NSTALLATION
In this chapter we describe the electrical installation of the appliance. About the mechan-
ical mounting you have learned in
Z Mounting – from page 31.
The steps for installation are:
1 find out and check the required specifications of the power supply. Make sure the
mains meets the requirements.
2 find out what electrical wiring is required and supply the respective cables.
3 find out the characteristics of the connections and configure the cables respectively.
4 follow the EMC guidelines when routing the cables.
5 Is the fastening to be carried out according to UL 508C? If “yes“, use a suitable torque
wrench (see
Z Fastening according to UL – on page 60).
6.1 General hazard information
The BUM64S/A/F appliances are defined as working funds of protection class I in respect
of HD366 S1 chapter 3.2, see also EN 50178/VDE 0160 sect. 5.2.9.
Working funds of class I are characterized by the fact, that the protection against danger-
ous body currents not only comes from the basic insulation. Furthermore they are
equipped with additional safety precautions. This additional protection consists of the
housing and other parts being supplied with a protective earth connection. So in case the
basic insulation fails there is no risk of dangerous voltages. The insulation of the appli-
ances is carried out across the total component at least in the basic insulation class ac-
cording to EN 50178/VDE 0160, sect. 5.2.9.1. This applies to the insulation between
current circuits and the environment.
The control connections of the appliance are secure isolated from the mains network.
They are laid out for use of PELV-/SELV-circuits.
When determining the air- and creepage distances the following criteria have been con-
sidered:
m Soiling grade 2 acc. to EN 50178/VDE 0160, sect. 5.2.15.2, table 2, line 3: Normally
only non-conducting pollutants are produced. When the units are out of service, brief
conductivity can occur due to condensation.
m Overvoltage category III according to IEC 664-1, table 1 for the air clearances of mains
circuits to their environment according to EN 50178/VDE 0160, sect. 5.2.16.1.
