0478-0015-051 Safety information2 IntroductionThis braking resistor has been especially designed to be mounted withinthe heatsink of the Unidrive M600 / M70X, F300, H300, E200 & E300size 3. The design of the resistor is such that no thermal protectioncircuit is required, as the device will fail safely under fault conditions. Thein built software overload protection is set-up at default to protect thebraking resistor.Contents of the box (1220-2752-01)The following items are supplied in the box:• 1 x 75  Brake resistor assembly• 2 x Cable crimps• 1 x Installation sheet3 InstallationStep 1: Removing the terminal coversFigure 1-1 Removing the AC and DC terminal covers• To remove the terminal covers, undo the screw and remove thecovers in direction shown above (Figure 1-1).• The AC terminal cover (1) must be removed prior to the DC terminalcover (2).• When replacing the terminal covers the screw should be tightened toa maximum torque of 1 N m (9 lb in).Step 2: Removing the internal EMC filterFigure 1-2 Removing the internal EMC filterThe internal EMC filter needs to be removed to establish brake resistorelectrical connections. To remove the internal EMC filter:• Loosen / remove the screw and nut as shown (1) and (2)• Lift away from securing points and then rotate away from the drive (3).Ensure the screw and nut are replaced and re-tightened with amaximum torque of 2 N m (18 lb in).Step 3: Preparing for installationFigure 1-3 Removing the brake resistor bungRemove the brake resistor bung from the hole in the chassis as shownabove. The cap at the closed end of the bung will need to be removed,see Figure 1-4.Figure 1-4 Removing the bung cap (end with lug on)Remove the end of the bung with the lug on by piercing with a pair oflong nose pliers and pulling out in the direction shown above to leave ahollow bung so that the cable can be routed through.Unidrive M600-M70X, F300, H300, E200 & E300Size 3 Braking Resistor Installation SheetStored chargeThe drive contains capacitors that remain charged to apotentially lethal voltage after the AC supply has beendisconnected. If the drive has been energized, the AC supplymust be isolated at least ten minutes before work maycontinue. Refer to section 3.1 Safety information in the UserGuide.The heatsink and heatsink mounted braking resistor canreach temperatures in excess of 70 °C (158 °F). Humancontact with the heatsink and heatsink braking resistor shouldbe restricted.To avoid the risk of fire when the drive is surface mountedwith the braking resistor installed, the backplate should bemade from a non-flammable material.WARNINGWARNINGWARNING
