Thank you for choosing this Eaton Logic Controller (ELC) series has
controllers with 10 to 40 embedded I/O points. To ensure proper installation,
operation and maintenance, please read this instruction sheet carefully
before installing ELCB-PB.
This instruction sheet provides only information on the electrical
specification, general functions, installation and wiring. It should be read
and understood before attempting to install or use the unit.
Further information can be found in the ELC series Programming
Manual.
These are OPEN TYPE controllers and therefore should be installed in
an enclosure free of airborne dust, humidity, electric shock and vibration.
Your application may require that the enclosure be locked to prevent
non-maintenance staff from operating the controller (e.g. key or specific
tools that are required for opening the enclosure) in cases where danger
and damage to equipment or personnel may occur.
DO NOT connect AC power to any of the DC I/O terminals; serious
damage may occur. Check all wiring before switching on power.
Ensure that the ground terminal is correctly grounded in order to
prevent electromagnetic interference.
This manual is subject to change without notice.
