CE 230V Emergency Modules
230V CE Emergency modules are non-standard for DRd 230V enclosures. On the
occasion that your installation requires use of these modules, refer to the information
outlined below for installation.
About Emergency Modules
The 230V CE Emergency modules provide two live outputs, one of which is dimmed or
switched, and one of which is live whenever the breaker is turned “On”. This setup allows
the modules to control battery-backed lighting, which requires both a constant and a
switched or dimmed feed.
ETC offers two varieties of Emergency Modules - ED15AFE (15A Dimmer), and
ER15AFE(15A Relay), painted red for easy identification.
Wire Termination
The constant output from the module is connected to the Neutral lugs at the left of the
enclosure. Therefore, unlike Neutral Disconnect modules, Emergency modules provide a
live output at these lugs, not a neutral connection.
Step 1: Locate the module slot in the enclosure where the Emergency module is to be
fitted.
Step 2: Terminate the outgoing dimmed line to the terminals at the right hand side of the
enclosure.
Step 3: Terminate the outgoing (constant feed) line to the terminals at the left side of the
enclosure.
Step 4: Terminate the outgoing (Earth) line to the earth bar terminals.
N o t e : When configuring the dimmer modules at the Architectural Control Processor,
configure as either the ED15 or the ER15 module type.
N o t e : ETC does not offer a Neutral Disconnect or RCD version of the emergency
modules.
