Input Power Conditioning
The drive is suitable for direct connection to input power within
the rated voltage of the drive. Listed in
are certain input power conditions which may cause component
damage or reduction in product life. If any of the conditions exist,
install one of the devices listed under the Possible Corrective Ac-
tion(s).
IMPORTANT: Only one device per branch circuit is re-
quired. It should be mounted closest to the branch and
sized to handle the total current of the branch circuit.
Input Power Condition
Possible Corrective Action(s)
Low Line impedance (less than 1% line reactance)
• Install Line Reactor
• Isolation Transformer
Greater than 120 kVA supply transformer
Line has power factor correction capacitors
• Install Line Reactor
• Isolation Transformer
Line has frequent power interruptions
Line has intermittent noise spikes in excess of 3000V (lightning)
Phase to ground voltage exceeds 125% of normal line to line
voltage
• Remove MOV jumper to ground
• Install Isolation Transformer with grounded secondary (if
necessary)
Ungrounded distribution system
240V open delta configuration (stinger leg)*
• Install Line Reactor
* For drives applied on an open delta with a middle phase grounded neutral system, the phase opposite the phase that is tapped in the
middle to the neutral or earth is referred to as the “stinger leg,” “high leg,” “red leg,” etc. This leg should be identified throughout
the system with red or orange tape on the wire at each connection point. The stinger leg should be connected to the center Phase B
on the reactor.
Table 31
Input Voltage Requirements
For voltages above or below listed specifications, contact your
power company or local electrician.
IMPORTANT: Improper connections will result in equip-
ment damage and will void warranty.
DANGER
Electrical shock hazard will result in death or serious
injury. Disconnect electric power and wait five (5) mi-
nutes before servicing.

Circuit Breakers and Quick Disconnects
Single-phase machines require a single-phase inverse-time circuit
breaker. Three-phase machines require a separate, three-phase in-
verse-time circuit breaker to prevent damage to the motor by dis-
connecting all legs if one should be lost accidentally. Refer to
sections for model-
specific circuit breaker requirements.
IMPORTANT: All quick disconnects should comply with
the specifications. DO NOT use fuses instead of circuit
breakers.
Connection Specifications
IMPORTANT: Connection must be made by a qualified
electrician using wiring diagram provided with ma-
chine, or according to accepted European Union stand-
ards.
Connect machine to an individual branch circuit not shared with
lighting or other equipment. Shield conductors in a liquid-tight or
approved flexible conduit. Copper conductors of correct size
must be installed in accordance with National Electric Code
(NEC) or other applicable codes.
Use wire sizes indicated in the Electrical Specifications chart for
runs up to 50 feet [15 m] . Use next larger size for runs of 50 to
100 feet [15 to 30 m] . Use two (2) sizes larger for runs greater
than 100 feet [30 m] .
IMPORTANT: For X voltage - To obtain 200-240V from a
200-240V source, connect L1 and L2. To obtain
220-240V from a 380-415V source, connect L1 and N.
