Extracts )* from the UL report:
Only for connection to a 24 Vdc 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 Vdc 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 Vdc 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.

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.
– 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
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):
– The need for a suitable enclosure is to be determined in
the end-use equipment.
– The valve terminals are intended to be factory-wired
only.
– The suitability of any mating electrical connector must
be determined in the end product.
– Torque tests were performed according to ISO 16030,
Pneumatic Fluid Power – Connections – Ports and Stud
Ends, first Edition dated December 15, 2001, Table 3.
Values are specified below.
– Impact Tests on the thermoplastic fluid-confining parts
were not conducted. In the end-product equipment the
valve shall be suitably enclosed, or mounted in a loca-
tion where it is guarded or protected from impact.
– These valves are intended to be used in conjunction
with air tubes with following outside dimensions:
