General Electrical Recommendations
CAUTION! To avoid corrosion, overheating or general
damage, at terminal connections, unit is designed for
copper mono-conductors only. In case of multiconductor
cable, an intermediate connection box must be added.
For cable with alternative material, bi-material connecting
devices are mandatory. Cable routing inside control panel
should be made case by case by installer.
Do not allow conduit to interfere with other components,
structural members or equipment. Control voltage
(115V) wiring in conduit must be separate from conduit
carrying low voltage (<30V) wiring. To prevent control
malfunctions, do not run low voltage wiring (<30V) in
conduit with conductors carrying more than 30V.
WARNING!
The Warning Label is displayed on the equipment
and shown on wiring diagrams and schematics. Strict
adherence to these warnings must be observed. Failure
to do so may result in personal injury or death.
CAUTION! Units including RTWD HSE units must not
be linked to the neutral wiring of the installation. Units
are compatible with the following neutral operating
conditions:
TNS IT
Standard Special
* Differential protection should be suited for industrial
machinery with current leak which can be higher than
500 mA (several motors and frequency drives).
