This device is intended to be used with a Class 2 power source or Class 2 trans
former in accordance with UL1310 or UL1585.
As an alternative, an 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 maxim
um open circuit voltage potential available to the product is not more than
30 V DC and the current is limited to a value not exceeding 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. 3.3 A and be in
stalled in the 30 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, connec
tion in parallel is not permitted.
