AC power and data connection to PSU

Warning! Read 'Safety information' on page 5 before installing the fixtures and PSU.
Electrical installation must be carried out by qualified professionals only. Lock out power to
the entire installation before working on cables and connections.
For protection from dangerous electric shock, the PSU must be grounded (earthed). The
AC power distribution system must be fitted with current overload and ground-fault (earth-
fault) circuit breakers as well as a means to isolate fixtures from power and lock out power
during service.
In the RUSH® CS Series system, AC power and DMX control data are connected to the RUSH® CS
Power Supply Unit (PSU). The PSU then sends low voltage DC power and DMX data to one or more
fixtures using a custom 6-pole connector.
Important! Do not connect or disconnect a live power and data cable. Shut down power to the installation
before connecting or disconnecting cables.
The RUSH® CS PSU accepts AC power at 100 - 240 V nominal, 50 or 60 Hz. Do not connect to power at
any other voltage or frequency.
There is no power on/off switch. Power is applied to the PSU and fixtures as soon as they are connected
to power. Provide a means to disconnect or shut down power to fixtures that is easily accessible and is
located close to the fixtures.
Do not use an external dimming system to supply power to the system, as this may cause damage to the
system that is not covered by the product warranty.

Power requirements

The RUSH® CS PSU must be supplied with AC mains power at 100 - 240 V nominal, 50/60 Hz using
either a grounded single-phase (live, neutral, ground/earth) distribution system or one phase of a
grounded three-phase (3 live phases, neutral, ground/earth) distribution system.

Connecting fixtures

All fixtures are fitted with captive input and output cables, carrying data and power using a custom 6-pole
connector. Fixtures can be connected end to end using the captive cables, or if the fixtures need to be
separated they can also be connected using the 1 m (3.2 ft.), 5 m (16 ft.) or 10 m (32 ft.) extension cables
listed under 'Accessories' on page 23.
The blue connector is the input connector and the black connector is the output to the next fixture in the
chain.
Maximum total length of fixtures
The PSU can power up to 10 meters of RUSH® CS fixtures. For example, eight 1200 mm fixtures, eleven
900 mm fixtures, seventeen 600 mm fixtures or thirty-two 300 mm fixtures.
If you connect too many fixtures, the PSU will shut down to protect itself. When the extra load is removed,
the PSU will resume normal operation.
Maximum total length of cable
If you connect additional extension cables between the PSU and the first fixture, or between fixtures, a
maximum length of cable applies due to voltage drop in the cable. If the cable is too long, the fixtures
furthest from the power supply will lose intensity. This will be particularly visible on the green and blue
LEDs, so colors will tend to shift towards red.
The maximum recommended length of one system is 50 m (164 ft.) including both cable and fixtures.
