• INSTALLATION AND SETTING
•B FOR INSTALLATION, ISOLAT TH SUPPLY.
•Remove the P50 FR from the packaging.
•Lift the raised part of the side clip and slide towards the rear of the
housing to remove. Carry this out on both sides.
•Insert the P50 FR in to the panel cut-out and fit the side clips back
on to the housing.
•Slide the clips towards the front of the unit until they come in to
contact with the reverse side of the panel. The unit is now secured
in place.
•Connect the wires to the rear terminals as required following the
diagram shown on the next page and for the relevant model shown.
•nsure the Auxiliary supply voltage to be connected to terminals 1
and 8 matches the rating of the product.
Setting up
•The unit should be set according to the requirements of the
application.
Applying power
•Apply power and the green “Power on” ➍ L D will illuminate.
•Assuming no fault present, the output relay(s) will remain in the de-
energised state.
•If a fault is detected, the red L D ➎ will remain constantly lit for the
set delay “t”. If the unit trips, the red L D will then flash.
Fault simulation (Test mode)
• The unit can be placed into a fault condition by pressing the “Test”
button ➌ on the front of the unit. The output relay(s) will energise.
• Press the “Reset” button ➏ on the front to reset the unit. The
output relay(s) revert back to the de-energised state.
• The unit can also be reset by interrupting the power supply
• To satisfy regulations, it is recommended that the device be tested
periodically to ensure correct operation.
Troubleshooting
• If the unit fails to operate correctly check that all wiring and
connections are good.
