10 smartMAC user manual

To change voltage and frequency settings:

1. Disconnect the fixture from power and allow to cool for at least 30 minutes.

2. See Figure 2. Loosen the 4 Phillips screws in the display side cover on either side of the display panel

and lift the cover away from the fixture.

3. Locate the selector switches on the PCB behind the display.

4. Move the voltage switch to the setting closest to your local AC voltage. If your voltage is halfway between

2 settings, select the higher setting. For example, if your local voltage is 110 V, set the voltage selector to

120 V. if your local voltage is 220 V, set the voltage selector to 230 V.

5. Move the frequency switch to the setting that matches your local AC frequency: 50 or 60 Hz.

6. Reinstall the cover before reapplying power.

Power cable

The smartMAC must be connected to power using either the supplied power cable or a listed 1.0 mm

(18

AWG) minimum, three-conductor SJT (or better) power cable rated 8 amp minimum with an IEC female

cable connector. The supplied power cable has an angled IEC female power input connector on one end but

no power plug. It can either be hard-wired to a building’s installation circuits or fitted with a power plug that is

suitable for your AC mains power outlets.

Power plug

If you install a power plug, 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 some possible

pin identification schemes; if pins are not clearly identified, or if you have any doubts about proper

installation, consult a qualified electrician.

Applying power

Important! Do not supply the fixture with power from a dimmer system, as this may cause damage that is not

covered by the product guarantee.

Check that power cables are undamaged and rated for the current requirements of all connected devices.

Plug the fixture’s power cable into the fixture’s IEC socket and a grounded (earthed) source of AC power.
