Voltage supply
5.4.1
Line voltage
Connection line voltage to: PE, L1, L2, L3. In this regard, it is essential to ensure that the mains
voltage lies within the allowable tolerance speci
fi
cations (see technical data and name plate af
fi
xed to
the side).
UL note
The following information is intended for using the product in the USA or Canada and is therefore not taken into
consideration in translations.
Information
•
The system manufacturer must ensure that the used cables and connection comply with the
applicable national and local requirements such as the NEC (National Electrical Code) or the CEC
(Canadian Electrical Code).
•
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with the Manufacturer Instructions, National Electrical
code, the Canadian Electrical code, part I", and any additional local codes.
WARNING!
The opening of the branch circuit protective device max be an indication that a fault current has been
interrupted. To reduce the risk of
fi
re or electrical shock, current-carrying parts and other components
of the controlller should be examined and replaced if damaged. If burnout of the current element of an
overload relay occurs, the complete overload relay must replaced.
5.4.2
Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the de
fi
ned standard
voltages in IEC 60038!
5.4.3
Line protection fuse
The mains connection must be fused depending on the used cable, the type of routing, the operating
conditions and according to the standards applicable on site. The speci
fi
cation for the maximum
admissible line fuse of the device must be observed (see technical data).
Possible components for the line protection (recommendation):
•
Safety fuses of operating class
“
gG
”
(whole range fuse cartridges for general applications according
to EN 60269-1).
•
Line protection switch with characteristic
“
C
”
(according to EN 60898-1).
