For microwave combination ovens on a wheeled platform, the length of the mains power lead must
accommodate the degree of movement allowed to the appliance by the retaining device on the
wheeled platform. When moving the assembly (platform plus appliance), never place the mains
power lead under tension.
All electrical connections must be checked when the appliance is prepared for first-time use to ensure
cables are laid correctly and connections are made properly.
Equipment provided by customer and electrical installation regulations
The table below shows what equipment must be provided by the customer and what regulations must be
observed when connecting the appliance.
Equipment
Regulations
Fuse
Fuse protection and connection of the appliance must comply with local regulations
and national installation requirements.
Equipotential bonding
The appliance must be incorporated in an equipotential bonding system.
Equipotential bonding: electrical connection that ensures that the frames of elec-
trical equipment and any external conductive components are at an equal (or
practically equal) potential.
Residual-current device
(RCD)
The installation regulations require protection by a residual-current device (RCD).
Suitable residual-current devices meeting the relevant national regulations must be
used.
If the installation includes more than one appliance, one residual-current device
must be provided for each appliance.
Disconnection device
An easily accessible all-pole disconnection device with a minimum contact separa-
tion of 3 mm must be installed close to the appliance. The appliance must be
connected via this disconnection device.
The disconnection device is used to disconnect the appliance from the electrical
supply for cleaning, repair and installation work.
Fitted frequency-converter
The appliance is fitted with one frequency converter (FC) and an EMC mains input filter.
These devices may result in a leakage current of more than 3.5 mA per FC drive.
Use a suitable RCD for the rated voltage.
Properties of the residual-current device
The residual-current device (RCD) must have the following properties:
Filter for filtering out RF currents
“Time delayed" trip characteristic for RCD devices with trip threshold >30mA: prevents RCD being
tripped by charging currents of capacitors and parasitic capacitances when appliance is switched on.
“Leakage current protection, type SI” trip characteristic for RCD devices with trip threshold
30mA:
insensitive to nuisance tripping.
