3.5.2 Base Unit Wiring
Figure 9 shows the TS4000H terminal block connectors TB1, TB2, and TB3 that hold the wiring
that connects the TS4000H to local alarms and control room equipment. You must remove the
cover from the TS4000H 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 TS4000H to DC Ground on the power supply first,
then the Modbus and Analog device wiring connections. The +24 VDC signal on the power
supply must be connected last. Power to the TS4000H must remain
OFF
until all wiring is
completed and the start-up readiness checklist has been verified; refer to Section 3.6.1.

CAUTION:
Contact with PCB components should be avoided to prevent damage by static
electricity. All wire connections are made to the terminal blocks. The following
procedure is for attaching wiring to connectors in the TS4000H terminal blocks
TB1, TB2, and TB3.
