10.1 Connection and safety information

Devices with cable glands and cable sockets
1. Ensure that the outside diameter of the cable used is
within the permissible clamping range (cable gland M12 x
1.5 cable dia. 3–6.5 mm, cable socket ISO 4400 cable dia.
4.5–10 mm). In addition, make sure that the cable is
seated securely in the cable gland, without any gaps.
2. Use a shielded, twisted multicore cable for the electrical
connection.
Devices with a cable outlet
Comply with the following minimum bend radii when laying
the cable:
• Cable without air hose:
Fixed in place: 5 x cable diameter
Flexible use: 10 x cable diameter
• Cable with air hose:
Fixed in place: 10 x cable diameter
Flexible use: 20 x cable diameter
On devices with a cable outlet and integrated vent tube, the
PTFE filter on the cable end on the gauge tube must not be
damaged or removed.
▶ Cables used for gauge devices have a vent tube for equal-
izing the pressure. Route the cable end into an area or
suitable terminal box that is as free from moisture and
corrosive gases as possible in order to prevent damage.
