The unit is housed in either a plastic or explosion proof housing upon request. A safety start circuit is provided which prevents emergency operation until the mains is connected and disconnected. This emergency control gear can also be supplied in a remote box format for easy installation.

The emergency control gear requires a 12V battery of either Ni-Cad, Lead-Acid or 11.1V Li-ion – dependent on request. A visible red pilot light indicates when the batteries are being charged.
