Installation specifications and size requirements

1. Installation method and steps

(1) DIN rail installation (DIN EN 50022, 35 × 7.5mm rail)

Installation steps: ① Push the device in and press down to clamp the top rail hook into the rail; ② Rotate the bottom of the device towards the guide rail; ③ The guide rail buckle will "click" to fasten. If it is not fastened, check whether the guide rail is bent; ④ The heat sink must be installed vertically (core requirement to ensure heat dissipation efficiency) 🔶 1-223 🔶 1-224 🔶 1-225.

Disassembly steps: Press and release the buckle, while rotating the device upwards and away from the guide rail to remove it.

Spacing requirement: A 102mm (4.0 inches) gap should be reserved on the side for airflow and wire bending radius; The front is designed with anti touch features, requiring no additional clearance; Minimum snap distance 34.8mm (1.37 inches), maximum 35.3mm (1.39 inches) 🔶 1-236 🔶 1-245.

(2) Panel installation

Four M4 (# 8) fasteners are required for fixation. Please refer to the panel installation dimension diagram on page 7 of the manual for specific dimensions, with a focus on the grounding wire entry position (13mm/0.50 inches) and the parallel arrangement wire gap (83mm/3.25 inches).

(3) Wall through installation (UL) ®  50 Type 4X Shell Model

Additional materials: 1 silicone gasket, 8 M5 screws and locking washers, 1 DIN-A-MITE C wall penetrating device 🔶 1-253 🔶 1-254 🔶 1-255.

Installation steps: ① Drill holes and cut the panel according to the size diagram on the right; ② Remove the mounting screws from the heat sink; ③ Tear off the protective film of the silicone gasket, attach the gasket to the heat sink, and ensure that the gasket hole is aligned with the heat sink screw hole; ④ Vertically install heat sink, torque controlled at 2.26-2.82 Nm (20-25 inch pounds) 🔶 1-257 🔶 1-258 🔶 1-259.

Size and Gap: The panel opening should meet the contour requirements of 178mm (7.00 inches) × 122mm (4.81 inches), and a minimum gap of 102mm (4.0 inches) should be reserved above and below the heat sink for airflow. A minimum gap of 10mm (0.4 inches) should be reserved on both sides.

2. Requirements for wiring terminals

(1) Input terminal (control signal type)

Adopting a crimping design, compatible with 0.2-1.5mm ² (24-16 AWG) wires; Use a 3.5mm (1/8 inch) flathead screwdriver and tighten to a torque of 0.5 Nm (4.4 inch pounds); The stripping length of the wire is 5.5mm (0.22 inches); The insulation level of the wire must be ≥ 75 ° C and is only applicable to copper conductors 🔶 1-61 🔶 1-62 🔶 1-63 🔶 1-64.

(2) Main circuit terminals (phase line, load, grounding)

Also of crimping type, compatible with 2.5-25mm ² (14-3 AWG) wires; Can be tightened with a 6.4mm (1/4 inch) flathead screwdriver or a 1A type # 2 Pozidriv screwdriver to a torque of 2.7 Nm (24 inch pounds); Wire stripping length 11mm (7/16 inches); Core maintenance requirement: Re tighten after 48 hours (to reduce wire cold flow), and then re tighten every 3-6 months thereafter 🔶 1-66 🔶 1-67 🔶 1-68 🔶 1-69 🔶 1-70.

(3) Cooling fan terminal

Adopting a quick connect design (1/8 inch push in), compatible with 16-14 AWG wires; Recommend using Amp part number 640929-1 or equivalent product 🔶 1-85.

Control mode and signal configuration

1. Zero crossing control mode (including contactor and proportional control)

(1) Type of contactor (input control signal)

DC input (Type C): 4.5-32V (DC) input, with a maximum current of 6mA per channel at 4.5V. An additional 2mA total current is required for each additional LED; To extend the service life, the cycle time should be less than 3 seconds 🔶 1-94.
