5.6.2 Notes on electric installation
Important notes
– The electric installation must be carried out according to the wiring dia-
gram in chapter 5.6.1, the notes on electric installation as well as the
applicable local regulations. All information given in the wiring diagram
must be followed and observed.
– All cables must be lead into the unit via the cable openings equipped with
cable glands (e.g. option “CGcable gland”). The cable for the heating
voltage supply must be lead into the unit from the bottom via the cable
opening equipped with the clamp strap. Fix the cable with the clamp
strap.
– Make sure the cables do not scrub on any components.
– Maximum cable length and required cross section per wire must be
observed.
– The supply voltages must match the respective voltages (heating and
control voltage) stated in the wiring diagram.
Heating voltage supply
CAUTION!
Before connecting, ensure that the mains voltage corresponds with the
heating voltage for the unit (see type plate).
The Nordmann ES4 is to be connected to the mains supply in accordance
with the wiring diagram, via a service switch “Q2” (disconnecting device
with a minimum contact opening of 3 mm is an essential requirement) and
an fuse group “F2” (essential requirement, fuses are to be as detailed in
the following table). The supply wiring is to be fed into the unit via a tension
relieving device (cable gland) and connected to the terminals of the main
contactor “K1”.
