AC power 41
Use corresponding power outlet sockets. Follow the plug and socket manufacturer’s instructions and all
locally applicable laws and electrical safety codes.
When installing a power plug on the power input cable for connection to a single-phase system at 100 - 240
VAC, 50/60 Hz:
• Connect the green/yellow ground (earth) conductor to the terminal marked or for connection to
ground (earth)
• Connect the blue conductor to the terminal marked N for connection to neutral
• Connect the brown conductor to the terminal marked L for connection to live
When installing a plug on the power input cable for connection to two phases of a 3-phase delta or
split-phase mid-point neutral system to obtain 200-240 VAC, 50/60 Hz:
• Connect the green/yellow ground (earth) conductor to the terminal marked or for connection to
ground (earth).
• Connect the blue conductor to the terminal marked N or Phase 1 or L1 for connection to one of the three
phases in the system
• Connect the brown conductor to the terminal marked L or Phase 2 or L2 for connection to another of the
three phases in the system
Table 1 gives details of standard wiring color codes and common pin identification symbols. If you have any
doubts about proper installation, consult a qualified electrician.
Inrush current and earth leakage
The earth leakage current of one VDO Face 5 panel (under normal conditions, i.e. with no live or neutral
fault) is 1.25 mA. The typical half-cycle RMS inrush current of one VDO Face 5 panel (again under normal
conditions, i.e. with no live or neutral fault) is 7.9 A.
When multiple VDO Face 5 panels are connected in a chain on the same power line, the combined ground
(earth) leakage and inrush currents can be high enough to trip the line's residual current circuit breaker
(RCD, RCCB, RCBO) when powering on. The fact that residual current breakers often trip at a significantly
lower ground leakage current than their nominal rating increases the probability that a breaker may trip
unexpectedly. If a breaker trips, substituting with a different breaker may solve the problem. But in some
cases the only solution is to reduce the number of video panels per daisy chain to less than the maximum
permitted number that is specified for the product. To minimize any possible inconvenience, we recommend
that you allow a generous margin when planning number of panels per circuit breaker.
