.6 N·m) for brass, and 7-10 in·lbs (0.8–1.1 N·m) for stainless steel

connectors.

WARNINGS AND CAUTIONS

WARNING - HAZARDOUS ENVIRONMENTS SYMBOL

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 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 host 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 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:

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.

anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

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

the combined weight of the modules & chassis.

• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the

chassis and the user I/O signals.

• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.

• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on

the front of the unit.
