Pulsafeeder Pulsar ECA NEMA4X - Manual (Page 14)

6. INSTALLATION AND WIRING
6.1 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 .
6.2 Installation Notes
• 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.
• 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. In accordance with any applicable codes provide sealed entries and
conduit drains near the point of entry as required.
• All applicable codes and regulations should be adhered to in the installation and wiring
of the ECA.
The safety of any system incorporating the ECA is the responsibility of the assembler
of the system.
6.3 Installation guidelines for EMC compliance
• The cover must be installed properly.
• Shielded cables used for analog inputs and outputs
• Proper Earth grounding
• Insure Power mains are properly filtered for isolation from line transients, lightning
strikes, or other electrical noise sources.
Failure to observe the guidelines above may lead to erratic and possibly unsafe operating
conditions.
Review the Safety section prior to installing the ECA. It contains important information
required to properly install and operate the ECA in industrial environments.
