Compliance
‑153‑
● To protect the main circuit, separate and cover the surface that may come into
contact with the main circuit.
● The control circuit is the internal safety extra‑low voltage (SELV) circuit, which
must be insulated and isolated from other circuits. Make sure that the control
circuit is connected to the external SELV circuit.
● Prevent foreign objects from entering the wiring part of the terminal block.
● Avoid welding when using stranded wires.
● The tightening torque may vary with terminals. Tighten terminal screws with the
specified tightening torque. Use screwdrivers, ratchets, or wrenches to tighten
screws as required.
● When using an electric tool to tighten the terminal screws, set the tool to a low
speed to avoid damage to the terminal screws.
● Tighten the terminal screws at an angle within 5 degrees. Failure to comply may
result in screw damage.
Control circuit wiring
Wire the control circuit in accordance with UL508.
Specifications of main circuit cables
For the selection of cable dimensions, follow the requirements of US National
Electrical Code (NEC) and Part 1 of Canadian Electrical Code (CEC) and relevant local
regulations.
● Use cables with copper conductors.
● The recommended cables for the main circuit are 600 V Class 2 heat‑resistant
indoor PVC cables that can work under temperature of 75°C continuously. The
following conditions are used as premises:
■ Ambient temperature: < 40°C
■ Normal operating rating
If the recommended cables for peripheral equipment or options are not suitable for
the product, contact Inovance.

Protective devices
● To meet UL requirements, install a fuse/circuit breaker on the input side to
prevent accidents caused by short circuit in the internal circuit.
● Install sufficient protective devices against short circuit in branch circuits
according to applicable regulations and this guide. The drive is applicable to
circuits with a rated breaking capacity lower than 100000 A and a maximum
