Rice Lake DWM-IV Digital Weighmeter Model 5 - Manual (Page 7)

3.0 Setup
Set up of the Model 5 requires that the unit be provided with power via the TB1
connector and connected to the load cell via the TB3 connector. The optional connector,
TB2, is used if a serial printer/computer is supplied.
3.1 Power Connection
Refer to the Model 5 circuit board drawing in Section 8.0 BOARD LAYOUT
to locate the power connector TB1, the RS232 connector TB2, and the load cell
connector TB3. Remove the back panel by unscrewing the six screws around the
perimeter. Push the wall transformer cable through the rightmost strain relief,
SR1. Push the load cell cable through the leftmost strain relief, SR3. Using the
supplied three position terminal block, attach the three conductor power supply
cable wires using a small, flat-blade screwdriver according to the following color
codes:
Wall Transformer
P/N AA-091AG
TB1
Wall Transformer
P/N 48A-9-1000
TB1
BROWN +IN RED +IN
GREEN GND WHITE GND
BLUE -IN BLACK -IN
Ensure that the Green or White wire from the wall transformer is always connected
to the GND terminal as this connection is the safety earth conductor. The unit
becomes grounded or earthed by plugging the wall transformer into a properly
wired three terminal wall receptacle. Never defeat the ground connection in the
interest of safety and noise rejection. Insert the power terminal onto TB1 of the
Model 5 circuit board.
