Manufactured by Cleaver Scientific 
2907.1 

 

 

WARNING: 

Please read the entire operator’s manual thoroughly before operating this unit. 

 
 

Warning: 

Like all apparatus run by electricity these units are capable of delivering potentially lethal voltage. 
They should be operated only by qualified technically trained personnel. The Roth power supplies are 
designed for long term laboratory use and to obtain reproducible results. Please spend a few 
moments reading the instruction manual thoroughly. 

The Roth power supply series has been tested and found to comply with the limits for the CE 
regulation. Also, it is RoHS compliant to deliver confident product which meets the environmental 
directive.

 

These limits are designed to provide reasonable protection against harmful interference 

when the instrument series is operated in a commercial environment. This power supply series 
generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance 
with the instruction manual, may cause harmful interference to radio communications. Operation of 
this power supply series in a residential area is likely to cause harmful interference in which case the 
user will be required to correct the interference at their expense. Changes or modifications not 
expressly approved by the party responsible for compliance could void the user’s authority to operate 
the equipment. It is strongly recommended for the user to read the following points carefully before

1.

 

Read and follow the manual instructions carefully. 

2.

 

Do not alter the equipment. Failure to follow these directions could result in personal and/ or 
laboratory hazards, as well as invalidate the equipment warranty. 

3.

 

Use a properly grounded electrical outlet of correct voltage and current handling capacity. 

4.

 

Disconnect from the power source before maintenance and servicing. Refer servicing to qualified 
personnel. 

5.

 

Never use this instrument without having the safety cover correctly in position. 

6.

 

Do not use the unit if here is any sign of damage to the external tank or cover. Replace damaged 
parts. 

7.

 

Do not use in the presence of flammable or combustible material as fire or explosion may result. 
This device contains components, which may ignite such materials. 

8.

 

Refer maintenance and servicing to qualified personnel. 

9.

 

Ensure that the system is connected to the electrical source according to the local and national 
electrical codes. Failure to make a proper connection may create a fire or shock hazard. 

10.

 

Use appropriate materials and operate correctly to avoid possible hazards of explosion, 
implosion or release of toxic or flammable gases arising from overheated materials. 

11.

 

The unit shall be operated only by qualified personnel.
