warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:

Power Cord Safety
Please read the following safety information carefully before installing the switch:
WARNING
: Installation and removal of the unit must be carried out by qualified personnel only.
• The unit must be connected to an earthed (grounded) outlet to comply with international
safety standards.
• Do not connect the unit to an A.C. outlet (power supply) without an earth (ground)
connection.
• The appliance coupler (the connector to the unit and not the wall plug) must have a
configuration for mating with an EN 60320/IEC 320 appliance inlet.
• The socket outlet must be near to the unit and easily accessible. You can only remove power
from the unit by disconnecting the power cord from the outlet.
• This unit operates under SELV (Safety Extra Low Voltage) conditions according to
IEC 60950. The conditions are only maintained if the equipment to which it is connected also
operates under SELV conditions.

This unit cannot be powered from IT
†
supplies. If your supplies are of IT type, this unit must be
powered by 230 V (2P+T) via an isolation transformer ratio 1:1, with the secondary connection point
labelled Neutral, connected directly to earth (ground).
†
Impédance à la terre
When using a fiber optic port, never look at the transmit laser while
it is powered on. Also, never look directly at the fiber TX port and
fiber cable ends when they are powered on.
Ne regardez jamais le laser tant qu’il est sous tension. Ne regardez
jamais directement le port TX (Transmission) à fibres optiques et les
embouts de câbles à fibres optiques tant qu’ils sont sous tension.
