Fitting and commissioning is to be carried out by quali-
fied personnel only in accordance with the operating
instructions.
Such qualified personnel must have several years of
training and experience in installing and commissioning
electrical and pneumatic industrial control systems.
• Please observe the applicable safety requirements
and standards.
Conversion or extension of the product with modules,
for which the Recognized Component Mark of UL does
not apply, will lead to loss of the UL certification.
• Contact Festo if you require information on UL-certi-
fied modules.
Only for connection to a NEC Class 2 supply
Raccorder Uniquement a un circuit de Classe 2
This device is intended to be used with a Class 2 power
source or Class 2 transformer in accordance with UL1310
or UL1585.
As an alternative a LV/C (Limited Voltage/Current) power
source with one of the following properties can be used:
This device shall be used with a suitable isolating source
such that the maximum open circuit voltage potential
available to the product is not more than 24 V DC and the
current is limited to a value not exceeding 8 A measured
after 1 minute of operation.
This device shall be used with a suitable isolating source
in conjunction with a fuse in accordance with UL248. The
fuse shall be rated max. 4 A and be installed in the
24 V DC power supply to the device in order to limit the
available current.
Note that, when more than one power supply or isolating
device is used, connection in parallel is not permitted.
