Introduction 5
0-10V Dimming Control
The 0-10V Dimming Control option card (ERP-FT-LVD) provides
24 outputs for control of 4-wire current-sink, 0-10VDC or
electronic loads.
•
Each of the 24 outputs are rated to control a maximum of
400mA per channel (up to 50 ballasts per channel).
•
Loss of power at the ERP-FT panel controller results in
releasing control levels to full.
For more information, see 0–10V Option Card on page27 .
WARNING: RISK OF DEATH OR INJURY BY ELECTRIC SHOCK! 0–10V wiring
may not be fully isolated from high-voltage AC power. Do not assume that
0–10V wiring is safe to touch, even when run as an NEC Class 2 signal. Test
for AC voltage to ground before terminating any 0–10V control wiring to the
device.
AVERTISSEMENT : RISQUE DE MORT OU DE BLESSURE PAR
ÉLECTROCUTION! Le câblage 0–10V peut ne pas être complètement isolé du
courant alternatif haute tension. Ne supposez jamais que le câblage 0–10V
peut être touché en toute sécurité, même s'il est utilisé avec un signal NEC
de Classe 2. Testez la tension alternative par rapport à la terre avant de
raccorder tout câblage de commande 0–10V à l'appareil.

The Digital Addressable Lighting Interface Control card (ERP-
FT-DALI) controls 24 loops of 64 DALI compatible ballasts in
broadcast mode. Each loop of up to 64 ballasts are linked one
to one with the relay panel circuit for power control.
The DALI ballast must be powered by an external DALI loop
power supply (supplied by others). This supply is connected
externally of the panel. Each DALI loop requires its own power
supply, and possibly more than one power supply depending
on the ballast load.
•
Installation is limited to 64 DALI compatible fluorescent
ballasts per DALI loop.
For more information, see DALI Option Card on page31 .
Note: You cannot assign the same 24 control circuits to both a 0-10V Option Card
and a DALI Option Card. Each group of 24 control circuits may be assigned to a single
low-voltage dimming control option card (0–10 V or DALI) and/or to a Contact Input
Option Card.

6 Relay Panel Feedthrough Installation Manual
Contact Input
The Contact Input card (ERP-FT-CI) provides the ability to
directly control the relays using a momentary or maintained
dry contact input.
For more information, see Contact Input Option Card on
page35 .
Ride-Thru Option
The Ride Thru Option (ERP-FT-RTO) maintains power to the ERP-
FT panel controller for a minimum of 15 seconds in the event of
a brown-out or power loss.
•
The ERP-FT-RTO option card mounts behind the user interface.
For more information, refer to the Ride Thru Option Kit
Installation Guide provided with the option card and available
for free download at etcconnect.com.

Cable Routing and Conduit Access
Echo Relay Panel Feedthrough has removable plates located on top, bottom and both sides to
accommodate conduit fittings for line, load, and feed wiring. Two knockouts, one on each
side of the user interface, are specifically provided for low-voltage (control) wiring.
Note: Class 2 control wiring must be run separately from line, load, and feed wiring.
Note: Remove a plate to punch conduit access as needed for line, load, and control
wiring. It is acceptable to remove the plate permanently if the unit is mounted in
direct contact with an adjacent Feedthrough panel.

1. Remove the front
covers with locking
doors to reveal the
panel interior.
2. Align the panel to the
desired mounting
location and mark all
keyhole locations.
•
Install ERP24-FT up to
two high.
•
Install any number of
ERP24-FTor ERP48-FT
panels side-by-side, in
direct contact, with the
removable plates on the
shared sides removed as
needed.
Allow clearances as
described on page 9 .
3. Set the panel aside.
4. Pre-drill then install the
required mounting
hardware for mounting
the panel using the
previously marked
reference points as a
guide.
•
ERP24-FT requires four
6–8 mm (1/4–3/8in)
bolts or screws, 50–
100mm (2–4in) long and suitable wall plugs
-
Both the surface and mounting hardware must support 23 kg (50 lbs).
-
Expose at least 25 mm (1in) of threads for mounting the panel.
•
ERP48-FT requires six 6–8 mm (1/4–3/8in) bolts or screws, 50–100mm (2–4in) long and
suitable wall plugs.
-
Both the surface and mounting hardware must support 46 kg (100 lbs).
-
Expose at least 25 mm (1in) of threads for mounting the panel.
Mount the Panel
1. Mount the panel to the installed mounting bolts.
2. Tighten the bolts securely.
3. Check for a plumb installation and follow all local code restrictions.

Installation Procedure 15
Rough-in Conduit and Cable
The Echo Relay Panel Feedthrough has removable plates located on top, bottom and both
sides to accommodate conduit fittings for line, load, and control electronics power wiring.
Remove the plates to punch conduit access as required.
1. Install conduit for line, load and control wiring to the panels in the appropriate locations.
See Cable Routing and Conduit Access on page13 .
•
Size conduit appropriately for the specified wire and expected loads at the panel.
Note: It is the installing contractor’s responsibility to comply with all local electrical
codes. For UL 924 emergency installation, secure an emergency power source for
control electronic power and line feeds as required.
2. Install conduit as required for low-voltage control wiring. All low-voltage terminations are
conveniently located behind the user interface of the panel. Two 12.7mm (1/2in)
knockouts are provided for low-voltage control wiring access.
Note: All low-voltage (Class 2) control wiring must be routed separately from high-
voltage (Class 1) wiring.
3. Pull line, load, and control wiring through installed conduit to the panel.
•
Individual line feeds from branch circuit breaker to relays.
•
Individual load wires from the relays to the lighting loads.
•
A dedicated circuit for control electronics power.
4. Pull low-voltage (control) wiring through the conduit to the I/O compartment knockouts.
See Cable Routing and Conduit Access on page13 .
Connect Wiring
Relays - Each relay has staggered output terminals for easy access to line and load connection.
A Phillips screwdriver and wire strippers are required for relay line and load terminations.
Control processor electronics AC input - A discrete circuit is required to power the control
processor; refer to Cable Specification for Data and Control on page 12 for details.
Terminations require only a precision flatblade screwdriver and wire strippers.
I/O terminations - All low-voltage control terminations are conveniently located behind the
user interface. Fold the user interface panel down to reveal termination points for DMX,
Network, Contact Input, 0-10V Control, and DALI control.
Connect Line and Load Wiring
ERP-FT is shipped standard with either 12, 24, or 48 relays installed. Depending on customer
requirements the relay type and quantities may vary for custom orders. Three relay types are
available for customer convenience, reference Relay Specification on page 10 for specification.

16 Relay Panel Feedthrough Installation Manual
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
