▪ To punch a knockout hole, hit on it with a hammer.
▪ After knocking out the holes, we recommend removing any burrs and paint the
edges and areas around the holes using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout holes. prevent damage to
the wires by wrapping the wiring with protective tape, putting the wires through
field supplied protective wire conduits at that location, or install suitable field
supplied wire nipples or rubber bushings into the knockout holes.

knockout holes, close the holes with packing materials (to be prepared on-site)
This equipment complies with:
▪ EN/IEC 61000‑3‑11 provided that the system impedance Z
to Z at the interface point between the user's supply and the public system.
max
- EN/IEC 61000‑3‑11 = European/International Technical Standard setting the
limits for voltage changes, voltage fluctuations and flicker in public low-voltage
supply systems for equipment with rated current ≤75 A.
- It is the responsibility of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a system impedance Z
or equal to Z .

▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
equal to the minimum S
and the public system.
- EN/IEC 61000‑3‑12 = European/International Technical Standard setting the
limits for harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and ≤75 A per phase.
- It is the responsibility of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a short-circuit power S
than or equal to the minimum S
