Appendix: Technical data
It may be necessary to also observe additional country-specific
regulations.
The local power supply must be constructed according to NEC. To improve
safety, the coffee machine should be fitted with an FI 30 mA earth leakage
current circuit breaker complying with EN 61008. Near the machine or about
12 inch (30 cm) below the counter top, there should be a shockproof socket
as a single-phase connection installed locally on the rear or side wall of
the counter substructure, or a country-specific single-phase socket. If the
mains connection lead for this coffee machine is damaged, then it must be
replaced by our customer service personnel or a similarly qualified person.
If the coffee machine is permanently connected to the mains, then an
all-pole disconnecting separator (mains switch) according to EN 60947 with
a minimum ⅛ inch (3 mm) contact gap must be installed. A separator switch
is recommended for a flexible connection. The mains cable must not come
into contact with hot surfaces. The mains switch and plug top are part of the
customer‘s on-site installation. The machine may not be fitted with a fixed
permanent mains connection if installed on a transporting trolley (a mobile
station).
In order to avoid possible faults from arising on our shielded data lines
due to potential equalization currents between the devices, an additional
potential equalization unit should be planned for devices connected to the
vending system. (See EN 60309)
