Installation / Setup
The installation/setup highlights for the 2734A Direct Voltage Reference Bank include the following:
1. Unpacking: If the shipping carton is damaged, ensure the carrier’s agent is present during unpacking. If damage is found, notify the carrier’s agent for repair authorization before returning the unit to Valhalla Scientific.
2. Initial Adjustments: Before operation, select the correct local power source voltage and verify the correct fuse is fitted. The supply voltages and corresponding fuses are:
– 105 to 128VAC 50/60Hz with a 1 Amp Slo Blo Fuse
– 210 to 256VAC 50/60Hz with a 0.5 Amp Slo Blo Fuse
3. Bench Use: The unit is ready for bench use without special instructions. Ensure the power cord has a three-terminal connector.
4. Rack Mounting: Optional brackets are available for 19″ rack mounting. The unit should be supported on both sides to prevent movement during transport. Allow sufficient airflow by placing 1.75″ high blank panels above and below the unit in the rack. Avoid ambient temperatures above 50°C during operation or 70°C when not in use.
5. Safety Precautions: Use a three-contact power connector with a continuous ground connection to ensure safety.
