  • Entry
  • Associated product(s)
Effective immediately, the RFID standard cables for products of the SIMATIC RF and SIMATIC MV series will be converted from type CMG to type CM with regard to their tray fire propagation characteristics. Any cables already installed are not affected by this conversion. Existing inventory will be sold. The cable labeling is binding.

Effective immediately, the RFID standard cables for products of the SIMATIC RF and SIMATIC MV series will be converted from type CMG to type CM with regard to their tray fire propagation characteristics. This conversion includes all cables for power supply and serial data communication. The old approval according to CMG and the new approval according to CM are each certified by the nationally recognized ETL Testing Laboratories in the United States.

 

Any cables already installed are still approved according to CMG and are not affected by this change.

Existing inventory will be sold. The cable labeling specifies whether the cable has been approved according to CMG or CM.

Labeling of an old cable of the type CMG:

 


 


 

Labeling of a new cable of the type CM:

 


 


 

Both approvals (CM and CMG) relate to the fire behavior of general purpose cables that are installed in cable trays in buildings. The fire behavior is tested with the tray flame test for vertical installation of the cables according to UL 1685 (Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables). Both types of approval (CM and CMG) are permitted in the United States as well as in Canada for use in cable trays.

• Type CM: UL 1685 Sec.4 Vertical Tray Flame Test (UL method)

• Type CMG: UL 1685 Sec.12 FT4/IEEE 1202 Flame Test (CSA method)

 

The remaining technical properties of the cables remain the same.
