DISCLAIMER

The Lambda 721 is an ultra-high-speed wavelength switching multi-LED-based beam

combined illumination or light source device. The purpose of the system is to be an

illuminator for microscopes. No other use is recommended.

This instrument is designed for use in a laboratory environment. It is not intended, nor

should it be used in human experimentation or applied to humans in any way. This is not a

medical device.

Unless otherwise indicated in this manual or by Sutter Instrument Technical Support for

reconfiguration, do not open or attempt to repair the instrument.

Do not allow unauthorized and/or untrained operative to use this device.

Any misuse will be the sole responsibility of the user/owner and Sutter Instrument Company

assumes no implied or inferred liability for direct or consequential damages from this

instrument if it is operated or used in any way other than for which it is designed.

SAFETY WARNINGS AND PRECAUTIONS

Electrical

Operate the Lambda 721 using 110 – 240 VAC., 50-60 Hz line voltage. This instrument is

designed for use in a laboratory environment that has low electrical noise and mechanical

vibration. Surge suppression is recommended at all times.

Fuse Replacement: Replace only with the same type and rating:

5 x 20 mm glass tube, Time Lag (IEC 60127-2, Sheet 6)

T3.15A 250V (Time Lag, 3.15 Amps, 250 Volts)

(Littelfuse 02193.15MXAP (219XA Series, RoHS compliant))

A spare fuse is located in the power input module.

Avoiding Electrical Shock and Fire-related Injury

Always use the grounded power supply cord set provided to connect the system’s

power adapter to a grounded/earthed outlet (3-prong). This is required to protect you

from injury in the event that an electrical hazard occurs.

Do not disassemble the system. Refer servicing to qualified personnel.

To prevent fire or shock hazard do not expose the unit to rain or moisture.

Electromagnetic Interference

To comply with FDA and CE/EU electromagnetic immunity and interference standards; and

to reduce the electromagnetic coupling between this and other equipment in your lab always

use the type and length of interconnect cables provided with the unit for the interconnection

of its components (see the Technical Specifications appendix for more details).

Operational

Failure to comply with any of the following precautions may damage this device.

LAMBDA 721 OPERATION MANUAL – REV. 1.10C (20210517)

Operate only in a location where there is a free flow of fresh air on all sides.

NEVER ALLOW THE FREE FLOW OF AIR TO BE RESTRICTED.

This instrument is designed for operation in a laboratory environment (Pollution Degree

I) that is free from mechanical vibrations, and electrical noise and transients.

DO NOT CONNECT OR DISCONNECT THE LQUID LIGHT GUIDE BETWEEN

THE LAMBDA 721 AND MICROSCOPE ADAPTER (OR THE ADAPTER FROM THE

MICROSCOPE) WHILE POWER IS ON.

Operate this instrument only according to the instructions included in this manual.

Do not operate if there is any obvious damage to any part of the instrument.

Do not operate this instrument near flammable materials. The use of any hazardous

materials with this instrument is not recommended and, if undertaken, is done so at the

users’ own risk.

Do not operate if there is any obvious damage to any part of the instrument.

Avoiding Physical Injury while Powered up and Emitting Light

INFRARED AND ULTRAVIOLET RADIATION: Possible infrared and ultraviolet

radiation generated by this lamp can cause significant skin burns and eye damage.

Other

Retain the original packaging for future transport of the instrument.

Sutter Instrument reserves the right to change specifications without prior notice.

This device is intended only for research purposes.

WARNING

DO NOT LOOK DIRECTLY INTO THE OUTPUT OF THE LIGHT

APERTURE MOUNTED ON THE CONTROLLER, THE

CONNECTED LIQUID LIGHT GUIDE, OR THE ATTACHED

MICROSCOPE ADAPTER! Always direct the output of the light

aperture into the microscope using the appropriate adapters,

directed away from anyone’s eyes, and not directed toward any

reflective surface.
