40 VDO Face 5™ user manual
AC power
Warning! The safety of the installation is the responsibility of the installer. Read ‘Safety Information’
starting on page 6 before creating an installation or connecting an VDO Face 5™ panel to AC mains
power. Disconnect the entire installation from power before working on it.
Warning! Connect to AC mains power at 100-240 VAC, 50/60 Hz only.
Warning! When you connect VDO Face 5™ panels using power input and throughput connectors to
form one chain that draws power via the first panel’s input connector, you must not exceed a total
current draw of 20 A for the chain. If you do not respect this limit you will overload cables and
components and create a serious safety hazard. If you reach the maximum permitted current draw
for a chain of panels and you want to supply more panels with power, you must create a new chain
that draws power from a separate power outlet.
Warning! For protection from electric shock, the panel must be grounded (earthed). Power
distribution circuits must be fitted with a current overload fuse or circuit breaker with a maximum
rated current of 20 A and ground-fault (earth-fault) protection of high breaking capacity (
≥
1500 A).
Warning! The rubber caps attached to connectors must remain installed at all times on any unused
power and data connectors.
Important! Connect the panels in the installation and the P3 System Controller to AC mains power at
the same outlet point in the power distribution circuit, or you may experience ground/earth loop
problems or create differences in potential that can damage devices. Damage caused by differences
in potential if devices are incorrectly connected to power is not covered by the product warranty.
Voltage range
VDO Face 5™ panels feature an auto-sensing switch-mode power supply that accepts 100-240 V nominal
AC mains power at 50 or 60 Hz. Connect the panel to AC mains power that is within this voltage range only.
The VDO Face 5™ can be supplied with AC mains power by connecting to one of the following three-wire
systems:
• a single-phase 100-240 V system (live, neutral, ground/earth), or
• two phases of a 3-phase delta or split-phase mid-point neutral system (phase, phase, ground/earth) to
obtain 200-240 V
Power figures are given under “Electrical” on page 50. Allow a sensible safety margin when calculating the
current headroom required on AC mains power distribution circuits for an VDO Face 5™ installation.
Power connections
The VDO Face 5™ panel has Neutrik PowerCON TRUE1 connectors for power input and power throughput
to the next panel in a chain.
Power input connectors are located at the bottom of panels and power throughput connectors at the top of
panels (see “Overview” on page 12).
We recommend that you shut down power to the installation before connecting or disconnecting the system
when possible, but if a power shutdown is not possible or difficult, the TRUE1 power connectors used in the
VDO Face system are designed to withstand hot-plugging.
Power plugs and power outlet sockets
A power plug can be installed on the installation’s power input cables to make it easier to connect panels to
AC mains power outlets. If you choose to install a power plug, use an industrial grounding-type (earthed)
3-prong type B plug (see Figure 36) that complies with IEC 60309 or a comparable national standard and is
rated 250 V, 20 A minimum. For outdoor or humid location use, the plug must also be IP67-rated. For indoor
use, the plug may be IP44-rated.
