Note: Other ranges and cable lengths are available on request.
	Overvoltage protection:
LPN-OVP-E	We strongly recommend that an overvoltage protection device is used with the JUMO 4392 / 4391 if long runs of cable are involved in the installation; to protect against potential Lightning strike or earth potential rises.
	Accessories:
Terminal Housing	Terminal Housing with pressure equilibration (Pt No 00061206).
Cable Holder	Cable Holder (Pt No 00061389).
