ATI A15/66 Residual Sulfite Monitor

O&M Manual

Rev-W (8/10)

ELECTRICAL CONNECTIONS

AC power must be connected to both the monitor and the chemistry module. Refer to Figure 5 below for

the proper connections. A power cord is supplied with each unit for AC connection and a 6- conductor

interconnect cable (20 ft.) is supplied for connection of the chemistry module to the monitor. Note that the

terminal blocks at the rear of the monitor unplug for wiring convenience. Figure 6 provides the

interconnection wiring diagram between the chemistry module and the monitor. The chemistry module

can be located up to 100 feet from the monitor provided that connection is made with a single length of

#31-0037 cable. Cable must be ordered separately.
