AC power

Warning! Read "Safety Information" on page 3 before connecting the Stagebar 54 to AC power.
Lock out power to the entire distribution system before carrying out installation work.
Warning! Replace fuses with ones of the same type and rating only.
Important! Do not supply the fixture with power via an external dimming system, or you may cause
damage the fixture that is not covered by the product warranty.
The Stagebar 54 features an auto-sensing switch-mode power supply that automatically adapts to
100 - 240 V nominal AC power at 50 or 60 Hz. Only connect the fixture to AC power within this voltage
range.
The fixture is protected by a 4 amp slow-blow primary fuse located in a fuseholder on the rear panel (see
Figure 1 on page 6). The power output circuit is protected by a 15 amp slow-blow fuse located inside the
fixture. See "Fuse replacement" on page 20 for details of changing fuses.

Power connection

Warning! For protection from electric shock, the fixture must be grounded (earthed). Power
distribution circuits must be fitted with a fuse or circuit breaker and ground-fault (earth-fault)
protection.
Power is supplied to the fixture via a blue Neutrik PowerCon inlet that accepts a blue PowerCon NAC3FCA
cable connector. Power can be relayed to another device via the light-grey PowerCon outlet that accepts a
light-grey PowerCon NAC3FCB cable connector. Note that blue input and light-grey output connectors have
different designs: one type cannot be connected to the other.
You may need to fit the power cable with a power plug that is suitable for your AC power outlets. If so, install
a grounding-type (earthed) plug that is rated 20 A minimum. Follow the plug manufacturer's instructions.
Table 1 shows some possible pin identification schemes; if pins are not clearly identified, or if you have any
doubts about proper installation, consult a qualified electrician.
There is no separate power on/off switch: power is applied to the fixture as soon as it is connected to power.

Relaying power to other devices

Important! To avoid blowing the power output fuse, the total current draw of all devices connected to
one fixture's power outlet must not exceed 15 amps peak, 11 amps constant.
Fixtures can be linked in a chain, power outlet to power inlet, so that they all draw power via the first fixture,
but certain points must be respected:
• Either the supplied power cable or a three-conductor cable rated SJT, 20 A minimum (12 AWG or
2
2.5 mm ) must be used to connect the first fixture to AC power.
• Either the supplied power cable or a cable rated SJT, 15 A minimum (AWG 14 or 1.5 mm
to connect the subsequent fixtures in the chain to the first fixture.
