Installing the K-Box
Step 1
Remove power
from the electrical panel.
Step 2
Remove the
cover panel
so you can access the wires.
Step 3
Verify that there is no tension
on the wires you intend to manipulate.
Step 4
Ensure
that there is a
short-circuit protection for 3 phases
(breaker or
fuse) before the K-Box not larger than
420 V 65 A
.
Step 5
Put the K-Box on the
DIN rail
of the home distribution box and ensure
the hook is locked properly (

on page 8 for supported rat-
ings and cable diameters.
Step 7

Tighten all clamp screws with enough torque. Insufficient
clamping force can result in high contact resistance that
leads to device heating and can result in a fire hazard.
