Refer to the installation instructions provided by the breaker manufacturer that are included
with the main circuit breaker kit ordered. Main feed termination instructions are outlined
below.

Installing Relays and Dimmers

Single pole relays and dimmers have the same size foot print and install in the same manner.
You may need to field install relays or dimmers into your panel if:
the custom-ordered panel did not ship with them installed
•
you are modifying the physical configuration after installation
•
you are replacing damaged units
•
Relays and dimmers are numbered in the same manner as a branch circuit breaker panel; left
to right, then down. A matching branch circuit breaker must be installed in the same
numbered breaker slot as the related relay output position. i.e. breaker slot #1 should match
output #1.
Note:
If the rack is installed for bottom feed, relay #1 and breaker #1 will be in the
bottom-right corner rather than the top-left corner.
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.
