Installationsanleitung
•
Use appropriate wiring to prevent short circuits to a supply line or between the inputs.
•
Use separate multi-core cable for supply voltage to avoid short circuits between the cable from the output (S37) and the
24 V DC supply line.
•
Connect shields at both ends to the grounded enclosures through a good electrical connection and through a large surface
area.
•
Connect cable shields as close as possible to the cabinet cable entry.
•
If possible, intermediate terminals should not interrupt cable shields.
•
Retain cable shields for both power cables and data cables using the appropriate EMC clamps. Ensure that the shield connec-
tion for control cables has a low induction.
If short circuits and cross circuits can be expected with safety-related signals, and if they are not detected by upstream devices,
protected cable installation is required as per EN ISO 13849-2.
1.5 Wiring the Option
For detailed information about wiring the control cables and configuring the safety option, refer to the VLT® Safety Option MCB
150/151 Installation Guide or VLT® Safety Option MCB 152 Installation Guide.
Procedure
1.
Remove the jumper wire between control terminals 37 and 12/13 (24 V).
Cutting or breaking the jumper is not sufficient to avoid short-circuiting.
2.
For FC 302, connect the safe output S37 on the safety option to terminal 37 on the control card (maximum length of this
wire is 100 mm (3.9 in)). For FCD 302, connect terminal B12 (safe output S37 on the safety option) to terminal 37 on the
terminal block. Section 2 in the Illustrations section shows the connection for both drive series.

a.
For VLT® Safety Option MCB 151 only: If the drive is fitted with VLT® Sensorless Safety Option MCB 159, additionally
remove the protective cap from the wire "TER4:ENC A" of the MCB 159 and connect it to terminal 4 (ENC A) of the
MCB 151, see section 2A in the Illustrations section.
3.
If required, connect the control cables to the safety option and relieve the cable with the enclosed cable strips.
4.
Remove the knock-out in the extended LCP frame so that the option fits underneath the frame.
5.
Fit the extended LCP frame and the terminal cover.
6.
Fit the LCP or blind cover in the extended LCP frame.
7.
Connect power to the drive.
