4. INSTALLATION
4.1 Location
The site selected for the installation of your ECA is largely dependent on that of the PULSAR
metering pump. Please review the PULSAR Installation Operation Maintenance Instruction Manual
(current version) provided with your PULSAR metering pump. It details system related issues that
are important to proper operation of the PULSAR metering pump. Be mindful of the following ECA
related issues when selecting a site. Avoid locations where the ECA would be subjected to extreme
cold or heat. Note the warning statement. The installation of this device must comply with national,
state and local codes.
A VOID LOCATIONS WHERE THE ECA WOULD BE SUBJECTED TO EXTREME COLD OR HEAT
[ LESS THAN -18° C ELSIUS (0° F AHRENHEIT ) OR GREATER THAN 40° C ELSIUS (104°
F AHRENHEIT )] OR DIRECT SUNLIGHT . F AILURE TO OBSERVE THIS WARNING COULD
DAMAGE THE ECA AND VOID ITS WARRANTY .
4.2 Installation Notes
1. The ECA is a microprocessor-based controller that uses static sensitive CMOS components. Do
not make any electrical connections (high or low voltage) without adequately grounding the ECA
and the worker to eliminate any electrostatic charge between the two. A conductive wrist strap
worn by the worker and attached to the ECA enclosure is adequate to satisfy this requirement.
2. Conduit connections can carry fluids and vapors into the ECA causing damage and void the
warranty. Care should be taken when installing conduit to protect against fluid/vapor entry. If
necessary, provide sealed entries or conduit drains near the point of entry.
3. All applicable codes and regulations should be adhered to in the installation and wiring of the
ECA, especially if installed in a hazardous environment.

Review the Safety section prior to installing the ECA. It contains important information required to
properly install and operate the ECA in industrial environments.
