11.1.9 UL Certification
Figure 11-10 UL/cUL mark
The UL/cUL mark is commonly applied to products in the United States and Canada. It indicates that UL
has performed product tests and evaluations, and determined that their stringent standards for product
safety have been met. For a product to receive UL certification, the main components inside that product
must also be UL certificated.
This series of servo drives have been tested in accordance with UL standard UL508C and comply with
UL standards. Abide by the following requirements to enable machines and devices integrated with this
servo drive to comply with UL standards.
■
Installation location
Install the servo drive in a place with pollution degree 1 or 2 (UL standard).
■
Ambient temperature
Run the servo drive in an ambient temperature not higher than 50° C.
■
Wiring example
See
"3 Wiring"
or the wiring diagram that complies with the Low Voltage Directive.
■
Wiring of main circuit terminals
To meet UL standard, use UL-compliant crimping terminals to crimp the cables on main circuit terminals
with the tools recommended by the terminal manufacturer for crimping. Use crimping terminals with
insulated cladding or insulated sleeves.
Adopt UL-compliant insulated copper cables as main circuit cables, and the continuous maximum
allowable temperature of such cables is 75° C.
Select the cable dimension and tightening torque according to
"3 Wiring"
during wiring.
（Note:
“ “
indicates the grounding terminal defined in IEC/EN60417-5019)
■
Fuse on the input side (primary side)
To prevent accidents caused by short circuit, connect a fuse that complies with UL standards on the
input side. See "Table 11-1 Recommended fuse model" for fuse selection.
See the specifications and model selection of the servo drive for the input and output current of the
servo drive.
See "Table 11-1 Recommended fuse model" for fuse model recommendations.
NOTE
◆
When the fuse burns or the wiring breaker trips, do not switch on the power supply or operate the
machine immediately. Check the wiring and the models of peripherals to identify the cause. If the
cause cannot be identified, contact Inovance. Do not switch on the power supply or operate the
machine without permission before identifying the cause.
◆
Each input cable of the servo drive must be connected to a fuse. When a fuse burns, replace all
the fuses.
