3.6.1 Relay card connections

DANGER

Electrocution hazard. Relays must either be wired as low or high voltage.

DANGER

Fire hazard: Relay loads must be resistive. User must externally limit current to the

relays to 5 Amps by use of a fuse or breaker.

The relay connector accepts 18–12 AWG wire (as determined by load application). Wire

gauge less than 18 AWG is not recommended.

If the instrument is equipped with the relay card option, the instrument will include 4

relays, each with one change over contact. In this configuration, steps 3, 4 and 6 in To

make a relay card connection are not applicable.

The relays can switch maximum 250 VAC, 5A. Each relay can be configured for different

applications.
