1.2 General Safety Precautions
Read the following safety precautions before attempting installation or operation of the
unit.
Risk of serious injury or death due to electric shock, moving parts and
hot surfaces!
ï‚„ AC motor controls and servo drives contain dangerous voltages which can
cause death or serious injury.
ï‚„ During operation they can have "energized" un-insulated parts, moving
parts, as well as hot surfaces.
ï‚„ Care should be taken to ensure correct and safe operation in order to
minimize risk to personnel and equipment.
Risk of serious injury or death due to electric shock!
Note capacitor discharge time!
ï‚„ Before any installation and connection work can be done, the supply
voltage must be turned off and locked out.
ï‚„ After turning off the supply voltage, dangerous voltages may still be
present within the unit as the bus capacitors discharge. Therefore it is
necessary to wait 5 minutes before working on the unit after turning off the
supply voltage.
Risk of serious injury or death due to electric shock!
Secure isolation!
ï‚„ The low voltage control terminal strip and communication ports are
securely isolated in accordance with EN50178.
ï‚„ When connecting to other systems, it is necessary to verify the insulation
ratings of these systems in order to ensure the EN requirements are still
met.
ï‚„ When connecting the unit to a grounded delta power system, the control
circuit can no longer be classified as a "securely isolated circuit".
Risk of property damage, serious injury or death due to electric shock!
ï‚„ Before putting the motor control into operation, be sure the connection
terminals are tight and all covers removed for installation have been
replaced.
