Possible Solution
Check area utility operational
Check mains ON
Check mains fuse
Check mains voltage between L&N marked terminals
Check 24VDC between + & - marked terminals
Turn red actuator anti-clockwise to release button
Check 24VDC between switch out terminal & PSU – marked terminal
Check 24VDC between terminals of remote AMP
Superseal connector (pin 1 +24VDC\pin 2 0VDC)
Check all PV to PEFS-24V-CN input connections
Check PV array Positive (+) goes to PEFS-24V-CN
Positive (+) and PV array Negative (-) goes to PEFS-PC Negative (-)
Replace PEFS-24V-CN
Check PEFS-24V-CN output connections
Check DC inputs to isolator
Turn DC Isolator ON
Check all PV array Positive (+) go to PEFS-PC
Positive (+) and PV array Negative (-) goes to PEFS-PC Negative (-)
