Safety instructions

Use of the hand-operated winch
These instructions are intended for all who use the hand-operated winch delivered
with the drive when replacing the supply or inverter modules.
WARNING! Ignoring these instructions can cause physical injury or death, or
damage the to equipment.
• Before using the winch for the first time, spool out 2 meters (6 feet) of cable, then
rewind the cable onto the drum keeping enough tension on the cable to make
sure no slack is left on the drum.
• When lowering the module, keep in mind that any slack on the winch may cause
the module to suddenly drop for several centimetres.
• After using the winch, rewind the cable onto the drum keeping enough tension on
the cable to make sure no slack is left on the drum.
Work on the liquid cooling system
These instructions are intended for all who are responsible for installation and
maintenance work of the liquid cooling system of the drive.
WARNING! Ignoring the following instructions can cause physical injury or damage
to the equipment:
• Beware of hot liquid. Do not work on the liquid cooling system until the pressure is
lowered down by stopping the pumps. High-pressure warm coolant (6 bar, max.
50°C) is present in the internal cooling circuit when it is in operation.
• Before power switch-on, make sure that the internal cooling circuit is filled up with
coolant. Running the pump dry will damage it. Also the drive will not cool down.
• Units with a liquid cooling unit option (+C199, +C140, +C141): Do not open
the pump inlet or outlet valves before filling up the internal cooling circuit. The
pumps are prefilled with a water-glycol-inhibitor mixture to prevent corrosion and
the valves are closed at the factory.
• Avoid skin contact with coolant, especially antifreeze. Do not syphon them by
mouth. If such substance is swallowed or gets into the eyes, seek medical advice.
• Do not overtighten the outer union of the nuts of the liquid
hoses - leave 2 to 3 mm of thread visible. Overtightening will
break the hose.
• Drain the unit before storing in temperatures below 0°C.
Freezing of the liquid cooling system is not allowed. If the ambient temperature is
below +5°C, add antifreeze and corrosion inhibitors to the cooling liquid.
Operation at temperatures below zero is not permitted, not even with antifreeze.
