Overview
Note: The Power Control Processor Mk2 Replacement Kit is for use with panels where a
Power Control Processor Mk2 is already installed.
The Power Control Processor Mk2 (PCP-Mk2)
is used in Echo Relay Panel Mains Feed and
Elaho Relay Panel Mains Feed (ERP Mains
Feed), Echo Relay Panel Feedthrough and
Elaho Relay Panel Feedthrough (ERP
Feedthrough), and Sensor IQ systems. These
systems support field-replacement of the
PCP-Mk2 and the Termination Board to which
it connects. To replace the PCP-Mk2,
complete all of the procedures:
1. Replace the Power Control Processor
Mk2
2. Configure the Processor on page4
a. Access the Factory Menu on page4
b. Power Calibration on page4
If you are replacing the Termination Board,
you only need to complete the Power
Calibration on page4 .

WARNING: RISK OF DEATH BY ELECTRIC SHOCK! Failure to disconnect all
power to the panel before working inside could result in serious injury or death.
AVERTISSEMENT : RISQUE DE MORT PAR ÉLECTROCUTION! Travailler à
l’intérieur du panneau sans avoir déconnecté le courant peut entrainer des
blessures graves, voire mortelles.
De-energize main feed to the panel and follow appropriate Lockout/Tagout
procedures as mandated by NFPA 70E. It is important to note that electrical
equipment such as relay panels can present an arc flash hazard if improperly
serviced. This is due to the high amounts of short-circuit current available on the
electrical supply to this equipment. Any work must comply with OSHA Safe
Working Practices.

Move a RideThru Option Card - ERP Mains Feed, ERPFeedthrough,
or EchoDIN
If your ERP Mains Feed, ERP-FT, or EchoDINpanel has a RideThru Option Card, follow the
instructions below to move it to the new PCP-Mk2.
1. Disconnect the red-and-black harness from the old user interface's two-pin "ride thru"
header.
2. Remove the three screws securing the RideThru Option Card to the old user interface.
• Set the three screws aside for reinstallation.
• Keep any spacers that were installed with these screws. You will need a total of three
spacers to install the RideThru Option Card on the new user interface. Two spare spacers
(ETCpart number HW9444) are included in the Power Control Processor Mk2
Replacement Kit.
3. Secure the RideThru Option card to the new user interface with the three screws you
removed above, placing one spacer on each screw between the user interface and the
RideThru Option Card bracket.
4. Connect the free end of the red-and-black harness on the RideThru Option Card to the two-
pin "ride thru" header on the new user interface.
Connect the Wiring to the PCP-Mk2
CAUTION: If you disconnected the six-color power wiring harness (7123B7021)
from the termination board, ensure that the connector is aligned pin-for-pin
with the header on the termination board when you reinstall it. If you misalign
the pins you may damage the equipment.
1. Install the gray ribbon cable to the header on the new user interface and secure it with the
retainer clip (included, ETCpart number HW7519).
2. Install the free end of the six-color power wiring harness (7123B7021) to the new user
interface at J3 "POWER".
• If you disconnected this harness from the termination board, ensure that the connector
is aligned pin-for-pin with the header on the termination board when you reinstall it.
3. ERPMains Feed and Sensor IQonly:Install the free end of the five-color power sense wiring
harness (7123B7001)to the new user interface at J5 "DIGITALPOT".
4. ERPMains Feed only:Install the free end of the three-color wiring harness (7123B7004)to
the new user interface at J6 "RELAYBUS".
5. Connect the network patch cable to the new user interface.
