Laser Classification

Class 1 laser product; Complies with IEC 60825-1:2001 and 21 CFR

1040.10, except for deviations pursuant to Laser Notice 50, dated

7-26-01

Environmental Ratings

IEC IP67; NEMA 6; UL Type 1

Required Overcurrent Protection

WARNING: Electrical connections must be

made by qualified personnel in accordance

with local and national electrical codes and

regulations.

Overcurrent protection is required to be provided by end product

application per the supplied table.

Overcurrent protection may be provided with external fusing or via

Current Limiting, Class 2 Power Supply.

Supply wiring leads < 24 AWG shall not be spliced.
