Installation
The ALCR-PP (Power Pack) model is designed for permanent installation directly to an
electrical junction box or panel at the electrical lighting load or before the load in the
circuit. Reference
"Installation and Termination of the ALCR-PP"
.
The ALCR-DIN (DIN-rail) model is designed to be permanently installed on a consumer
DIN rail 35mm (complies with DIN43880 and EN60715). Reference
"Installation and
Termination of the ALCR-DIN"
on page 4.
Once installation of the Automatic Load Control Relay is complete, reference
"Configuration of Time Delay" on page 6
.
Installation and Termination of the ALCR-PP
The ALCR-PP mounts directly to an electrical junction box or electrical enclosure at the
electrical lighting load or before the load(s) in the circuit. The ALCR-PP is fitted with a
1/2” nipple (standard 1/2” knockout).
Two sets of wire bundles are provided on the unit. One set is for emergency power input
and the other set is for sensing normal power. In addition, a single loop jumper is
provided for connection to a remote triggering device (normally closed, maintained dry
contact closure for fire alarms, etc.).
WARNING:
Before terminating the AC power wiring verify the breakers for the normal
power and emergency power are in the off position and follow the proper
lockout/tag out procedures per NFPA Standard 70E.
N o t e :
The ALCR-DIN must be mounted in a suitably insulated or grounded enclosure,
such that live terminals are not accessible.
WARNING:
For indoor use only! Must install in an electrical junction box or wire way.
Follow local codes and restrictions.
