Mounting And Connections; Mounting The Q9 Plus Bypass Asd - Toshiba Q9 Plus Bypass ASD Installation & Operation Manual

Mounting and Connections

The Q9 Plus Bypass ASD/Q9 Plus Bypass Box is available in two typeform-specific versions: the one-
part system (the ASD and the Bypass system in one enclosure) and the two-part system (the ASD and
the Bypass Box as two separate components).
The mounting and connection requirements vary when discussing the one-part and the two-part
systems. The two-part system is identified as the BYP Series or Bypass Box in this publication. The
term Q9 Plus ASD/Q9 Plus Bypass Box will be used throughout this publication to address both types
unless addressing specifics of the BYP Series. The systemic functionality is identical for both system
versions, and no differentiation is required. Mechanical enclosure differences are specified as required.
The Q9 Plus Bypass ASD/Q9 Plus Bypass Box may be set up initially by performing a few simple
system configuration connections and settings. To operate properly, the Q9 Plus Bypass ASD/Q9 Plus
Bypass Box must be securely mounted and connected to a power source (three-phase AC input at the
L1, L2, and L3 terminals). The control terminals of the Q9 Plus Bypass ASD/Q9 Plus Bypass Box may
be used by connecting the terminals of the
(see the section titled
control options).
The output terminals of the system (T1, T2, and T3) must be connected to the motor that is to be
controlled. See
As a minimum, the installation of the ASD shall conform to Article 110 of the NEC, the Occupational
Safety and Health Administration requirements, and any other local and regional industry codes and
standards.

Mounting the Q9 Plus Bypass ASD

The ambient operating temperature rating for the Q9 Plus Bypass ASD/Q9 Plus Bypass Box is from
14° to 104° F (-10° to 40° C).
The process of converting AC to DC and then back to AC produces heat. During normal ASD
operation, up to 5% of the input energy to the ASD may be dissipated as heat.
Install the Q9 Plus Bypass ASD securely onto a vertical surface using the four mounting holes on the
top and bottom of the enclosure.
Mount the system in a location that is in a well-ventilated area that is not in the path of direct sunlight.
When installing multiple ASDs, ensure that there is a clearance space of at least 8 inches (20 cm) from
the top and the bottom of adjacent units. Ensure that the ventilation openings are not obstructed. There
should be at least 5 cm (2 inches) on either side of adjacent units. For the models below 50 HP, the top
and bottom clearance specifications may be reduced to 4 inches (10 cm). This space ensures that
adequate ventilation is provided (see the section titled
additional information on mounting space requirements).
DO NOT operate the ASD with the enclosure door open.
ASDs produce high-frequency noise — steps must be taken during installation to avoid the negative
effects of noise. Listed below are some examples of measures that will help to combat noise problems.
• Separate the input and output power conductors of the main circuit. DO NOT install the input and
output wires in the same duct or in parallel with each other, and DO NOT bind them together.
• DO NOT install the input or output power conductors of the main circuit and the wires of the
control circuit in the same duct or in parallel with each other, and DO NOT bind them together.
