Operating Instructions
enCore FC
ATTENTION!
Risk of short circuit
The enCore FC device can be damaged if lines are connected
while the device is connected to the power supply.
Always make sure the enCore FC is free of voltage before making
any changes to device wiring or before connecting sensor, supply,
signal or data lines.
The transmitter, pulse, signal and data lines are connected to the enCore FC
by using plug-in screw terminals that are located in a cable housing. Fixed
screw terminals are used for the power supply connection.
Special attention must be paid to the intrinsically safe electrical circuits.
Before switching on the power supply, the operator must ensure that the
plug connections for the gas meter, pressure and temperature inputs of the
ExMFE5 input board are inserted, since this is the only way the minimum
distance of 50 mm required in the relevant guidelines can be maintained.
The relevant installation guidelines must be observed when arranging the
wiring.
The device lines must be free of tensile stress and must be provided with a
kink protection if the enCore FC is being installed in a swivel frame.
Enough length must be allocated to cables so no tensile stress occurs in
cables when the swivel frame is opened up.
It is recommended that the lines be placed on transfer terminals in a switch
cabinet, and then be connected with the enCore FC from that point.
However, these terminals must sometimes fulfill Ex regulations, and must
also be sealable if applicable, for example in order to fulfill the requirements
of an applicable approval.
