Hardware Installation
Correctly install IOEM and REM system components and peripheral devices to
ensure accurate data collection and reliable operation. First, determine what monitor,
control, alarm and output functions the IOEM and REM expansion modules will
perform. Because system components are wired to IOEM and REM instruments,
it is important to determine where and how components will be installed and con-
figured. Preparing a system schematic (figure 3.1) is helpful.
Figure 3.1
Hardware installation steps (not all steps required for all applications):
Step 1 - install IOEM and REM instrument
Step 2 - ground IOEM and REM
Step 3 - wire power
Step 4 - wire relays - REM only
Step 5 - wire I/Os - IOEM only
Installation and Wiring
Step 6 - wire a network of 2 - 32 instruments, including slave address dip switch
configuration
Step 7 - wire communications hardware

Chapter 4 “Configuring IOEM and REM Channels,”
directions on configuring IOEM and REM expansion modules using AquaManager
PC software.
Tools and supplies needed for hardware installation:
•
Phillips-head screwdriver to remove IOEM and REM front panel to ac-
cess board assembly
•
necessary tools for cutting mounting holes in mounting brackets (rail
mount)
•
electric drill and bits for mounting IOEM and REM (panel or rail) and
for drilling rubber grommets in bulkhead fittings
•
small flat-head screwdriver to terminate wires on the IOEM and REM
board’s pluggable terminal strips
•
wrench to tighten the bulkhead fittings following system component wiring
•
wire strippers
•
contactors may be required for relay wiring; see
contactor wiring
- page
Optional accessories for hardware installation:
•
surface mount hardware (included)
•
rail mount hardware
•
weather shield hardware
•
cabling for network wiring
•
wiring not supplied with components and/or peripheral devices
Step 1 Install IOEM and REM
Select a mounting location and method to mount the IOEM and REM.
Location Considerations
The IOEM and REM must be located:
•
above any level where water damage can occur
•
away from extremely high or low temperature sources
•
away from vibrating surfaces
•
at least two (2) feet (.7 m) from any high voltage conduit
•
away from electromagnetic, radio, AC motor, transformer, or antennas
•
so the front panel can be fully opened and serviced
• so system component wires are run as specified in this manual and ac
-
cording to all local applicable electrical codes.
