2.7.1
AC Power Connection
Phase conductor should be applied to terminal 1, neutral conductor to terminal 2 in each of the supply
terminals identified as Power 1 and Power 2 as shown in
Figure 8: AC power connection
For compliance with IEC 61010, install a suitable external switch or circuit breaker in each current-carrying
conductor of RT430 power supply; this devccccice should interrupt both the hot (+/L) and neutral (-/N) power
leads. An external 10 A, category C, bipolar circuit-breaker is recommended. The circuit breaker should have
an interruption capacity of at least 25 kA and comply with IEC 60947-2. The switch or circuit-breaker must be
suitably located and easily reachable, also it shall not interrupt the protective earth conductor.
2.7.2
DC Power Connection
Positive should be applied to terminal 1, negative to terminal 2 in each of the supply terminals identified as
Power 1 and Power 2 as shown in
Figure 9: DC power connection
