WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically 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 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.
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 specication, 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 classied 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 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.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL
Suitably qualied & trained users should ensure that the accompanying documentation is fully read
and understood before attempting to install or operate the product.

SAFETY INSTRUCTIONS
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.

Model 40-656A-001 is a 38-channel multiplexer with
2-pole switching, suitable for switching signals to 2 Amp,
220VDC/125VAC. It offers the highest density in its class for
medium power/voltage signals.
This multiplexer has been specically designed for switching
POTS, ISDN or xDSL telephony signals. Bandwidth for most
congurations is typically >25MHz. It is paired with a very similar
module, the 40-655A-002, a multi-banked multiplexer.
The 40-656A can be operated as a conventional multiplexer
with break-before-make action when a new channel is selected.
Alternatively, product variants can be supplied that allow multiple
channels to be simultaneously selected.
The 40-656A channel selection congurations have been revised
from the 40-656. The 40-656A defaults to single channel selection
with multiple channel selection variants dened by use of a sufx.
Please contact Pickering sales ofce for more assistance with
Telecom switching applications.
