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 exceed-
ing 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
Note
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:
– These valves are only intended for use in indoor-dry
locations only.
– These valves are to be factory-wired only.
– The suitability of the factory-wiring, including mating
connectors, for secureness, and grounding of dead-me-
tal, shall be determined in the end-product.
– These valves are intended for use in an ultimate electri-
cal enclosure, and the need for an electrical enclosure
for the valves shall be determined in the end product
application.
– These valves are intended for use in a suitable enclos-
ure or mounted in a guarded and protected location
where the valve body will be protected against impact.
– The suitability of the grounding/bonding connection
shall be evaluated in the end product application.
– The suitability of the fluid connections to these valves,
with respect to securement and leakage, are to be de-
termined in the end-product application.
– These valves are intended to be used in conjunction
with air-tubes with the following outside dimensions:
