AC power
WARNING! The safety of the installation is the responsibility of the installer. Read "Safety
Information" on page 4 before creating an installation or connecting an EC Series panel to AC mains
power. Disconnect the entire installation from power before carrying out installation work.
WARNING! Connect to 200-240 VAC, 50/60 Hz mains power only.
WARNING! A maximum of sixteen EC Series panels in total may be interconnected using power
input and throughput connectors to form one chain that draws power via the first panel's input
connector. If you do not respect these limits you will overload cables and components and create a
serious safety hazard. If you reach the maximum permitted number of interconnected panels in one
chain and 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 40A for European region and with a maximum rated current of 32A for North
American region) and ground-fault (earth-fault) protection of high breaking capacity (
WARNING! EC Series panels do not have a power on/off switch. They are powered on as soon as
mains power is applied to the power input connector and remain powered on until mains power is
shut down at source or disconnected. The external power switch or power outlet socket must be
located near the panels and easily accessible so that power to the panels can easily be shut down or
disconnected if necessary.
WARNING! Two-pole/neutral fusing.
WARNING! The supplied rubber caps must remain installed at all times on any unused power and
data throughput connectors. Keep unused caps safely for re-installation as soon as a video wall is
disassembled.
WARNING! Protect the power cables on the headers from water and rain.
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
EC Series panels feature an auto-sensing switch-mode power supply that accepts 200-240 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 EC Series can be supplied with AC mains power by connecting to one of the following three-wire
systems:
• a single-phase 200-240 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 28. Allow a sensible safety margin when calculating the
current headroom required on AC mains power distribution circuits for an EC Series installation.
Power connections
Power input
The EC Series Header is supplied with a 1 m (3 ft. 3 in.) hard-wired power input cable (see A in Figure 2 on
page 9). Protect this cable from rain. If necessary, lengthen with an appropriate cable according to local
building and electrical codes.
Power is relayed from a Header to a panel via the output socket: this is the same type of socket as the
throughput socket of a panel.
