Q9 Plus Bypass ASD/Bypass Box Installation and 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

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

Terminal Board

to the proper sensors or signal input sources

(see the section titled

I/O Monitoring and Control on pg. 26

for an expanded description of the system

control options).

The output terminals of the system (T1, T2, and T3) must be connected to the motor that is to be
controlled. See

Figure 7 on pg. 31

for the connection diagram.

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

Enclosure Dimensions/Weights on pg. 39

for

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
