Chapter 4 Electrical Installation
4.1 Precautions
• Only qualified electrical engineer can perform wiring job.
• To facilitate the input side overcurrent protection and outage maintenance, connect controller with power supply
via the MCCB or fuse.
• Do not dismantle controller or do wiring operation until the power is cut-off for more than 10 minutes, the
internal charge indicator of controller is off and the voltage between (+) and (-) of the main circuit terminals is
below 36V.
• Check the wiring carefully before connecting emergency stop or safety circuit.
• There is more than 3mA leakage current in HD5L-PLUS grounding, depending on the operating conditions. To
ensure safety, controller and the motor must connect to separate and independent grounding wire, so as to
ground reliably. It must use Type B mode when utilize ground leakage protection devices (ELCB/RCD).
• Do not touch the wire terminals of controller when it is live. The main circuit terminals are neither allowed
connecting to the enclosure nor short-circuiting.
• Do not do dielectric strength test on controller.
• For controller with more than 2 year’s storage, please use regulator to power it slowly.
• Do wiring connection of the braking resistor or the braking unit according to the wiring figure.
• Make sure the terminals are fixed tightly.
• Do not connect the AC supply cable to the output terminals U/V/W of controller.
• Do not connect the phase-shifting capacitors to the output circuit.
• Be sure controller has ceased output before switching motor or change-over switches.
• The controller DC bus terminals must not be short-circuited.
4.2 Peripheral Accessories Selection
4.2.1 Wiring Specifications of Input and Output
The AC supply to HD5L-PLUS must be installed with suitable protection against overload and short-
circuits, i.e. MCCB (molded case circuit breaker) or equivalent device.
The recommended specification of MCCB, contactor&cables are shown as Table 4-2.
The size of ground wire should accord with the requirement in 4.3.5.4 of IEC 61800-5-1, as shown in
Table 4-1.
