WAGO-I/O-SYSTEM 750 Programmable Fieldbus Controller ETHERNET 

Impact resistance 1000g (1ms) 500g (1ms)

(2) Selection criteria

According to load requirements: If the current of the connected equipment is ≥ 10A and the voltage is ≥ 600V (such as heavy-duty motors and wind power control cabinets), priority should be given to selecting the heavy-duty connector (RS-HD120); If it is a light load (such as PLC module, small controller, current ≤ 10A), choose a regular rectangular connector (RS-6536);

According to environmental conditions: If the ambient temperature is ≥ 105 ° C or there is strong impact (such as rail transit vehicles, mining machinery), choose heavy-duty connectors (PC shell+high impact resistance); If it is a conventional industrial environment (temperature ≤ 105 ° C, no strong impact), choose a regular rectangular connector;

According to the number of cores required: If the number of connected cores is ≥ 48 (such as heavy-duty equipment with multiple signal integration), select heavy-duty connectors (double-layer structure); If the number of cores is ≤ 48, choose a regular rectangular connector (single-layer structure, lower cost).

Question 3: In outdoor photovoltaic inverter wiring scenarios, it is necessary to choose RS Pro cable management products (including protective hoses, zip ties, and labels) that meet the requirements of UV resistance, temperature resistance -30...+100 ° C, and IP68 protection. Which specific products should be selected? And explain the reasons for the selection.

Answer:

(1) Specific product selection

Product Category Recommended Model Core Parameters Selection Reasons

Cable protection hose RS-PA16 material PA, inner diameter 16mm, temperature resistance -40...+125 ° C, UV resistance (UV stable), protection IP68. 1. PA material temperature resistance covering -30...+100 ° C scenarios, and UV resistance (long-term outdoor use without aging); 2. 16mm inner diameter suitable for commonly used 10mm ² cables in photovoltaic inverters; 3. IP68 protection can prevent rainwater immersion

Cable tie RS-FR48 material nylon 66 (UL94 V0), width 4.8mm, length 300mm, temperature resistance -40...+105 ° C, UV resistance 1. Temperature resistance -40...+105 ° C, covering scene requirements, UV resistance to avoid outdoor brittleness; 2. Width 4.8mm, tensile strength ≥ 120N, can fix multiple cables; 3. Flame retardant grade UL94 V0, suitable for fire protection requirements of photovoltaic equipment

Cable identification RS-PL30 material plastic, size 30 × 15mm, temperature resistance -20...+80 ° C, UV resistance, waterproof 1. Plastic material UV resistance, waterproof, outdoor identification clear and non fading; 2. The size of 30 × 15mm can be labeled with cable numbers (such as "PV-01"), suitable for multi circuit identification requirements of photovoltaic inverters; 3. Temperature resistance -20...+80 ° C, covering most outdoor environments (extreme low temperatures can be additionally wrapped with insulation layer)

(2) Supporting suggestions

Can be paired with RS-PA16 hose specific threaded connectors (M16 specification, IP68 protection) to seal the hose and inverter housing, further enhancing the overall protection level; At the same time, choose adhesive fixed seats (made of PA66 material and 3M UV resistant adhesive) to fix the zip ties without drilling holes, avoiding damage to the anti-corrosion layer of the inverter casing.
