The chromatograph is supplied with a 4-m long cable. The cable has a diameter of 18 mm.
Connect all cores of the power supply in accordance with the following table since one single
core is insufficient for the maximum current. The cable must be securely routed and
terminate in a terminal box with approved type of protection.
Appropriate cable gland: M32 with a terminal areas from 13 to 21 mm.

Permissible cable length
The power supply on the chromatograph must be
● up to AS07: 24 V DC (-15 ... +10%)
● from AS08 onwards: 24 V DC (18.5 ... 30.2 V)
If the power supply delivers exactly 24 V DC, and if only one chromatograph is connected,
the following cable lengths are permissible between the power supply and the
chromatograph depending on the cable cross-section (distance = half the cable length):
