２．Compliance with UL Standard
The VF-P7 models conform to the UL Standard have the UL/CUL mark on the nameplate.
2.1. Compliance with Installation
The VF-P7 Inverter must be installed in a panel, and used within the maximum surrounding air
temperature 50 degrees.
2.2. Compliance with Connection
Use the UL listed cables, 75 degree copper wire only, with the UL listed closed -loop
terminal connector at field wiring connection to the inverter input terminals, R/L1, S/L2,
T/L3, output terminals, U/T1, V/T2, W/T3, and other main terminals.
Refer the wire gauge, the type of closed-loop terminals and crimping tools to Table.4
and Table.5.
2.3. Compliance with Peripheral devices
Use the UL listed MCCB or fuses at connecting to power supply.
(The fuses should be used CLASS CC/J.)
Refer to the instruction manual about selecting the rating of them.
Short circuit test is performed under the condition of the power supply
short-circuit currents in Table. 3.
These currents depend on the applicable motor capacities.
