Prevent Possible Unintended Operation and Avoid Overvoltage

The following measures avoid overvoltages and help prevent possible unintended equipment operation through conductive pollution or parts falling into the device:

DANGER
	ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Install Lexium 62 in a control cabinet or housing with a minimum IP 54 rating. Comply with the clearances and creepage distances according to EN 50178. Lexium 62 must only be operated with 24 Vdc power supplies certified according to EN 60950 or EN 50178. Failure to follow these instructions will result in death or serious injury.

NOTE: These power supply units do not deliver an overvoltage over 120 Vdc for more than 120 ms or no permanent overvoltage over 60 Vdc.

Only operate the drive system with approved, specified cables, accessories and replacement equipment by Schneider Electric.

DANGER
	ELECTRIC SHOCK OR ARC FLASH Do not use non-Schneider Electric approved cables, accessories or any type of replacement equipment. Failure to follow these instructions will result in death or serious injury.

Avoid Unintentional Restart

The unintentional restart of the equipment must be avoided by appropriate means, depending on your particular application.

DANGER
	UNINTENTIONAL RESTART OF THE MOTOR Ensure that a restart of the motor is not possible after a return of power or the tripping of a functional safety device unless preceded by a deliberate enable signal from the system. Ensure that the enable signal meets the specified safety criteria. Failure to follow these instructions will result in death or serious injury.

Encoder Connection When Using Extended Safety-Related Functions

Lexium 62 variants E/F enable the use of extended, position-dependent and/or velocity-dependent safety-related functions. Among other things, these safety-related functions require encoder signals. The use of third-party encoders may present a degradation or loss of the safety functions.

DANGER
	INOPERABLE SAFETY FUNCTION Use synchronous motors only. Use the encoder signals that are also used for the drive control of the synchronous motors. Only use SinCos encoders according to the requirements and assumptions of IEC 61800-5-2. Failure to follow these instructions will result in death or serious injury.
