The surface of the control box shade is uncoated. Can be installed by tightening to the mounting tabs on the control box. Control box shade cannot be installed later. Specify shade at time of order. OPERATING INSTRUCTIONS Installation Area Determine the operating current so that the total heat value of 1 wire bundle is below 300 [A2 × wires]. Also, when calculating the heat value, take the current fluctuation (10%) into consideration. [calculation example: EC2B-41**B (8 circuit)] ➀ Apply 10A to 1 circuit, 1A to the remaining 7 circuits: {(10A × 1.1)2 × 2 wires} + {(1A ×1.1)2 × 14 wires} ≈ 259 (can be used because < 300) ➁ Apply 10A to 1 circuit, 2A to the remaining 7 circuits: {(10A × 1.1)2 × 2 wires} + {(2A × 1.1)2× 14 wires} ≈ 310 (cannot be used because > 300) See the table below for the allowable operating current when applying current evenly to each control box. Do not install the EC2B control box in an environment where more than IP65 protection degree (more than Type 4X in North America) is required. Use the EC2B control box under ambient temperature of –20 to +50°C. If the control box is exposed to direct sunlight and the surface temperature may rise above 50°C, provide a shade to keep the surface temperature below 50°C. Installation Use four M6 bolts for 1-column, four M8 bolts for 2- and 3-column, or other methods with equivalent strength to install the control box. Mounting tab thickness is 1.5mm for 1 column and 2mm for 2, 3, and 4 columns. • If bolts become may loose due to vibration, use spring washers. • If bolt corrosion is anticipated, use anti-corrosion bolts or other countermeasures. Allowable Operating Current Notes on Emergency Stop Switches When using the emergency stop switches on safety-related parts of the control system, observe safety standards and regulations of the relevant country or region. Also be sure to perform a risk assessment before operation. Opening/Closing the Lid Use a Philips screwdriver to loosen lid mounting screws. While holding the unhinged side, open the lid slowly without exerting excessive force on the hinge. Before closing the lid, make sure of the following: • No foreign substances are on the packing or joint surfaces. • No displacement of the waterproof packing. • Wires are not caught between the joint surfaces. • Next, close the lid slowly and tighten the screws to a proper torque of 1.6 to 2.4 N·m. Limitation of the Operating Current Major heat sources comes from the wiring which is connected to the control box. Therefore, not only the operating current but wiring conditions (size, no. of wires, no. of wire bundles) may cause temperature rise. When wiring, observe the following conditions. Stranded wire: 1.5 to 2.5 mm2 (UL-c-UL certified) / Solid wire: ø1.2 to ø1.6 mm (16 to 14 AWG) • Maximum no. of wires per bundle: 16 • Maximum operating current: 10A When using the control box under an operating environment of 40°C minimum, use a heat resistant cable of 70°C minimum.
