Overview
The Contact Input Option Card (ERP-CI) provides the
ability to directly control the relays of the Echo Relay
Panel using a momentary or maintained dry contact
input.
Installation
WARNING:
power to the panel before working inside could result in serious injury or
death.
AVERTISSEMENT :
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.
Note:
control terminations are complete to reduce the likelihood of damage to the option
card.
1. Turn off power to the relay panel.
2. Align the ERP-CI option card to the mounting studs located at the base of the rack to the
right of the relay panel termination I/O board.
