Installation Safety Requirements
ACR7000 series meets the requirements of both the European LVD (Low Voltage Directive) and EMC
(Electromagnetic Compliance) directives when installed according to the instructions given within
As a rule, it is recommended that the drive/controller is installed in an enclosure to protect it from atmospheric
contaminants and to prevent operator access while power is applied. Metal equipment cabinets are ideally suited
for housing the equipment because they provide operator protection and EMC screening, and can be fitted with
interlocks arranged to remove all hazardous motor and drive power when the cabinet door is opened.
Do not arrange the interlocks to open circuit the motor phase connections while the system is still powered as this
could damage the product
Precautions
During installation, take the normal precautions against damage caused by electrostatic discharges.
•
Wear earth wrist straps.
•
Include a mains power switch or circuit breaker within easy reach of the machine operator. Clearly label
the switch or breaker as the disconnecting device.
Warning: High-performance motion control equipment is capable of producing rapid movement
and very high forces. Unexpected motion may occur especially during the development of
controller programs. KEEP WELL CLEAR of any machinery driven by stepper or servo motors. Never
touch any part of the equipment while it is in operation.
