ABB 3BHB001914R0001 Redundant module

The resistor terminals are standard 0.25″ fast-ons. The resistor can be mounted any distance from the drive using a customer supplied cable. Recommended cable wire is #16 AWG, 600V rated, teflon

The terminals of the regen resistor

 must be shielded from contact as they are electrically connected to the +Bus of the drive. The regen terminals are at dangerous, potentially lethal, voltages whenever the drive bus power is on and for about 10 minutes after bus power is turned off. To prevent the metal case of the resistor from becoming a safety hazard in the event of internal resistor failure the resistor case should be grounded by attaching it to a grounded panel.

Non-PacSci Regen Resistors

 Customer supplied regen resistor(s) can be used. Be sure the resistance seen by the drive is within 10% of 12.5 Ω and the isolation of the resistive element is a minimum of 1,500 V. Two 25 Ω resistors in parallel form a 12.5 Ω resistor.
