CAUTION: Persons trained in the local and national electrical
standards must perform all tasks associated with wiring the Alpha2
Series Controller.
3 INSTALLATION
n MOUNTING NOTES
The Alpha2 Series’ safe design means the user can install it almost
anywhere but please take the following points into consideration.
• Disconnect all terminals from power supply before removing the
cover.
• Turn off the power before performing any wiring operations.
• 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.
• 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").
• Do not allow debris to fall inside the unit during installation.
• 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.
• 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.
• 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.
