DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

oDisconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires.

oPlace a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position.

oWait 15 minutes to allow the residual energy of the DC bus capacitors to discharge.

oMeasure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42.4 Vdc.

oDo not assume that the DC bus is voltage-free when the DC bus LED is off.

oBlock the motor shaft to prevent rotation prior to performing any type of work on the drive system.

oDo not create a short-circuit across the DC bus terminals or the DC bus capacitors.

oReplace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit.

oUse only the specified voltage when operating this equipment and any associated products.

Failure to follow these instructions will result in death or serious injury.

1

2

Remove the plug (2).

3

Partially unscrew the drain screw (3).

4

Suck out the used oil.

5

Inject new oil until the oil level reaches the middle of the groove (4).

6

Tighten the drain screw (3) to a torque level of 6 Nm (53 Nm).

7

Screw the plug (2) back in and tighten to a torque of 5 Nm (44 lbf-in).

8

Tighten the breather (1).

9

Verify the oil level of axis 2 again after a few rotations of the gearbox.
