Fluke VIBGUARD compact, Manual, Page: 36 / 50

To connect a signal cable to the terminal block, proceed as follows:
l
Open one of the large cable glands (M32) using a suitable spanner (Size 36).
l
Take out the seal.
l
Remove a sealing insert.
l
Place a cable loop in order to not put any strain on the connection during subsequent service work.
l
Insert the open cable end through the seal (max. Ø 5.3 mm). If necessary, apply some silicone oil to the
cable sheath.
l
Crimp ferrule sleeves onto the wire ends.
l
Prepare the screen for connection, e.g. using the screen connection set VIB 6.725-100.
l
If necessary, insulate exposed screen with shrink tubing. The screen must not come into direct contact with
the protective housing or other conductive components.
l
Connect the wires to the relevant terminals.
l
Re-tighten the cable gland.
l
Mark the cable on the sensor and system side to make it easier to identify cable routes when performing
service work.
Note
Damage or incorrect measurements when feeding in analog signals
When feeding in analog process signals without potential separation, potential differences may arise
which damage the inputs or result in incorrect measurements.
Input resistance of the voltage inputs = 200 kOhm.
Observe the internal resistance of high-impedance voltage sources!
Galvanically isolate and feed in process signals. Determine compatibility with the CMS through tests.
Use suitable buffers.
