5 Installation and Wiring
Mounting Vibration Sensor Head Easily
For the K6CM-VBS1 (M6 × 8 mm), a magnet for easy-mounting of the sensor is included.
The easy-mounting magnet is used for positioning of measuring place. Note that measurement accu-
racy is not guaranteed in the case of magnet mounting.
The connection between the pre-amplifier and the sensor head is a connector connection.

Installation of the insulation resistance sensor (ZCT (IRT)

Insulation resistance sensor ZCT (IRT) used for Insulation resistance type (K6CM-IS) is fixed on the
wall etc and used.
Precautions for Correct Use
Insulation resistance sensor ZCT (IRT) must be installed inside the cabinet.
Fastening of the Insulation resistance sensor (ZCT (IRT))
Secure the ZCT (IRT) to the wall with screws.
Precautions for Correct Use
If it is used without fixing, the cable may become overloaded and the cable may be discon-
nected.
Use ZCT (IRT) in the cabinet. (If you use it outside the panel, the error may increase due to the
influence of noise.)
Since the measurement accuracy deteriorates due to the influence of the external magnetic
field, install ZCT (IRT) more than 40 cm from the electric wire through which the large current
flows. (It is a standard of 40 cm at 100 A, 10 cm at 40 A.)
