Equipment shall be mounted on pre‑embedded base frame with strict flatness & perpendicularity tolerances; proper earthing for base frame and whole cubicle array is mandatory, and distribution‑room ceiling height must satisfy minimum dimension requirement. Please contact us for foundation‑spec‑checklist.
All installation, operation and maintenance activities must be completed by professional electrical engineers; relevant local power‑utility safety procedures shall be strictly followed before any work inside live compartments. Please contact us for on‑site‑safety‑guidance.
Mechanical interlock prevents inserting or removing drawers under closed‑breaker status; drawers can only be operated with breaker at open position, and supports padlock‑locking to avoid unauthorized live‑zone operations. Please contact us for interlock‑logic reference.
