Electrical connection
!
IMPORTANT!
• Ensure the motor protection is set to the correct ampere setting for the
motor.
Incorrect electrical connection may lead to personal injury or damage to the
conveyor equipment and/or other equipment. It can also cause malfunctions
or a reduction in capacity.
!
IMPORTANT!
• If the machine is being assembled outdoors, the motors and
transmissions must be fitted with a weather cover.
• If a machine or part thereof in any way needs moving/dismantling,
follow the directions given in the assembly instructions.
• The machine can be stopped and restarted when full of material but
this option must not be used for intermittent operation.
• If a short circuit should occur, ensure that the electrical equipment is
in working order before continuing operation.
• Ensure that the electrical equipment is kept free from dirt, dust,
moisture and electrostatic charge.
• The machine is not designed to stand or walk on.
!
WARNING!
• The sweep conveyor's conveyor chain and forward driving wheel are not
fully built-in for functional reasons. Do not remain in the vicinity of the
machine while it is operating.
• The silo's centre and intermediate outlet hoppers are not protected for
functional reasons. Do not remain in the vicinity of the outlet hoppers
while the machine is operating.
• Connections to, from and between machinery must be permanently
mounted and fully enclosed. If the design of the installation does not
allow this at an outlet, finish off with a 1 m pipe.
• Ensure the machine is anchored and braced as described in the
assembly instructions.

manufacturer Nord.
Check the oil level before taking into service and at regular intervals
thereafter.
Change oil every 10,000 operating hours or at least every other year.
The interval between changes can be doubled if synthetic oil is used. When
operating in severe conditions such as high humidity, aggressive environment
or large temperature variations, the oil must be changed more often.
Clean the gear when changing oil.
Return rollers chain conveyors / Belt conveyor carrying
idlers, return idlers, snub idlers and tracking idlers
Check rollers/idlers annually. Replace them immediately if they are worn.
Belt conveyor return idlers, snub idlers, tail pulley
