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 1.5 mm
2
(14
AWG) minimum, three-conductor SJT (or better) power cable rated 8 amp minimum with an IEC female
cable connector.
Power plug
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 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.
