Conductors And Grounding; Power Connections - Toshiba Q9 Installation And Operation Manual

Conductors 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 the CC terminal of the Terminal Board 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 Q9 F
personnel to provide proper grounding and branch circuit protection in accordance with the NEC
and any applicable local codes.

• Turn off, lockout, and tagout all power sources before proceeding to connect the power wiring to
the equipment.
• Ensure the correct supplied voltage, wiring used, and system type for the application (refer to the
NEC Article 300 – Wiring Methods and Article 310 – Conductors For General Wiring). Size the
branch circuit conductors in accordance with NEC Table 310.16.
• Only after ensuring that all power sources are turned off and isolated in accordance with
established lockout/tag out procedures, shall a three-phase power source of the correct voltage be
connected to the input terminals and the system output terminals be connected to a motor.
• 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 the
NEC Article 300.20 and Article 310.4). National and local electrical codes should be referenced if
three or more power conductors are run in the same conduit (refer to the NEC Article 310
adjustment factors).
• Ensure that the 3-phase input power is Not connected to the output of the Q9 F
damage the system and may cause injury to personnel.
• DO NOT install the Q9 F
• DO NOT connect resistors across terminals PA – PC or PO – PC. This may cause a fire.
• Ensure the correct phase sequence and the desired direction of motor rotation in the Bypass mode
(if applicable).
• Turn the power on only after attaching and/or securing the front cover.
