►
Basically all supply and signal cables must be laid separately�
►
Lay supply and signal cables away from the device using the shortest possible
route�
►
All connected cables must be provided with a strain relief max� 400 mm behind
the cable entry�
►
Cover unused terminals with dummy plugs / seals�
6.2 Connection accessories
Information about the available accessories at www�ifm�com
6.3 Frequency inputs
CR2050 / CR2052:
►
Operate frequency inputs with screened cables so that useful signals are not
affected by external interference�
6.4 Reverse polarity protection
Reverse polarity protection of the operating voltage is only ensured in case of
operation on an on-board system in connection with a fuse� In case of operation
via a power supply, there is no reverse polarity protection of the operating voltage�
CR2051: There is no reverse polarity protection of the CAN supply voltage, as this
voltage is not used within the device�
6.5 Supply of the signal generators at the inputs
CR2050 / CR2052:
►
Use sensor voltage VBB
S
of the corresponding connector as supply voltage for
the signal generators at the inputs (e�g� switches or sensors)�
►
If the input (switch or sensor) is supplied via an external voltage, protect this
voltage with max� 3 A�
6.6 Fuses
►
The individual electric circuits must be protected in order to protect the whole
system�
