Electrical shock hazard. DC bus voltages may be present at these terminals.
Use a suitable heatsink (with fan if necessary) to cool the regeneration
resistor. The regeneration resistor and heatsink (if present) can reach
temperatures in excess of 80 °C (176 °F).
An optional regeneration resistor may be required to dissipate excess power from the DC bus
during motor deceleration. Care should be taken to select the correct resistor for the application
- see section 3.9. Suitable resistors are are listed in section A.1.4. The regeneration resistor
output is fully short-circuit proof according to EN61800-5-1, 6.2.

For 1.5 A ~ 16 A models, tightening torque for X1 terminal block connections is 0.5-0.6 N·m
(4.4-5.3 lb-in). The 48 A ~ 65 A models use a spring cage connector.
