Statement
An external Surge Protection Device (SPD) is to be used at the AC power service entrance.
GR-1089 Section 4
Only copper cables are to be used for grounding purposes.
GR-1089 Section 9
The grounding conductor AWG size should match the size of the power cable AWG.
Bare conductors must be coated with antioxidant before crimp connections are made.

WARNING:
BTI7800 Series equipment is only suitable for connection to
intrabuilding wiring.
WARNING:
BTI7800 Series equipment is suitable for installation in a common
bonding network.
WARNING:
Do not install power cabling on an electrically live system. Ensure
that all power is removed from the shelf before continuing with this procedure.
Actual wire gauge should be determined based on local engineering standards
and practices.
WARNING:
Before connecting power to the BTI7800 Series chassis, remove
the fuses or circuit breakers from both the A and B sides of the battery
distribution bay (BDB) and power distribution panel (PDP). Failure to do so
can cause serious injury or death.
WARNING:
Touching electrical connectors or other exposed electrical circuitry
inside the BTI7800 Series chassis or other provisioned circuit packs when
they are energized can cause serious injury or death.
The following table lists some important regulatory requirements for NEBS (Network
Equipment-Building System) that you must follow when installing BTI7800 equipment.
