SAFETY INFORMATION
Take all necessary precautions for using any electrical device. Before connecting the electrical supply,
check to see if the supply voltage is within the range stated at the rating label, and see to it that the
device be seated firmly. Place the unit in a safe and dry; it must NOT touch the surrounding. Follow
the safety precautions for chemicals and dangerous materials. If needed, please contact us at Tel.:
0721/5606-0.
Environmental Conditions
Ensure the instrument is installed and operated strictly under the following conditions:
• Indoor use only
• RH ≤95 %
• 75 KPa-106 kPa
• Altitude not to exceed 2000 meters
• 4 °C ~ 40 °C operating temperature
• Pollution degree: 2
• Mains supply voltage fluctuations up to ± 10 % of the normal voltage
Avoiding Electrical Shock
Follow the guidelines below to ensure safe operation of the unit.
The Roth power supply series has been designed for use with insulated wires, minimizing any
potential shock hazard to the user. We recommend against the use of uninsulated wires.
To avoid electrical shock:
1. In case of spillage, any parts of the cable or power supply must be dried out for a period of time and
restored to NORMAL CONDITION before the operation.
2. NEVER connect or disconnect wire leads from the power jacks when the red indicator light of the
power switch is on.
3. WAIT at least 5 seconds after stopping a run before handling output leads or connected apparatus.
4. ALWAYS make sure that your hands, work area, and instruments are clean and dry before making
any connections or operating the power supply.
5. ONLY connect the power cord to a properly grounded AC outlet.
Avoiding Damage to the Instrument
1. Do not attempt to operate the device if damage is suspected.
2. Protect this unit from physical damage, corrosive agents and extreme temperatures (direct sunlight
etc).
3. For proper ventilation and safety concerns, keep at least 10 cm of space behind the instrument, and
at least 5 cm of space on each side.
4. Use high level of precaution against damaging the unit.
5. Do not operate the unit out of environmental conditions addressed above.
6. Do not operate the power supply in high humidity environments (> 95%), or where condensation
may occur.
7. To avoid condensation after operating the power supply in a cold room, wrap the unit in a plastic
bag and allow at least 2 hours for the unit to equilibrate to room temperature before removing the
bag and operating the unit.
8. Prior to applying any cleaning or decontamination methods other than manufacturer’s
recommendation, users should check with the manufacturer’s instruction to see if the proposed
method will damage the equipment.
Maintenance
The ROTH power supplies require little maintenance to ensure reliable operation. The housing may
be cleaned with a dry cloth.
