– 18U Cabinet Cable Knockouts
To prevent water entering the cabinets, seal unused knockouts and any top cable entries. Where possible, use bottom
cable entry with cables going down 100 mm below the cabinet before rising.
Mains Wiring
The BOWS needs to be supplied with a current-limited mains feed (e.g., via a circuit breaker) direct from a main
switchboard (refer AS 3000).
The General Purpose Outlet (GPO) must be wired by a suitably qualified electrician.
IMPORTANT: The factory-fitted earth loom under the GPO mounting block must be wired to the earth terminal of the
GPO in order to correctly earth the BOWS cabinet.
Battery Wiring
The 8U cabinet has space for a pair of 12V 17Ah batteries, the 18U cabinet has space for a pair of 12V 75Ah batteries.
The BOWS panels are supplied with a red battery lead for joining the neg(-) terminal on the 1st battery to the pos(+) on
the 2
nd
battery, and the screws, washers and nuts required for attaching the leads to the batteries.
Figure 4 - Battery Wiring
Factory Wiring
The PSU 24V output is wired to the T-Gen2 +24V terminals and the PSU Charger Flt- signal is wired to the A/I/E- input.
The default BOWS configuration for T-Gen2 sets the A/I/E- input as External PSU Fault, allowing a PSU fault to signal
via the T-Gen2.
The User Interface and microphone are connected to the T-Gen2 QBus connector J32 and PA MIC Connector J9
respectively.
T-Gen2 Field Wiring
Refer to the T-Gen2 Installation and Operating Instructions (LT0667) included with the BOWS for details on connecting
field wiring to the T-Gen2 and how to use the OLED display on the T-Gen2.
