1. Each of the three ground circuits are isolated from each other to
withstand a potential of 500 volts for 1 minute, or 600 volts for 1
second.
2. RSP, Slidewire and the PV inputs are isolated to withstand 50
volts peak between each other for 1 minute.
3. Milliamp, Loop Power and SSR Drive modules in output
positions 1, 2, and 4 are not isolated from each other.
