Installation and wiring specifications

(1) Installation requirements

Installation foundation: It must be installed on a metal plate, and the rear panel should not be installed on flammable materials due to high temperature

Installation space: For single unit installation, a space of 10cm up and down, and 5cm left and right should be reserved; Multiple units installed side by side need to reserve a gap of ≥ 11mm, and capacity reduction is required in environments above 50 ° C or when installed side by side

Handling specifications: Models weighing over 20kg require 2 people to handle, VFAS3-6300PC~6750PC require a crane to handle, and it is forbidden to grip the front cover for handling

Peripheral equipment: Short circuit protection devices (such as MCCB, ELCB) and emergency stop devices must be installed, and thermal relays are required (when multiple motors are shared, each motor is separately configured)

(2) Wiring specifications

Core principle: Power must be disconnected before wiring, wait for at least 15 minutes, confirm that the charging light is off and the DC main circuit voltage is ≤ 45V before operation

Wiring requirements:

Power wiring: Connect a 3-phase power supply to the [R/L1], [S/L2], and [T/L3] terminals, with voltage fluctuations within ± 10% (± 10% during continuous operation at full load)

Motor wiring: Connect to [U/T1], [V/T2], [W/T3] terminals, and it is strictly prohibited to connect the power supply to the output terminal

Grounding requirements: The grounding wire should be firmly connected, with specifications not lower than the input/output wire, and should be grounded separately and not shared with the chassis screws

Braking resistor: can only be connected to [PA/+] and [PB] terminals, and it is strictly prohibited to connect between [PA/+] and [PC/-]
