Contacting ETC about equipment problems
If you are having difficulties, your most convenient resources are the references provided in this
manual. To search more widely try the ETC web site at
etcconnect.com . If none of these resources is
sufficient, contact ETC technical services directly at one of the offices listed on
page 1
.
Emergency service is available from all ETC offices outside of normal business hours. When calling for
assistance, please have the following information handy:
• Your location and job name.
• Model of relay or breaker panel(s).
• Type of relays and breakers used including model number and quantity.
• Other components in your system including dimmers, switch gear, quantity and type of wall
stations, etc.
• DMX and/or sACN control source used for system-wide control, if any.
• Related system problems or equipment failure.
Maintenance
Vacuum the Interior
1: Remove power from the panel.
2: Remove any doors, top, and bottom front panels from the rack.
3: Vacuum the dust from the interior of the unit. If needed, use canned air to blow dust from the
relay or breaker panels.
4: Reinstall the front panels and door before applying power to the unit.
Changing Fuses
The Echo Relay Panel Mains Feed features internal fuses on the relay cards to protect the relay in the
event of a high current short circuit. Most faults should cause the associated circuit breaker to trip;
however, very high current direct shorts may cause fuse failure also.
Two spare fuses are included inside the panel. The fuse is a 30A SC–30 and is available from ETC with
part number F334. Replace the fuse with the same type only.
WARNING:
RISK OF DEATH BY ELECTRIC SHOCK! Failure to disconnect all power to the
panel before working inside the panel could result in serious injury or death.
De-energize main feed to the panel and follow appropriate Lockout/Tagout
procedures as described in NFPA Standard 70E. It is important to note that
electrical equipment such as relay and breaker panels can present an arc flash
safety hazard if improperly serviced. This is due to available large short circuit
currents on the feeders of the equipment. Any work on energized equipment
must comply with OSHA Electrical Safe Working Practices.
