See the 7360 ISAM FX Safety Manual for more information.
6.3 Shelf grounding connection
This section provides the 7360 ISAM FX-16 shelf grounding cable types, cable
routing, and connection information.
Observe the following safety notes.
6.3.1 Grounding cable type
As shown in Figure 35, the 7360 ISAM FX-16 includes two grounding cable
connectors. Each ground lug is a 4 AWG, 1/4 in. stud with 1 in. hole spacing, single
crimp, peep, copper, UL and CSA recognized dual-hole lug. The preferred cable is
4 AWG, green with a yellow stripe. Other types and sizes of wire and lugs can also
be used provided they meet the requirements of Article 250 of the NEC.
Caution — Risk of EMC disturbance when MDF cables are not
shielded.
When MDF cables have no or insufficient shielding, the xDSL
and POTS signals carried could suffer from EMC disturbance,
certainly when mixing different xDSL signal types (for example,
xDSL over POTS with xDSL).
To comply with EMC, observe the following:
• Apply shielded LINE and POTS cables between the MDF
and the 7356 ISAM FTTB (Nokia always provides shielded
cables).
• Connect, if possible, the shielding of each MDF cable to
ground at MDF end.
Danger 1 — Rack or frame must be suitably connected to the
office grounding network in accordance with Article 250 of the
national electrical code (NEC) to ensure UL and CSA
compliance. If outside the United States, ground per local
electrical codes and practices.
Danger 2 — Possible risk of personal injury or damage to
equipment due to inaccurate or faulty ground cabling.
Inaccurate grounding connection can cause electric shock or
equipment damage when the rack power is switched on.
