2.5 Electrical Safety
2.5.1 General
The main switch disconnects the machine from the mains supply at two poles.
Switch off the main switch if the instrument is to be inoperative for an extended period (e.g.
over night).
2.5.2 Protection against Restarting
In the event of a mains failure during operation or after switching-off with the main switch,
the hood can be opened. When the mains voltage is restored, for safety reasons, however,
the instrument will not start again.
2.5.3 Overload Protection (see 7 Troubleshooting Checklist)
In the event of overloading, the speed of the machine will be reduced.
If the drive motor overheats, the machine will switch off.
If the drive is obstructed, the machine will switch off.
2.5.4 Unbalance Detection (see 7 Troubleshooting Checklist)
In the event of an excessive unbalance, the machine will switch off.
2.5.5 Operation on a residual current circuit breaker
It is possible that the leakage current could approach limit values during operation. This can
result in tripping of residual current circuit breakers. Through the addition of all devices
onto the power circuit, these values can be reached very quickly.
Solution: Use a power circuit without residual current circuit breaker or increase the residual
current limit of the circuit breaker.
3 Installation
3.1 Unpacking
 Cut the packing belt; tear the tape off the cardboard box.
 Take the hood off the cardboard box.
 Check that the items supplied correspond to your order. Grinding jars of hardened steel
may exhibit surface indentations caused by the manufacturing process. These do not
influence the grinding or the grinding result and generally disappear after the first
grinding. When present, these surface indentations lie within the permissible
manufacturing tolerance ranges. Accordingly, complaints regarding such grinding jars
cannot be accepted.
3.2 Transport
Transport the mill on the transport pallet with a fork lift truck or a hand fork lift truck.
