Electrical Installation Safety
4.1
OVERHEATED CABLES
Overheated cables are a fire hazard.
Because of several possible cable installations and environmental conditions, it is important to consider
l
local regulations and IEC/EN standards.
Route the wires away from sharp edges, screw threads, burrs, fins, moving parts, drawers, and similar parts, which can abrade the wire
insulation.
For the main circuit, use double insulated wires or protect the wires with, for example, a protective sleeve or wrap to minimize the risk of
short circuit. Maintain separation between the main and control circuit wires.
4.2 Installing the dU/dt Filter
Install the dU/dt Filter at the inverter output. If the inverter has parallel power units, install a separate dU/dt Filter at the output of each
power unit. See 4.10 Wiring
