Precautions
•
Only qualified electrical engineer can perform wiring job.
•
To facilitate the input side over-current protection and outage maintenance, connect MONT72 with power supply
via the MCCB or fuse.
•
Do not dismantle MONT72 or do wiring operation until the power is cut-off for more than 10 minutes, the internal
charge indicator of MONT72 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 MONT72 grounding, depending on the operating conditions. To ensure
safety, MONT72 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 MONT72 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 MONT72.
•
For MONT72 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 MONT72.
•
Do not connect the phase-shifting capacitors to the output circuit.
•
Be sure MONT72 has ceased output before switching motor or change-over switches.
•
The MONT72 DC bus terminals must not be short-circuited.

Wiring Specifications of Input and Output
The AC supply to MONT72 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 IEC61800-5-1, as shown in
Table 4-1.
