No condensation, dust, corrosive or flammable gas

Keep distance from high-power electromagnetic devices, contactors and motors

Derate operation when altitude exceeds 1000m

3. Wiring Specifications

Main Circuit Wiring

1. Do not reverse incoming L1/L2/L3 and outgoing U/V/W terminals
2. Separate power cables and control cables with ≥20cm gap, no same conduit laying
3. Reliable earthing, grounding resistance ≤4Ω, ground wire diameter no less than half of phase wire
4. Fasten terminals with proper torque to prevent loose connection and overheating

Control Circuit Wiring

1. Use shielded twisted pair for analog and communication cables, single-end shielding grounding
2. Avoid routing signal cables close to power lines
3. Prevent polarity reversal of external 24V power supply
4. Heat Dissipation & Ventilation
5. Keep cabinet door ventilated, clean filter screen regularly
6. Equip cooling fan for smooth air circulation
7. Avoid direct sunlight on the device
8. EMC & Anti-interference Protection
9. Built-in EMC filter works only with complete grounding
10. Motor cable length recommended ≤50m; install output reactor for long cables
11. Do not coil or twist input and output wires
12. Freewheel diodes parallel connected to peripheral relays and solenoid valves
13. Brake Accessory Installation

Built-in brake transistor matched with external brake resistor

1. Use 75Ω/500W resistor, mount in well-ventilated area
