6 GX7R ASD Quick Start Guide
• Under no circumstances in a multiple ASD or multiple motor system configuration shall the input
power or output power cables of the system ASDs or motors be routed within a shared conduit.
Each ASD and each motor shall have its own conduit for input power and output power cable
routing.
• Ensure that the phase sequence connection for the device is C-B-A.
• Ensure the correct direction of motor rotation in the Bypass mode (if applicable).
• The GX7R ASD is designed to operate on utility power ONLY .
• DO NOT CONNECT THE GX7R ASD 3-PHASE INPUT TO A GENERATOR.
Protection
• Ensure that primary protection exists for the input wiring to the equipment. This protection must be
able to interrupt the fault current from the power line. The equipment may or may not be equipped
with an input disconnect (option).
• All cable entry openings must be sealed to reduce the risk of entry by vermin and to allow for
maximum cooling efficiency.
• If the ASD is supplied with a motor as a package, it then becomes a machine and has to meet the
Essential Health and Safety Requirements of the EU Machinery Directive, 2006/42/EC. It is also a
requirement that the system have an
Emergency Off function that meets the requirements of EN
ISO 13850:2008, and that any local or regional requirements must be met.
• It is the responsibility of the ASD installer/maintenance personnel to set up the Emergency Off
braking system of the ASD. The function of the Emergency Off braking function is to remove
output power from the ASD in the event of an emergency. A supplemental braking system may also
be engaged in the event of an emergency. For further information on braking systems, see
parameters
F250 , F304 , and F603 .
Note: A supplemental emergency stopping system should be used with the ASD. Emergency
stopping should not be a task of the ASD alone.
• Follow all warnings and precautions and do not exceed equipment ratings.
