You have now completed the
installation of components, but do
not begin using the fixture until you
have carried out the safety tests
described in the next section.

Safety testing

Warning! The two tests described below must be carried out before the upgraded MAC 575 Krypton

Low-Noise can be considered safe. Do not operate the fixture until it has passed these tests.

Specialized test equipment is required for these two tests. Suit able test equipment, such as the Electrical
Safety Tester series from Instek (http://www.instek.com) for example, is available at the moment
(summer 2008) for around 600-700 US dollars.

Ground bond test (earth bond test)

105.Open the ballast side base top cover. Test the resistance between the ground (earth) conductor in
the power cable and each of the ground leads on the pan frame in turn. If resistance exceeds 0.75
ohms, clean and re-establish all connections and repeat the test until you measure less than 0.75
ohms between the ground conductor in the power cable and each of the two gro und leads. Do not
proceed to the next test until the fixture passes this test.

106.Reinstall the cover.

High-potential dielectric withstand test

Warning! Dangerous voltage. Follow all safety instructions printed in your appliance tester’s user manual

and on your appliance tester.

107.Ensure that the fixture’s power cable is not connected to power. Temporarily lin k the live (brown) and
neutral (blue) conductors in the fixture’s power cable together so that there is electrical continuity
between them.

108.Connect one terminal of a PAT (portable appliance tester) device to the combined live and neutral
conductors in the fixture’s power cable. Connect the other terminal of the PAT device to the ground
conductor in the fixture’s power cable.

109.Make sure that the fixture’s main on/off power switch is set to ON.

110.You are about to apply a very dangerous and potentially lethal voltage. Ensure that it is impossible
for exposed conductive components in or on the fixture to come into contact with persons, or any
conductive surface or substance that persons may touch, during this test.

1 11. Set the maximum current on your PAT device to 20 mA, then use the PAT device to apply 1500 VAC

for a maximum of 1 second to the conductors you have connected it to.

Figure 101

MAC 575 Krypton Low-Noise Upgrade Kit Installation Guide – Page 46 of 46

112.If a flashover or arcing occurs, disconnect the PAT device, check all points of the installation, then
repeat the test.

113.Separate the live and neutral conductors again before connecting the fixture to normal AC power.
