JOSLYN® JSPT M INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Pre-Installation Checklist ✓Confirm that the voltage(s) and service configuration shown on the JSP
product label are consistent with the voltage and service configuration of
the facility. A model number is on the right side of the JSP unit. Each model
number corresponds to the configurations printed in Table 1:
Example of a SPD model number: JSP160-3Y208-F
1These are the only voltages available on the 60, 80, and 100kA systems.
NOTES:
• xxx denotes surge rating per phase (60, 80, 100, 120, 160, 200, 240, 300, 400)
• The power system operation frequency is between 47–63Hz.
Confirm that the environmental conditions are consistent with the
following ranges:
• Ambient Temperatures: Between -40° and +158°F (-40º to 70º C).
• Relative Humidity: Between 5% and 95% non-condensing.
• Altitude: Less than 13,000 feet (4000 m).
