4.4 Mounting and connecting cables

All cables to be connected to UNIGAS 300 must be shielded. UNIGAS 300 comes with cable glands fitted with
EMC shielding to which the shield is to be connected according the step-by-step mounting instruction below.

1: Remove the sheath over 35 mm

2: Remove shield. Strip the cores over 7 mm

3: Place cable crimps

4: Remove the sheath over 20 mm

5: Take the nut and the seal from the gland

and slide them over the cable

6: Press down the shield to fold it back
