Mounting Requirements; Conductor Requirements And Grounding; Power Connections - Toshiba Q7 Installation And Operation Manual

Mounting Requirements

• Only Qualified Personnel
• 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, OSHA, as well as any other applicable national, regional,
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 electrical maintenance personnel to
ensure that the unit is installed into an enclosure that will protect personnel against electric shock.

Conductor Requirements and Grounding

• Use separate metal conduits for routing the input power, output power, and control circuits and each
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 electrical maintenance personnel to
provide proper grounding and branch circuit protection in accordance with the 2005 NEC and any
applicable local codes.

• 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 (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.
• Adhere to the recommended conductor sizes listed in the section titled
Specifications on pg.
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 referenced if
