The Grounding Capacitor Switch allows the user to
quickly change the value of the leakage-reduction
capacitance of the 3-phase input circuit without the
use of any tools.
See the section titled Power Connection
Requirements on pg. 11 for more on the Grounding
Capacitor Switch.
See figures 4 , 5 , 6 , and 7 on pg. 12 for an electrical
depiction of the leakage-reduction functionality of
the
Grounding Capacitor Switch and the methods
used to set the capacitance value.
Power Connections
CONTACT WITH ENERGIZED WIRING WILL
CAUSE SEVERE INJURY OR LOSS OF LIFE.
• Turn off, lock-out, and tag-out 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
lock-out/tag-out procedures, connect the 3-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 are used in parallel for the
input or output power and it is necessary to use
separate conduits, each parallel set shall have its
own conduit (i.e., place U1, V1, W1, and a ground
wire in one conduit and U2, V2, W2 and a ground
wire in another; refer to 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
NEC Article 310 adjustment factors).
•
DO NOT
connect the 3-phase input power to the
output of the ASD. This will damage the ASD and
may cause injury to personnel.
•
DO NOT
connect resistors across terminals PA –
PC or PO – PC. This may result in fire.
• Ensure the correct phase sequence and the
desired direction of motor rotation in the Bypass
mode (if applicable).
Protection
• Ensure that primary protection exists for the input
wiring to the equipment. This protection must be
able to interrupt the available fault current from
the power line. The equipment may or may not be
equipped with an input disconnect (option).
• All cable entry openings must be sealed to
reduce the risk of entry by vermin and to allow for
maximum cooling efficiency.
• It is the responsibility of the ASD installer/
maintenance personnel to setup the Emergency
Off
braking system of the ASD. The function of
the Emergency Off braking function is to remove
output power from the drive in the event of an
emergency. A supplemental braking system may
also be engaged in the event of an emergency.
For further information on braking systems see
parameter
F250 .
Note: A supplemental emergency stopping
system should be used with the ASD.
Emergency stopping should not be a
task of the ASD alone.
• Follow all warnings and precautions and do not
exceed equipment ratings.
System Integration
Precautions
The following precautions are provided as general
guidelines for the setup of the ASD within the
system.
• The TIC ASD is a general-purpose product. It is a
system component only and the system design
should take this into consideration. Please
contact the TIC Customer Support Center for
application-specific information or for training
support.
• The TIC ASD is part of a larger system and the
safe operation of the ASD will depend upon
observing certain precautions and performing
proper system integration.
• Improperly designed or improperly installed
system interlocks may render the motor unable to
start or stop on command.
• The failure of external or ancillary components
may cause intermittent system operation (i.e., the
system may start the motor without warning).
