MOUNTING

The instrument is intended for panel mounting.
EARTH TERMINAL (for grounding interferences)
If outside interference voltage act on the instrument, functional troubles may be caused (concerns also high-
frequency interferences). For grounding interferences and ensuring the electromagnetic immunity, an
earth must be connected: Terminals 7 and A must be connected to earth potential by means of a short
cable (approx. 20 cm. e.g. to switch cabinet ground)! Keep this cable separate from mains cables.

ELECTRICAL CONNECTIONS

Keep mains cables separate from signal and measuring cables. We recommend twisted and
screened measuring cables (screen connected to earth). Protective earth must be connected!
Connected final elements must be equipped with RC protective circuits to contactor manufacturer
specification, this avoids voltage peaks which can cause trouble to the indicator.
The instruments must be protected by an individual or common fuse for a max. power consuption of 10 VA
per unit ( standard fuse ratings, min. 1A) !
Signal and measurement circuits may carry max. 50 V r,m,s, against ground,
a
mains circuits may carry max. 250V r.m.s. between terminals.
