Installation Guide
Waterproof terminal - Insert the seal case to the AMP terminal and connect one end
to a PEFS-PL DC output connector in the series installation. If only one PEFS-PL is
used, this section still needs to be sealed over the AMP terminal to prevent leakage.
OPERATION
Upon correct mounting and connection of the PEFS-PL to the solar panels and the Emergency Shutdown Switch;
and the turning ON of the mains supply, the PEFS-PL will be operational.
1. Automatic emergency shutdown
If PEFS-PL's onboard temperature sensors detect an ambient temperature in excess of 85°C, PEFS-PL will
instigate an automatic rapid shutdown thereby disabling the PV module’s output. Should the detected
temperature then drop back to below 85°C, the PEFS-PL will re-engage the PV module’s output.
2. Manual shutdown
Upon the user operating the red push button switch located in the Emergency Switch Enclosure the PEFS-PL
performs a Rapid Shutdown, disabling the PV array output.
3. AC Supply Cut-Off Shutdown
Should there be a necessity by the emergency services for local or area utility grid shutdown, disconnection of
the external AC supply, by whatever means, will cause the PEFS-PL to perform a Rapid Shutdown disabling the PV
array output.
