Fire hazard. Relay loads must be resistive. Always limit current to the relays with an external fuse or
breaker. Obey the relay ratings in the Specifications section.
Fire and electrical shock hazard. Obey relay load limitations of the external circuits specified in the
Specifications section. The circuit application will determine the wire gauge needed; however, wire
gauge less than 18 AWG is not recommended.
The analyzer contains:
• Five output relays (S1–S5)—single-pole changeover relays with volt-free contacts
• One input relay (SW1)—normally open contact relay with volt-free contacts
Use the relays at either all high voltage (greater than 30 V-RMS and 42.2 V-PEAK or 60 VDC) or all
low voltage (less than 30 V-RMS and 42.2 V-PEAK, or less than 60 VDC). Do not configure a
combination of both high and low voltage.
Use the output relays to output the status of the analyzer.
Use the input relay to remotely control the analyzer (e.g., stop measurements or start an auto
calibration).
