Compliance
‑172‑
● Prevent foreign matters from entering the wiring part of the terminal block.
● Do not carry out welding when using twisted conductors.
● Tightening torque of terminals may vary. Tighten the screws with corresponding
tightening torque. Torque screwdriver, ratchet, or wrench can be used.
● If an electric tool is used to tighten the terminal screws, use a low speed setting to
avoid damage to the terminal screws.
● Tighten the terminal screws at an angle within 5 degrees. Failure to comply may
damage terminal screws.
Control circuit wiring requirements
Wire the control circuit in accordance with UL508.
Cable selection requirements for the main circuit
For the selection of wire 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.
● For the main circuit, use Class 2 heat‑resistant indoor PVC cables rated 600 V, with
a continuous maximum allowable temperature of 75 °C. The following conditions
are used as premises:
1. Ambient temperature: < 40°C
2. Normal operating ratings
If the recommended cables for peripheral equipment or options are not suitable for
the product, contact Inovance.

Requirements on protective devices
● To meet UL requirements, install a fuse and circuit breaker on the input side to
prevent accidents caused by internal short circuit.
● Install adequate branch circuits for short circuit protection in accordance with
applicable regulations and the requirements in this user guide. The product is
applicable to circuits with maximum rated breaking capacity of 100,000 A and
maximum voltage of 480 VAC (400 V class). For selection of recommended fuses,
