INSTALLATION
1.
The MPA-48 analyzer should be located to allow convenient access for an operator to read and
technician to install and maintain. A rear rail mounting kit is available for the standard enclosure
(see Drawing IIG07N110). This mounting kit is design for a standard 2” handrail but can be
adapted to square or angle handrails as well.
DO NOT! Locate the analyzer where it is likely to be
damaged during unrelated or other periodic maintenance such
as pressure washing catwalks.
2.
Mount the sensor in the desired location. InsiteIG can supply a sensor handrail mounting kit that
easily mounts to most handrails and slide locks the sensor into place with out the use of tools.
(See drawings IIG02N004, IIG02N005, IIG03N004 and IIG03N005). Again, this sensor mounting
kit is design for a standard 2” handrail but can be adapted to square or angle handrails as well.
DO NOT install a pH/ORP holder (Model 50) without a pH
cartridge (Model 51) or an ORP cartridge (Model 52) installed
and properly seated in the pH/ORP holder. Installing a pH/ORP
holder without a pH or an ORP cartridge will void the warranty.
WARNING! – Before opening analyzer
cover; switch off the analyzer line power at the circuit
breaker to avoid risk of shock. Line power is present
on terminals even when analyzer is switched off.
WARNING! – Circuit breaker meeting IEC-
947-3 must be on line supply, in close proximity to
equipment and shall be marked as the disconnecting
device for the equipment.
3.
Open the enclosure of the Process Analyzer. Pass all connection cables through glands or ½”
conduit in the bottom of the enclosure (gland and conduit are not supplied). The sensor input
connections are made to terminal blocks TB1 through TB4 (labeled SENSOR 1 through 4) on the
standard unit (see drawing IIG07R111) and TB2 of the daughter boards for sensor 5 through 8.
The four wires are color coded and there is a cable shield. Connect the RED wire to the terminal
labeled “RED”. Connect the GREEN wire to the terminal labeled “GRN”. Connect the WHITE
wire to the terminal labeled “WHT”. Connect the BLACK wire to the terminal labeled “BLK”.
Connect the cable SHIELD to the terminal labeled “SHLD”. The analog outputs are available
on the terminal block labeled TB8 & TB9 and the relay outputs are available on the terminal
block labeled TB5.
