I am looking for help rationalizing when a product must be evaluated to the
LVD.
This is for a product my company is considering namebranding.
I would like to see the product evaluated to EN60950 but the vendor is arguing
that due to the 24VDC, low voltage rating the product does not need to be
formally evaluated to an European safety standard to claim the CE mark.  The
product does meet UL508.
 
Background -  The product is  a communication gateway with the following ports:

*       DC power in put 24VDC ~ 10W (not internally fused)
*       Ethernet, Cat5 RJ45 twisted pair  LAN/WAN interface
*       RS485 multipoint subnetwork (Modbus, cable up to ~ 4K')
*       Proprietary twisted pair multipoint network similar to RS485 (cable up 
to
10K')
*       RS232 port for connecting to external modem like devices
*       USB slave - temporary programming port
*       Modem Interface - optional (not found on all models)

In my view the Modem interface is very hazardous and so the product should be
formally evaluated.
Since the modem interface is a USA version perhaps this model could be
excluded from having a CE mark.
Anything else stand out as requiring evaluation to EN60950?
 
Also I remember reading that this voltage limit exception topic is under
review.
 
Thanks
