Echo Relay Panel Feedthrough Installation Manual
a: Strip 6mm (1/4”) of insulation from the end of the copper wire.
b: Insert the bare-end into the relay output screw terminal and secure.
Step 2:
Connect “Load” to the designated relay.
a: Strip 6mm (1/4”) of insulation from the end of the copper wire.
b: Insert the bare-end into the remaining relay output screw terminal and secure.
Step 3:
Repeat this process for the remaining Line and Load wires for the installation.
Connect Control Electronics Power Wiring
Control electronics input power connects in the ERP-FT on screw terminals. The transformer
is rated for 120V AC at 50/60Hz.
Step 1:
Connect line, Neutral and ground wiring on the designated screw terminals. Use the
diagram below to determine where each wire lands depending on voltage.
Step 2:
Tighten the screws firmly onto each wire.
Note:
Reference the circuit panel schedule for accurate terminations from circuit breaker
panel to Relay Panel then to lighting loads. The circuit panel schedule should be
maintained and stored on the inside door of the Relay Panel.
Note:
A Voltage Barrier may be used to separate multiple voltages and/or
emergency circuits from normal circuits within the Relay Panel. This is
an accessory option, sold separately, and available for use when local
code requires. Contact ETC for assistance.
CAUTION:
Dress the wire bundles neatly and remove all cuttings and dirt before proceeding
with the installation. Debris left in the panel may short the electronics at power up
and void the factory warranty.
WARNING:
RISK OF ELECTRIC SHOCK! Check power is OFF at the circuit breaker
prior to proceeding with control electronics power wiring.
Note:
When installing the ERP48-FT Relay Panel, input power connects to the transformer
in the top panel as indicated above. Standard ERP48-FT ships from the factory with
a power pigtail connected between the two transformers in the panel. To confirm an
accurate installation, reference
