How To Install Pg Cable Glands On A Ukk Splitter Box Step By Step
To install a PG series cable gland on a UKK splitter box, insert the gland body into the enclosure knock-out hole, secure it tightly with the locknut from the inside, thread the cable through the sealing nut and claw, connect the wires inside, and torque the outer dome nut until the internal neoprene seal compresses fully around the cable sheath.
Essential Preparation and Wire Routing
Proper installation ensures an IP68 ingress protection rating, preventing moisture and dust penetration. Before mounting, verify that the PG thread pitch matches the box knock-out size. Stripping outer insulation to the precise length prevents unshielded conductors from exposing outside the enclosure.
| Component Part | Recommended Torque Range | Primary Function |
|---|---|---|
| Enclosure Locknut | 2.5 - 3.5 Nm | Structural Mounting |
| Cable Sealing Nut | 3.0 - 4.5 Nm | Strain Relief & IP Rating |
| Internal Terminals | 2.0 - 2.5 Nm | Electrical Contact |
Positioning a single pole distribution block inside the housing requires leaving adequate bend radius for incoming power lines. Clean all mounting surfaces thoroughly to allow the rubber O-ring to sit flat against the outer wall without pinching or distortion.
Step-by-Step Gland Assembly Techniques
-
Unscrew the dome nut and remove the split sealing ring from the gland assembly.
-
Insert the main thread through the pre-drilled wall opening of the enclosure.
-
Thread the locknut onto the internal side, tightening securely using a open-ended spanner.
-
Push the stripped power cable through the sealing rubber grommet and internal claw.
-
Secure the conductor leads directly into the modular distribution block terminals.
When terminating heavy-gauge supply lines, ensure conductor strands remain straight without fraying. Connecting a robust terminal block 250a rating demands precise torque application on internal clamping screws to avoid localized thermal expansion during operation.
Ensuring Long-Term Environmental Sealing
To achieve optimal strain relief, tighten the outer compression nut until the internal claw tightly grips the outer jacket. Never over-tighten, as excess compression deforms the elastomer seal and compromises weather protection.
Proper wire alignment inside a din power distribution block reduces mechanical stress on the cable gland assembly, preserving IP ratings over extended operational cycles in industrial environments.
