CSIP Level 1 Troubleshooting: Power Input Requirements
Power Input
Requirements
WARNING For safety and liability reasons, do not disassemble any power outlet or open any electrical panel.
Have the facility representative confirm wiring compliance with the criteria specified below.
➤ To determine if the site meets electrical power requirements
1. Explain to the facilities representative that the system requires a dedicated and isolated line
meeting the power requirements as listed in Ta bl e 9- 1.
2. Verify the outlet to be used is a dedicated and isolated line:
a. Have the facility representative open the circuit breaker.
b. With a DVM or three-wire test plug, confirm that power is still applied to all other out-
lets and hard-wired devices in the immediate area and that power is removed only from
the dedicated and isolated outlet box.
3. Verify the proper wiring of the outlet using a three-wire test plug. This plug also tests for the
presence of a ground, but it cannot detect neutral/ground reversals.
4. Inform the facility representative of the current draw of the system and its acceptable voltage
range. It is the responsibility of the facility representative to determine the proper size of the
wire based upon the length of the feed.
5. Using your DVM at the outlet, measure the hot/neutral, hot/ground, and neutral/ground volt-
ages with a comparable load (for example, another ultrasound system) on the line.
