EMC/EMI

All electronic equipment can emit, or be sensitive to, induced electromagnetic noise which can be
conducted by the connected wires, or transmitted as electromagnetic fields.     
Electromagnetic noise can cause malfunction or damage to the equipment.
The Series 225 fulfils the relevant EMC standard (refer to specifications) and is therefore CE
labelled.

Note:

 The stated EMC- and safety approvals and other specifications are valid only if the

equipment is installed according to the instructions contained in this manual.
