Reserve Power/Ac Wiring For Three Or More Cabinets (Floor Mount); Step 7: Install Processor And Universal Pcbs - Toshiba Strara CTX Series Installation And Maintenance Manual

Reserve Power/AC Wiring for Three or More Cabinets (Floor
Mount)
To connect reserve power to floor-mounted systems with three or more cabinets
See Fig 3-13 and follow these steps:
1. Make sure that the Conduit Connection Box is installed on the bottom base cabinet (see
3-20). The box can be installed by the regular system installer.
2. Have a licensed electrician install conduit and battery cabling to the Conduit Connection Box per
local electrical codes. The remaining steps in this procedure can be performed by the regular
system installer (see
3. Install the Battery Distribution Box on the second cabinet (the cabinet directly above the bottom
cabinet), see Figure
4. Plug the two Conduit Connection Box cables (coming from the left side of the BCCB box) into the
Battery Distribution Box (BBDB).
Important! The cabinets must be connected to the (live) AC power source, and the power supply On/
Off switches set to On prior to the final step of connecting the reserve power batteries to
the power supplies via the BATT +/- receptacle. If the batteries are connected after AC
power is lost, reserve power will not function.
5. Connect cables from the (BBDB) Battery Distribution Box to the BATT +/- receptacle of
individual power supplies. BBTC2A-2M cables come with each BBDB distribution box.
6. To test reserve power operation, turn off the system AC power circuit breaker with power supply
On/Off switches in the On position. The system should continue to operate without interruption.
AC/DC wiring and conduit must be installed by a licensed electrician per local electrical code
Note
(conduit trade size is 1.27cm or 1/2 inch).
