The following safety precautions apply:
22.3 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:
Danger 1 — Before working on the power supply unit, verify
whether it is live.
If the power supply is live, which can deliver −48 Vdc, you must
use an insulated tool kit. See 7360 ISAM FX Safety Manual for
more information about working with live components.
Danger 2 — Avoid risk of electric shock.
Always wear protective gloves and footwear for all handling
tasks.
Carefully follow the instructions.
Warning 1 — Before connecting to the power, verify the
specifications of all equipped fan units to ensure that the
correct voltage will be supplied (−48 Vdc) to these units.
Warning 2 — Before power is supplied, all fasteners requiring
a specific torque must be tightened moderately before final
tightening with a torque wrench or driver.
When power is supplied, tighten fasteners with insulated tools,
according to the specified torque.
Warning 3 — The 7360 ISAM WM power card does not
support hot insertion.
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.
