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 excee-
ding 8 amperes 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.

Extracts )* from the UL report:
Conditions of acceptability
(File E239998, Command units):
In determining the acceptability of the combination, the
following details should be examined.
– The mounting suitability shall be determined in the end-
use.
– Devices should be used within its recognized ratings as
specified above (technical data).
– The devices have not been investigated for field-wiring.
The suitability should be determined in the end-use
application.
– If the programmable controller is provided with output
wires which are not UL listed or recognized these wires
Note
have to be segregated from field and factory installed
conductors and uninsulated live parts of other circuits
operating at over 150 V to ground so that a minimum
permanent 2 inch (50.8 mm) separation is maintained,
unless the field and factory wiring conductors have
been provided with recognized insulating material
which has an equal or higher voltage rating than the
other circuit involved.
Conditions of acceptability
(File MH19482, Valves and valve terminals):
– These valves are to be factory installed within a suitable
housing or mounted in a guarded and protected loca-
tion to prevent accidental contact in end-use product
since the Impact Test was not performed.
– Theses valves are intended to be energized only from a
suitable NEC Class 2 source of supply not exceeding
30 Vrms (42.4 Vpeak).
– The valve leads/connectors/terminals are intended to
be factory-wired only.
– The suitability of any mating connector must be deter-
mined in the end product.
– These valves are intended to be used in conjunction
with air tubes with following outside dimensions:
