5. Matches complete lineup of KOLLMORGEN Zone 2 certified explosion-proof servo motors without additional safety interface modules
6. Surge suppressed dynamic braking circuit removes transient voltage ignition sources during high inertia deceleration
7. Factory locked safety-certified firmware prevents unauthorized modification that would invalidate hazardous area certification

Applicable Industries

Installation Requirements

1. Install exclusively inside IEC certified Zone 2 explosion-proof metal control cabinet, vertical DIN rail fixed
2. Maintain minimum 50 mm vertical radiator clearance above and below drive unit for convection cooling
3. Use only certified explosion-proof cable glands for all wiring entry into classified cabinet housing
4. Separate high-voltage power cables and isolated low-voltage signal cables in independent sealed cable conduits
5. Cabinet grounding copper wire cross-section ≥4 mm², grounding resistance strictly controlled ≤3 Ω
6. Mandatory cabinet internal forced cooling fan to maintain internal temperature below 40 ℃ continuous operation

Usage Precautions

1. Cut mains power supply and wait 10-minute DC bus discharge period before opening cabinet wiring terminals in hazardous zones
2. Do not substitute non-certified braking resistors, encoder cables or communication wiring; safety certification will be voided
3. Regularly inspect internal conformal coating integrity every 6 calendar months for chemical vapor degradation
4. Prohibit removal of front indicator dust-proof cover in classified production environments
5. Any disassembly of internal isolation circuits or power modules invalidates all explosion-proof certification and factory warranty
6. Do not store or operate unit in environments exceeding certified T4 temperature class rating
