Power Requirements
The LSM 880 system comes with a mains power supply cord and plug, either CEE red
(3/N/PE 400/230 V/16A), or NEMA L 14-30P (2/N/Ground 120/240 V/30 A), and with the matching
mains socket outlet.
The mains socket outlet must be equipped with a fuse having minimum tripping characteristic C
according to IEC/EN 60898.

The LSM contains sensitive electronics. A few seconds of faulty power can damage parts of the
electronics. The system is therefore equipped with a surge guard, a device that protects the
electronics of the LSM from strong electrical power fluctuations like overvoltage, lightning or other
external influences.
The surge guard is located within the electrical connection box. It works once to protect the
system, then it has to be exchanged. Within warranty, service contracts or any other service visit
ZEISS service will check the functionality of the surge guard and provide a new device if necessary.
Nevertheless, in the rare case of a voltage surge on the power supply line (e.g. from indirect
lightning stroke), a momentary interruption of the acquisition system's functionality is possible. This
is no defect. Acquisition can be continued after starting the ZEN software again. Sample position is
maintained and no damage occurs to the system. A possible protective means to minimize the
probability of a temporary disruption is a transient voltage protector in your facility's power system.
