Notes about

This device is intended to be used with a Class 2
power source in accordance with UL1310.
As an alternative an LV/C (Limited Voltage/Current)
power source with the following properties can be
used:
This device shall be used with a suitable isolating
source in conjunction with a fuse in accordance
to UL248. The fuse shall be rated max. 3.3 A and
be installed in the max. 30 V DC power supply to
the device in order to limit the available current to
comply with the UL requirements
possibly lower connection ratings for your device
(refer to the technical data). A maximum power of
100 VA according to Tab. 32.1 (UL508) must not
be exceeded.
1) Note on the scope of the UL approval: the devices have been
tested as per the requirements of UL508 and CSA/ C22.2 no. 14
(protection against electric shock and fire).
