Power Terminal Block Wiring Specifications
Power Terminal Connection
IMPORTANT:
• Bulletin 161 Drives feature an electronic overload protection to monitor the motor current. In the
case of multi-motor operation, thermal contacts or PTC resistors must be used for each motor.
• In the case of motor lead lengths greater than 50 meters (165 feet), motor reactors should be used.
Branch Circuit Protection Devices
The following table shows the minimum recommended values for the branch circuit protection devices:
Input Power Conditioning
The drive is suitable for connection to input power within the rated voltage of the drive (see specifications).
The power factor of the input power supply must not exceed .99. Compensation systems must ensure that
over compensation does not occur at any time.
If the drive must be installed in any of the following conditions, an Input Line Reactor must be used:
Grounding
Ground the drive. Be sure to separate the drive’s grounding pole from those of other electrical machinery. If
multiple drives are used, make certain grounding connections do not create a loop as shown in Figure 2.5.

Input Power Condition Corrective Action
Line has intermittent noise spikes in excess of 2000V Install 3% impedance Input Line Reactor
If frequent voltage dips occur Install 3% impedance Input Line Reactor
The drive is operated on a generator Install 3% impedance Input Line Reactor
Line has power factor correction capacitors Install 3% impedance Input Line Reactor
Several drives are linked via a short common power supply bus bar. Install 3% impedance Input Line Reactor
ATTENTION
• The Bulletin 161 has a high leakage current and must be permanently (fixed) hard wired to ground.
Failure to observe this precaution could result in severe bodily injury or loss of life.
