Basic safety precautions

2.2.1

Product safety

The POLIM® and MWK/MWD type surge arresters have been constructed using state-of-the-
art technology and officially recognised safety-related rules. However, while they are in use,
danger to life and health of the user or third parties could arise, or damage of the surge
arresters and other property could occur.
The POLIM® and MWK/MWD type surge arresters are only to be used when they are in
X
technically sound condition, for the intended purpose, and with safety and the possible
dangers in mind while observing the operating instructions.
Keep the operating instructions intact and fully readable, and store them in such a way
X
that they are accessible to operating personnel at all times.
Decommission and replace overloaded or damaged surge arrester units.

Intended use

The POLIM® and MWK/MWD type surge arresters are intended for use in high-, medium- and
low-voltage applications.
Surge arresters protect the insulation of devices against overvoltages which are caused by
lightning or switching operations.
The manufacturer is not liable for resulting damages from further, unintended use. The
operator accepts all responsibility for using the POLIM® and MWK/MWD type surge
arresters outside of their intended application range as specified in this document or in the
respective data sheet.
