4.1 Installation notes
k The choice of the cable, the installation and the electrical connection
must conform to the requirements of VDE 0100 “Regulations on the In-
stallation of Power Circuits with nominal voltages below 1000V”, or the
appropriate local regulations.
k Work inside the instrument must only be carried out to the extent de-
scribed and, like the electrical connection, only by qualified personnel.
k If contact with live parts is possible while working on the instrument, it
must be isolated from the supply on both poles.
k The electromagnetic compatibility (EMC) conforms to the standards and
regulations listed under Technical Data.
v Chapter 7 “Technical data”
k Run the input, output and supply cables separately, and not parallel to
one another.
k All input and output cables without connection to the supply network
must be arranged as twisted and screened cables. Earth the screen on
the instrument side to the earth potential.
k Earth the instrument at the PE terminal to the protective conductor. This
cable should have the same cross-section as the supply cable. Earthing
cables should be run in a star layout to a common earthing point which is
connected to the protective conductor of the supply. Do not loop the
earthing cable, i.e. do not run it from one instrument to another.
k Do not connect any additional loads to the supply terminals of the instru-
ment.
k The instrument is not suitable for use in hazardous areas.
k Inductive loads close to the instrument, such as contactors or solenoid
valves, should have RC modules fitted for interference suppression.
k The supply to the instrument must be provided with additional fusing.
Depending on the supply voltage, the following fuse values apply:
20 — 30V AC/DC, 48 — 63Hz : fuse 2A slow
110 — 240V AC +10/-15%, 48 — 63Hz : fuse 1A slow
A type-G miniature cartridge fuse marked F1 is built into the instrument
itself:
20 — 30V AC/DC, 48 — 63Hz : fuse 1.6A slow
110 — 240V AC +10/-15%, 48 — 63Hz : fuse 0.63A slow
