18 ACR7000 Controller Installation Guide
Installation Safety Requirements
The ACR7000 Controller has been shown to meet the CE requirements for Electromagnetic Compatibility (IEC
61800-3 ed2.0 per 204/108/EC) when installed, operated and maintained as described in the product User Guide.
As a rule, it is recommended that the ACR7xC be 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 such cabinets 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.
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 can produce 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
