3.1 General Safety Information
Proper Use
SINAMICS Perfect Harmony™ GH180 medium voltage drives must always be installed in closed
electrical operating areas. The drive is connected to the industrial network via a circuit-breaker
or contactor that is electrically connected to the VFD control to enable the drive protection
features.
The specic transport conditions must be observed when the equipment is transported. The
equipment shall be assembled/installed and the separate cabinet units connected properly by
cable and/or busbar in accordance with the assembly/installation instructions. The relevant
instructions regarding correct storage, EMC-compliant installation, cabling, shielding and
grounding and an adequate auxiliary power supply must be strictly observed. Fault-free
operation is also dependent on careful operation and maintenance.
The power sections are designed for variable-speed drives use with synchronous and
asynchronous motors. Operating modes, overload conditions, load cycles, and ambient
conditions dierent to those described in this document are allowed only by special
arrangement with the manufacturer.
Commissioning should only be carried out by trained service personnel in accordance with the
commissioning instructions.
System components such as circuit-breaker, transformer, cables, cooling unit, motor, speed
sensors, etc., must be matched to VFD operation. System conguration may only be carried out
by an experienced system integrator.
