Danger of electric shock!
Dangerous electric voltage!
All work relating to the electrical installation
may only be carried out by designated spe-
cialist personnel (electrician or qualified per-
son with equivalent training).
The customer is responsible for monitoring
the qualifications of the specialist personnel.
General installation rules
•
All local rules concerning the imple-
mentation of electrical installations
must be obeyed
•
Electric connector cables to be laid pro-
fessionally
•
Install the electrical connections accor-
ding to the wiring diagram
•
With units of a nominal power output
> 33 kW electrical connection to a per-
manent line is mandatory (according to
VDE 0700 Part 98, IEC 60335-2-98)
Potential component damage due to elec-
trostatic discharge!
To protect the sensitive electronic compo-
nents, measures to prevent damage due to
electrostatic discharge must be taken before
the start of the installation work.
7.1 Electrical installation
approach
Do not connect the steam humidifier to the
live power supply before all installation work
has been completed.
»
Provide fuses with a contact gap of
at least .12 inch (3mm) per pole.
»
Install a separate main connection
for each steam cylinder including
main circuit breaker, main switch etc.
»
Make main connection according to
the table below.
Main connections, current draw and
fusing
The table on the next page shows the
respective values relevant for the various
models of the FLE steam humidifier series.
HygroMatik recommends the use of slow
blowing up to middle time-lag main fuses
(only applies to the a.m. mains supply volt-
age).
Steam humidifier installations should encor-
porate an individual resiliant current circuit
breaker (Type A-RCD).
7.2 Cable connections

dimensioning of the cable connections pro-
vided by the various StandardLine housing
