Overview
An existing SmartSwitch can be converted to house the Power Control Processor used in Echo Relay Panel
Feedthrough. This processor allows additional functionality such as DALI control, contact input control,
0-10V control, and Ethernet network connectivity. This guide details the installation of this retrofit kit into
both the 24- and 48-position SmartSwitch.
Adding a retrofit kit to a SmartSwitch Relay Panel changes the panel model. With the retrofit kit installed, the
panel becomes an Echo Relay Panel Feedthrough (ERP24-FT or ERP48-FT).
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 D'ELECTROCUTION! 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.
