This permits the emergency operation of a drive system in the event of a power failure. Depending on the type, the drive is supplied with power from either one or two 9-volt batteries.
As a result of the extremely reduced capacity of the sources of power, the drive movement is restricted to a single emergency operation. In particular, please note that in many cases it is not possible to carry out a drive movement under load.
The batteries can have a transportation lock. In this case they must be connected before initial operation.
Extra-tough cable with an ethylene propylene rubber covering. This especially flexible, rubber-like plastic material is very good at preventing damage to the cable, including in cases of severe mechanical stress. For this reason, when used in situations in which safety is especially important, e.g. for patient care and hospital beds, EPR cables are specified as standard.
