2 Important Safety Precautions
PROJOY assumes no responsibility for any loss, in particular for circuit damage, resulting from any violation of the specifica-
tions recommended and referred to in this specification. PROJOY assumes no responsibility for the damage of the product
caused by the maintenance, improper use, wrong installation or wrong system design of the product by non-designated
personnel.
3 Introduction
2.1 Disclaimer:
1) PEFS is an electrical product that should be installed by a suitable person who meets local regulations.
2) When modifying and existing installation, isolate the inverter from the PV array by turning OFF the DC isolator / switch
disconnect or turn OFF the inverter and the AC switch.
3) Incorrect connections to the PEFS-24V-CN may cause failure.
2.2 Safety instructions:
If the inverter and pv module connectors are not compatible with PEFS connectors, forced connections are unsafe and may
cause operational problems.
For the mechanical compatibility of the module / converter and PEFS, use the same connectors from the same manufacturer
on both the PEFS and modules, or obtain verification that the connectors to be used are compatible.

3) The installation modes of PEFS-24V-CN are divided into the following two situations.
Control Box Include Power Supply (Take PEFS-24V-C60 as an example)
a) Align the round hole of the L-shaped calsp with the round hole of the box and fix them with screws.
b) Mount the control box to the appropriate location through the gourd-shaped hole.

6 Trouble Shooting
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 (-)
