74 S8100 Installation and Upgrades
November 2003
Floor grounds are those grounds on each floor of a high-rise building that are suitable for connection to
the ground terminal in the riser closet and to the cabinet’s single-point ground terminal. Approved floor
grounds may include:
• Building steel
• The grounding conductor for the secondary side of the power transformer feeding the floor
• Metallic water pipes
• Power-feed metallic conduit supplying panel boards on the floor
• A grounding point specifically provided in the building for the purpose
Uninterruptible power supply
A recommended uninterruptible power supply (UPS) may be used for power holdover. The type of UPS
depends on the holdover requirements. Total holdover capacity varies depending on the UPS. The UPS
must provide surge protection for the G600 cabinet.
CAUTION:
The major-alarm contacts should only be connected to a UPS that can indicate its backup
power status. For most non-Avaya UPSs, you should not use the major external device
leads. Using these leads for anything else could cause an SPE download.
1 Connect the UPS to an electrical outlet capable of handling the power requirements of the
cabinets:
a 100 VAC, 4.5 Amps
b 120 VAC, 3.8 Amps
c 200 VAC, 2.3 Amps
d 220 to 240 VAC, 2.0 Amps
2 Ensure that the cabinet is connected to an “unswitched” or “always-on” electrical outlet on the
UPS.
3 For an Avaya UPS, connect and administer the UPS. See Connect external alarms and auxiliary
connections on page 113.
NOTE:
If an Avaya UPS is wired as recommended, holdover time for each power outage is 1
minute before an automatic shutdown. UPS may handle any subsequent power outage
based on its total battery capacity.
Cabinet’s power switch
!
DANGER:
The latch acts as the DC power switch and only removes DC power from the cabinet,
not AC power. To remove AC power, pull the AC power cord from the appliance
inlet. See Figure 9, G600 650A power supply,
on page 75.
