1. INTRODUCTION

The Alpha2 Series Controllers provides supervisory control for use in

the home, office, factory, or wherever you need it. The Alpha2 Series

Controllers offers flexible I/O control for varied applications including:

• Automation of lights, air-conditioning, or watering systems

• The opening and shutting of gates

• Easy security systems

• Domestic animal and pet food distribution systems

• Control of stockyards and greenhouses

However, the Alpha2 Series Controllers is not designed to be used in

the following applications:

• Applications where high reliabilities such as nuclear power control,

railway facilities, airline facilities, vehicles, combustion equipment

and medical equipment are required.

• Applications in life critical situations

1.2 CAUTION

standards must perform all tasks associated with wiring the Alpha2

Series Controller.

• Disconnect all terminals from power supply before removing the

cover.

• Turn off the power before performing any wiring operations.

• Input and output cables should not be run through the same

multicore cable or share the same wire.

• Input and output cable length must be less than 30m (98' 5").

• The wire should be used a single cable, used a crimp terminal, or

carefully twist stranded wires together. Do not connect a soldered

wire end to the Alpha2 Series Controller.

• To avoid damaging the wire, tighten to a torque of 0.5 - 0.6 N•m.

• Do not install in areas with: excessive or conductive dust, corrosive

or flammable gas, moisture or rain, excessive heat, regular impact

shocks or excessive vibration.

• The connectors must be covered to prevent contact with “live” wires.

• The Alpha2 Series Controller must be installed in distribution box or

a control cabinet.

• Leave a minimum of 10mm of space for ventilation between the top and

bottom edges of the Alpha2 Series Controller and the enclosure walls.

• The Alpha2 Series is not designed to be used in life critical or fail

safe applications.

• Under no circumstances will Mitsubishi Electric be liable or

responsible for any consequential damage that may arise as a result

of the installation or use of this equipment.

• Please read this entire manual for further information.

MOUNTING NOTES

The Alpha2 Series’ safe design means the user can install it almost

anywhere but please take the following points into consideration.

• Do not install in areas with excessive or conductive dust, corrosive

or flammable gas, moisture or rain, excessive heat, regular impact

shocks or excessive vibration. Do not place in water or let water leak

onto the controller.

• Do not allow debris to fall inside the unit during installation.

• Keep as far as possible from high-voltage cables and power

equipment.

• The Alpha2 Series Controller must be installed in a distribution box

or a control cabinet.
