Conditions for UL / CSA Compliant Use

General

If you use the Lexium 62 ILM system in accordance with UL or CSA standards, you must additionally, aside from the installation requirements stated in the present document, meet the following conditions:

Install the “open type equipment” Lexium 62 ILM system at a maximum surrounding air temperature of 40 °C / 55 °C with derating.
Only connect the power supply to a mains supply with a maximum short circuit current of 22 kA or, alternatively, take appropriate measures according to UL508A SB4 in the supply circuit of the control cabinet to limit the short circuit current to 22 kA maximum. This does not apply to operation in accordance with CSA 22.2 No. 14. Here, it is only permissible to operate the device for a maximum short circuit current of 5 kA.
Use devices only in connection with a Lexium 62 Power Supply.
To protect the power supply, use a class J fuse according to UL248 with a maximum fuse rating of 60 A / 600 Vac.
Only use hybrid connection cable approved by Schneider Electric and comply with the requirements of NFPA 79.

Short-Circuit Current Rating (SCCR)

Only connect the Lexium 62 Drive System to a mains supply network not exceeding the non-operational case of SCCR (Short Circuit Current Rating) from following table, or take appropriate measures according to UL 508 A SB4 in the supply (feeder) circuit of the control cabinet to limit the short circuit current to a value below the least SCCR of those devices you are using from the following table.

NOTE: The opening of the branch-circuit protective device (fuses in the case of UL conformance, or any circuit breaker) may be an indication that an invalid condition has been interrupted. To reduce the risk of fire or electric shock, current-carrying parts and other components of the controller must be examined and replaced if damaged. If burnout of the current element of an overload relay occurs, the complete overload relay must be replaced.

DANGER
	FIRE, ELECTRIC SHOCK OR ARC FLASH Examine and replace if necessary any current-carrying parts or other motor control components in the case of mains- or branch-circuit protection activation. Failure to follow these instructions will result in death or serious injury.

According to CSA 22.2 No.14, only a short circuit current rating of 5 kA is permissible.

NOTE: Line reactors according to UL 508 A (SB 4.2.1 Exception No. 1) are not required to have a short-circuit current rating (SCCR).

Notes on Wiring

For the wiring of the Lexium 62 Power Supply, use at least 60 °C (140 °F) / 75 °C (167 °F) copper conductors.
Choose the cross-section according to the load of the system and selected overload protection in your application.

Consider the applicable cross section for the terminal blocks according to following tables:

For Lexium 62 Power Supply

Connection	Torque [Nm] / [lbf in]	Connection cross section [mm²] / [AWG]⁽¹⁾
CN1	2.5 / 22	N/A
CN5	N/A	0.5...16 / 20...6
CN6	N/A	0.75...16 / 18...6
CN7	N/A	0.2...6 / 24...10
CN4	N/A	0.5...1.5 / 20...16
(1) To protect the Lexium 62 Power Supply, use a Class J fuse according to UL 248 with a maximum fuse rating of 60 A / 600 Vac.

DC Bus Coupling

When using the DC bus connection on CN7 of the Lexium 62 Power Supply, ensure that the current is limited to 35 A via this connection with an appropriate fuse or circuit breaker.
