3.2.3 Cable gland and connection
All cables have to be fed into the instrument via glands to ensure protection according to IP 65. Cable
diameters of 6...12 mm for PG13.5, 5...10 mm for PG11 and 4...8 mm for PG9 are suitable. The conductors are
connected to screw terminals in the instrument. Max. conductor cross-section 2,5 mm
2
.
The strip connectors are mounted on the housing bottom, above the holes for the EMC glands. The power
connecting terminals excepted, all connecting terminal units are of the plug-in type. The conductors taken to
the terminals shall be as short as possible. The conductors of each cable must be tied together with a cable
strap shortly before the terminal block.
Mounting the cable:
• Remove the (screw) cap
• Slide cap and plastic cone over the cable
• Take the cable through the gland
• Fold the cable screen over the lower part of the
plastic cone (approx. 10mm)
• Connect the cable conductors
• Tighten the PG-gland
The cable screens must be connected in the metal sleeves of the PG gland.
Don’t take the screens into the unit!
