WARNING! The safety of the installation is the responsibility of the installer. Read “Safety
Information” on page 3 before creating an installation or connecting an EC-20 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-20 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 (
≥ 1500 A).
WARNING! EC-20 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 EC-20 and easily accessible so that power to the EC-20 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
The EC-20 features 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-20 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 “Power through Integral” on page 27. Allow a sensible safety margin when
calculating the current headroom required on AC mains power distribution circuits for an EC-20 installation.
Power connections
Power input
The EC-20 Header is supplied with a 1 m (3 ft. 3 in.) hard-wired power input cable (see A in Figure 2 on
page 8). 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 socket as the throughput
socket of a Panel.

18 EC-20 user manual
Panel interconnection
Power input and throughput connectors on EC-20 panels are integral and engage automatically when
panels are installed in columns (see Figure 9 on page 12).
Power is supplied to columns of panels via the Header power input cable (see A in Figure 2 on page 8).
Power is relayed from the Header to the first EC-20 panel and then from one panel to the next via power
throughput connectors (see A, Band C in Figure 17) and input connectors (see E, Gand H in Figure 17).
Do not power panels on or off by inserting or removing live power connectors or plugs, as this will cause
arcing at the connector contacts that may damage devices and connectors.
Power plugs and power outlet sockets
A power plug can be installed on the Header’s power input cable to make it easier to connect panels to AC
mains power outlets. Install an industrial grounding-type (earthed) 3-prong type B plug (see Figure 18) that
complies with IEC 60309 or a comparable national standard and is rated 240 V, 32 A minimum. For outdoor
or humid location use, the plug must also be IP67-rated. For indoor use, the plug may be IP44-rated.
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 Header’s power input cable for connection to a single-phase system at
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 Nfor connection to neutral
• Connect the brown conductor to the terminal marked Lfor connection to live
When installing a plug on the Header’s 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

doubts about proper installation, consult a qualified electrician.
Inrush current
Inrush current peaks are unlikely to occur at exactly the same time in multiple panel installations and only
have a duration of a few microseconds, but bear in mind that inrush current when powering on may cause
unintentional tripping of circuit-breakers, especially if these have low resistance to momentary current
peaks.
Fuses
WARNING! Fuses are not user-replaceable and must be replaced by Martin or its authorized service
agents.
WARNING! Double pole / neutral fusing.
Each EC-20 panel is protected by two 3.15 amp slow-blow mains fuses. The breaking capacity is 1500 A @
250 V. Fuses are not user-replaceable. Contact Martin for service if you suspect that a fuse has blown.

P3 communication link
EC-20 series panels communicate using the Martin™ P3™ signal format (Ethernet Martin™ P3™
Protocol). The P3 signal contains both video data and command signals.
The Header has an integral data input tail and throughput connector, and EC-20 panels have integral P3
data input and throughput connectors (see Dand Fin Figure 17 on page 18). P3 data is therefore
connected automatically when panels are fastened together in a vertical column.
Cable and connector types
Use good-quality CAT 5e or better STP (shielded twisted pair) Ethernet cable for the P3 link to the Header.
RJ-45 connectors should be shielded type, with the shield around the connector terminals electrically
connected to the cable shield.
The Ethernet socket on the Header is mounted in an Amphenol IP67-rated reverse bayonet-mount housing.
RJ-45 plugs installed in Amphenol RJF RB 6 housings (as supplied with the Headers) or in an indoor
environment non-IP-rated standard RJ-45 Ethernet connectors and patch cables may be used as
connectors on the link.
All unused connectors must be sealed with their supplied rubber caps at all times.
Suitable IP67-rated and non IP-rated patch cables in various lengths and suitable connector housings are
available from Martin (see “Accessories” on page 28).
Planning the P3 link
Figure 19 on page 21 shows an example of P3 system layout.
Media source
P3-100 controllers accept the following video signal types:
• Composite video (CVBS)
•S-video
• Component video
•DVI-D
If you intend to use a media server, we recommend the use of a product from the Martin™ Maxedia™
series. Maxedia products offer fast processors, advanced features, DVI output and an intuitive user
interface.
P3 link requirements in large installations
A single P3-100 system controller can drive up to 500 000 pixels, corresponding to maximum of 578 EC-20
panels, provided that Ethernet switches are used to split and/or amplify the P3 signal as described in this
section. If an installation consists of more panels, it can be split into two and two P3-100 controllers used in
tandem.
Using Ethernet switches to split the link into chains
See Figure 19. If the EC-20 installation consists of more than one column of panels, you must first run the
P3 signal output from the P3-100 System Controller to a 1 GB Ethernet switch. then use the outputs from
the Ethernet switch to send the P3 signal to each column of panels.
Using Ethernet switches to extend the link
See Figure 19. The maximum permitted cable length between any two devices on the P3 link before a
signal amplifier is required is 100 m (328 ft.) if good quality Ethernet cable is used for the link. A 1 GB
Ethernet switch on the P3 link is an ideal signal amplifier. If the P3 link will exceed the 100 m cable length
limit at any point in the installation, insert an Ethernet switch to boost the signal. If necessary, more switches
can be added each time the link reaches the 100 m limit.
Figure 19 shows the 1 GB Ethernet switch inserted between two panels on the P3 link as an example only:
the switch can be inserted in any position on the link where the cable length between any two devices would
exceed 100 m.
Important! More expensive, sophisticated switches tend to carry out additional processing that can cause
latency. You should therefore choose a relatively cheap unmanaged 1GB Ethernet switch.
