Electrical connection
Only electricians are allowed to install accelerom-
eters. Comply with the national and international
regulations for the installation of electrical equip-
ment.
For the electrical connection to a
stationary
condition monitoring system (CMS), the following
connection cables are suitable.
For accelerometer
VIB 6.172
:
– Sensor cable with silicon coating and straight
cable connector, X meters long,
VIB 5.740-X
– Sensor cable with silicon coating and angled ca-
ble connector, X meters long,
VIB 5.741-X
– Sensor cable with PUR coating and straight ca-
ble connector, stainless steel, X meters long,
VIB 5.746-L
– Sensor cable with PUR coating and angled cable
connector, X meters long,
VIB 5.745-L
For accelerometer
VIB 6.210
:
– Sensor cable with angled cable connector, 10
meters long,
VIB 3.575-10
– Sensor cable with angled cable connector, 20
meters long,
VIB 3.575-20
Please find the technical data of the cables in
the sensor and cable catalogue, which you can
download from the PRUFTECHNIK website (www.
pruftechnik.com).
Lay the cable
• Lay the cable in a cable conduit or a protective
tube.
• Use Velcro strips or cable ties for mounting.
• Do not lay the connection cable parallel to pow-
er lines. Keep a minimum distance (> 1m).
• Lay a cable loop with sufficient excess cord at
each connection or before each gland.
• Label the cable ends to avoid confusion.
• Observe the terminal assignments on the CMS
(see CMS installation manual).
Extend the cable
• Observe the maximum cable lengths (see CMS
installation manual).
• Use shielded, 2-wire electrical cables for exten-
sion.
• Connect the cable ends in a junction box.
• Mount a metal junction box electrically insulat-
ed.
EMC protection
• Use double-shielded triaxial cables in environ-
ments exposed to strong electromagnetic radi-
ation.
• Keep the accelerometer connection cable as
short as possible.
• Connect the triaxial cable and the accelerome-
ter connection cable in a junction box.
• Mount the junction box close to the accelerom-
eter.
