SYSTEM INSTALLATION
System Evaluation
Important!
One of the most important steps in the installation of any RLM takes
place prior to any equipment installation. To ensure that the correct RLM is being purchased
for an application, a site survey should be completed, listing all the fuel dispensing related
equipment.
The survey should include:
C
Model numbers of both dispenser and DBox
C
Manufacturer of equipment
C
Number of dispensers
C
A simple drawing describing the station layout
System Warnings
Safety hazards are inherent with all electrical equipment. Standard precautions must be taken at all times during
installation and operation of the RLM systems. In addition to normal electrical precautions, the following points
should be noted during installation.
C
Installation must comply with the National Electrical Code, as well as Federal, State/Provincial, Local,
and all applicable codes.
C
High voltages are present in the RLM components, as well as the equipment to which it is attaching. To
prevent personal injury or equipment damage, disconnect all power before proceeding with installation.
C
RLM equipment must be installed in nonhazardous areas. The main box must be protected from severe
vibration, extreme temperatures and excessive humidity.
C
All equipment connected to the RLM must be UL-approved and mounted in a non-hazardous location.
Standard RS232 or RS485 connections must be used.
C
The RLM is intended for use with other devices, such as tank monitors, which determine whether leaks
exist at a site. The RLM device cannot determine if product leaks are present.
