Matters for Attention on Installation
Attention
Don't jam the vent on the device. Don’t insert other items into the machine, or it
may get fire.
Attention
Make sure the installation direction is correct.
Attention
Don't expose the machine to humidity gas, corrosive gas, water, and other
flammable material.
Matters for Attention on Cable Connection
Forbidden
Don't test the insulation of the circuit loop.
Forbidden
Never try to connect the overloaded electronic device on the connectors (like
sockets or terminals).
Attention
The insulation condition of each cable (no matter signal cable or power cable)
should be ensured.
Attention
The signal cables and power cables should be separated. Never tie them together.
Attention
All the cables should be well fixed. Don’t put any strength on cables. Make sure
each turning point of cable is well protected. Add shelter pipes to increase
insulating capability if necessary.
Attention
must be grounded. The equipment-grounding conductor should use the wire
with insulation having an outer surface that is green, with or without yellow
stripes. the cross-sectional area of the wire shall not be less than 2mm
2
, and the
grounding resistance should be less than 10Ω. The equipment-grounding
conductor must be pressed crimping to the circular pre-insulated terminal and
connected to the position where the grounding mark of the machine case is.
Matters for Attention on Operation
Danger
Don't operate the machine when there is any damage on the shelter of the running
parts.
Forbidden
When machine is running, do not touch any running part.
Attention
Make sure the configuration of power supply is in normal. Use stabilized voltage
power supply when the change of voltage is beyond the range of -10%~10%.
Attention
In case of warning, please check out the problem. Operation can only be carried
out again when problem is solved.
