G7 ASD Operation Manual 5
Mounting Requirements
• Only Qualified Personnel should install this equipment.
• Install the unit in a secure and upright position in a well-ventilated area.
• A noncombustible insulating floor or mat should be provided in the area immediately surrounding
the electrical system at the place where maintenance operations are to be performed.
• As a minimum, the installation of the equipment should conform to the NEC Article 110
Requirements For Electrical Installations, OS HA, as we ll as any o ther a ppli cable nati ona l, reg ional,
or industry codes and standards.
• Installation practices should conform to the latest revision of NFPA 70E Electrical Safety
Requirements for Employee Workplaces.
• It is the responsibility of the person installing the ASD or the electrica l maintenance personnel to
ensure that the unit is installed into an enclosure that will protec t personnel against electric shock.
Conductor Routing and Grounding
• Use separate metal conduits for routing the i nput power , output powe r , a nd cont rol circui ts a nd eac h
shall have its own ground cable.
• A separate ground cable should be run inside the conduit with the input power , output power, and
and control circuits.
•DO NOT connect control terminal strip return marked CC 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 electrica l maintenance personnel to
provide proper grounding and branch circuit protection in accordance with the 2002 NEC and any
applicable local cod es.
The Metal Of Conduit Is Not An Acceptable Ground.
Power Connections
Contact With Energized Wiring Will Cause Sever e 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 es tablished
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 (refer to NEC Article 300 – Wiring Methods and Article 310 – Conductors For
General Wiring). Size the branch circuit conductors in accordance with NEC Table 310.16.
• If multiple conductors that are smaller than the recommended siz es are us ed in par allel for the in put
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). National and local electrical codes should be
