3.5.2 Base Unit Wiring
Figure 9 shows the TS4000 terminal block connectors TB1, TB2, and TB3 that hold the wiring
that connects the TS4000 to local alarms and control room equipment. You must remove the
cover from the TS4000 Base Unit to access these connectors. The inside cover includes a label
listing the function of each connector location.
To ensure safety, install cabling from the TS4000 to DC Ground on the power supply first, then
the MODBUS and Analog device wiring connections. The +24VDC signal on the power supply
must be connected last. Power to the TS4000 must remain
OFF
until all wiring is completed
and the start-up readiness checklist has been verified; refer to Section 3.6.1.
