Conductor Routing and Grounding
• Use separate metal conduits for routing the input power, output power, and control circuits.
• A separate ground cable should be run inside the conduit with the input power, output power, and
control circuits.
• DO NOT connect control terminal strip return marked LG to earth ground.
• Always ground the unit to prevent electrical shock and to help reduce electrical noise.
• It is the responsibility of the person installing the ASD or the electrical maintenance personnel to
provide proper grounding and branch circuit protection in accordance with all applicable national
and local electrical codes (in the U.S. refer to the current version of NEC).

Connections
Contact With Energized Wiring Will Cause Severe Injury Or Death.
• Turn off, lockout, and tagout all power sources before proceeding to connect the power wiring to
the equipment.
• After ensuring that all power sources are turned off and isolated in accordance with established
lockout/tagout procedures, connect three-phase power source wiring of the correct voltage to the
correct input terminals and connect the output terminals to a motor of the correct voltage and type
for the application. In the U.S., refer to NEC Article 300 – Wiring Methods and Article 310 –
Conductors For General Wiring and size the branch circuit conductors in accordance with NEC
Table 310.16. Outside the U.S., follow your national and local electrical codes.
• If multiple conductors that are smaller than the recommended sizes are used in parallel for the
input or output power, each branch of the parallel set shall have its own conduit and not share its
conduit with other parallel sets (i.e., place U1, V1, and W1 in one conduit and U2, V2, and W2 in
another) (refer to NEC Article 300.20 and Article 310.4 for U.S. requirements). National and local
electrical codes should be referenced if three or more power conductors are run in the same conduit
(in the U.S. refer to 2002 NEC Article 310 adjustment factors on page 70-142). Outside the U.S.,
consult your national and local electrical codes for additional requirements for running multiple
conductors.
• Ensure that the 3 phase input power is Not connected to the output of the ASD. This will damage
the ASD and may cause injury to personnel.
• Do not install the ASD if it is damaged or if it is missing any component(s).
• Turn the power on only after attaching and/or securing the front cover.
• Ensure the correct phase sequence and the desired direction of motor rotation in the Bypass
mode (if applicable).
