Option Cards Overview
Option cards are available for field installation into the Relay Panel Mains Feed. Each option
adds another level of features and functions to the panel and the installation.
0–10 V Dimming Control
The 0–10 V Dimming Control option card (ERP-LVD) provides 24
outputs for control of 4-wire current-sink, 0-10 VDC
fluorescent 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 Relay Panel Mains Feed controller results
in releasing control levels to full.
•
The ERP-LVD option card installs by card edge connector to
the left side of the I/O termination board.
For more information, see 0–10V Option Card on page37 .
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-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 ERP. 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.
•
The ERP-DALI Control card installs by card edge connector to the
left side of the I/O termination board.
For more information, see DALI Option Card on page 40 .
Note: A single, 24-position Echo Relay Panel Mains Feed supports the use of either
the 0–10V Dimming Control option card (ERP-LVD) or the DALI Control option card
(ERP-DALI), but not both in the same panel.

Contact Input
The Contact Input card (ERP-CI) provides the ability to directly
control the relays using a momentary or maintained dry contact
input.
•
The ERP-CI card installs by card edge connector to the right side
of the I/O termination board.
For more information, see Contact Input Option Card on page43 .
Ride-Thru Option
The Ride Thru Option (ERP-RTO) maintains power to the Relay Panel
Mains Feed controller for a minimum of 15 seconds in the event of a
brown-out or power loss.
•
The ERP-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 from etcconnect.com.

11 Relay Panel Mains Feed Installation Manual
Chapter 1
Prepare for Installation
Inspect the Shipment
Before you begin installation, check your shipment and confirm it arrived complete and
undamaged.
1. Check the packaging for physical damage.
•
Document any damage found before opening in case of damage to equipment.
2. Inspect the order for completeness.
•
Check the box contents received against the packing list to ensure your order is received
complete.
•
If you discover a problem with the contents of the shipment, contact the Systems Group.
See Help from ETC Technical Services on page10 for contact information.
Unpack Panel
For best results, follow these instructions when unpacking the panel from the box.
1. Lay the box flat, top side up on a floor or flat horizontal surface. The top side of the box is
labeled for your convenience.
2. Lift and remove the box lid. A standard model Relay Panel Mains Feed ships from the
factory, pre-wired with low-voltage relay control. As you remove the Relay Panel from the
shipping carton, confirm the following items are included:
•
A door, wrapped separately but packaged with the panel. The door will appear as a
separate line item on the sales order but ships in the same box as the main panel. Check
that the door is the correct model as ordered.
•
The relay panel with interiors (relay compartment and breaker compartment) and
removable covers.
•
The quantity and type of relays and breakers ordered
•
DMX Preparation kit
•
This installation manual
Note: All accessory options and option cards are packaged separately.
Note: It is recommended to perform the next step with at least two people as the
panel may be awkward and heavy to remove from the packaging.
3. To lift the panel from the packaging, one person lifts from the top side of the enclosure,
indicated with an arrow on the panel interior. A second person lifts from the bottom side of
the panel.
4. Rest the panel on a floor or flat horizontal surface until the installation personnel are ready
to begin the installation procedure.

Prepare for Installation 12
Installation Environment
For proper operation of the Echo Relay Panel Mains Feed, ensure that the intended installation
location conforms to the following environmental and electrical requirements.
•
Dry room (5%–95% humidity, non-condensing), 0°C–40°C (32°F–104°F) ambient
temperature, dust free.
•
A 120 V model of the Relay Panel Mains Feed can be either surface mounted or flush
mounted between studs; assuming 8.9cm (3.5 in) stud depth with 1.3cm (1/2 in)
surfacing material.
•
A 277 V model of the Relay Panel Mains Feed has a width of 50.8cm (20 in) and a depth of
14.7cm (5.8 in). Custom framing construction will allow the panel to be recessed to the
depth of the wall.
•
The installation location must support a fully populated panel, not exceeding 54.5kg
(120lbs).
Note: The maximum weight, 54.5kg (120lbs), includes a fully populated relay panel
as shipped from the factory and does not include the weight of installation conduit or
cable.
Electrical Input Requirements
•
Refer to Product Variants on page3 for information on mains feed for each panel model.
•
A single phase panel requires 192 A maximum continuous current to operate a fully loaded
panel.
•
A three phase panel requires 128 A maximum continuous current to operate a fully loaded
panel.
•
This equipment must be connected to a suitable safety earth/ground.
Parts and Specialty Tools Required
The following parts and specialty tools are required, but not supplied, for this installation:
•
Required mounting hardware (not supplied) six each 6–8mm (1/4–3/8 in) bolts or screws
5–10cm (2–4 in) long and suitable wall plugs are suggested.
Note: Both the installation location and the mounting hardware must support a fully
populated panel, including conduit and cable, approximately 54.5kg (120 lbs).
•
Torque wrench with 3/8 in, 5/16 in, 1/2 in, and 7/16 in hex sockets for feed wiring
•
Lineman’s pliers
•
Set of screwdrivers, including both flatblade and Phillips head. Specifically, a small 3mm
(1/8 in) flatblade screwdriver is required for data terminations.
•
Conduit punch or hole saw for providing access holes in the enclosure for conduit entry.
•
Insulation stripping tool
•
Precision wire stripper with self-adjusting blades or wire stripper that includes a fixed
opening for 23–24 AWG

Cable Routing and Conduit Access
When planning conduit entry and cable routing to the panel, pay special attention to the
following recommendations:
Purpose Top Entry Top Side
Entry Bottom Entry Bottom Side Entry
Feed wiring Yes Yes No No
Load wiring Yes Yes No No
Control wiring
(DMX, Network,
etc.)
Yes Yes Yes Yes
0-10V Output Yes Yes Yes Yes
Notes:
Do not install conduit in conflict with the option card locations on the
bottom panel or the low-voltage troughs specific to your installation.
For feed wiring, both copper and aluminum feeds are acceptable. For all
other wiring, use copper wire only.
Note: Control wiring (DMX, Network, etc.) and power wiring must be run in
separate conduit in accordance with local code.

15 Relay Panel Mains Feed Installation Manual
Low-Voltage Wiring Trough
One low-voltage wiring trough is preinstalled in the Relay Panel Mains Feed. This trough runs
the length of one side of the panel, allowing data and low-voltage cable routing from a top
entry installation. If required, you can move this trough to the opposite side of your panel.
Move Trough to Opposite Side
1. Remove the front covers to gain access to the low-voltage wiring trough. For information
on removing covers, see Installation on page17 .
2. Remove the four screws holding the trough in place.
3. Rotate the trough 180°.
4. Use the same four screws to reinstall the trough on the opposite side of the panel interior
as shown below.
