Context:
WAR N I N G
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
-
Ensure the correct grounding of the equipment by a certified electrical installer.
NOTI C E
POTENTIAL EQUALIZATION
There is a risk of burst transient when the ground potential between the drive and the control system is different.
-
Install equalizing cables between the system components. Recommended cable cross-section: 16 mm
2
(5 AWG).
1. Strip a section of the outer cable insulation.
2. Fasten a connector/cable lug to the end of the stripped cable.
3. Connect the ground cable to the nearest grounding terminal.
4. Tighten the terminals in accordance with the specifications shown in 10.11 Fastener Torque Ratings.
Example:
1 Symbol indicating grounding terminals
3 Grounding bar (provided in every cabinet)
2 Grounding points on drive module
