AC power

Warning! Read “Safety Information” starting on page 3 before connecting the MAC 401 Dual™ to AC

mains power.

For protection from electric shock, the MAC 401 Dual™ must be grounded (earthed). The AC power

distribution circuit must be equipped with a fuse or circuit breaker and ground-fault (earth-fault)

protection.

The MAC 401 Dual™ does not have a power on/off switch. To shut down power urgently, disconnect

the fixture’s power input connector.

Important! Do not use an external dimming system to supply power to the MAC 401 Dual™, as this

may cause damage to the fixture that is not covered by the product warranty.

The MAC 401 Dual™ can be hard-wired to a building electrical installation if you want to install it

permanently. If you do this, provide a means of shutting down power near the fixture. Alternatively a power

cable (not supplied) with a power plug suitable for local power output sockets can be used to supply the

fixture with AC mains power.

Power voltage

Warning! Check that the voltage range specified on the fixture’s serial number label

matches the local AC mains power voltage before applying power to the fixture.

MAC 401 Dual™ fixtures are factory-configured to accept AC mains power at 100-240 V nominal, 50/60 Hz.

Do not apply AC mains power to the fixture at any other voltage than that specified on the fixture’s serial

number label.

Power cable and plugs

The fixture must be connected to AC power using three-conductor cable that is rated 20 A minimum (12

AWG or 2.5 mm

), with a diameter of 5 - 15 mm (0.2 - 0.6 in.). The cable jacket must be SJT type or better

and heat-resistant to 90° C (194° F) minimum. A power cable is not supplied with the product.

The MAC 401 Dual™ is supplied with a male Neutrik PowerCon NAC3FCA locking 3-pole input connector

that can be attached to the end of the power cable.

The power cable can either be permanently connected to a building’s electrical installation circuits (in this

case an external power switch must be installed close to the fixture) or fitted with a power plug that is

suitable for the local AC mains power outlets.

If you decide to install a power plug on the fixture’s power cable, install a grounding-type (earthed) plug that

is correctly rated for the current and power requirements of the fixture. Follow the plug manufacturer’s

instructions. Table 1 shows standard wire color-coding schemes and some possible pin identification

schemes; if pins are not clearly identified, or if you have any doubts about proper installation, consult a

qualified electrician.
