Protection
The KEY input is protected against reverse polarity with a diode and it has got
approximately a 2.2 nF capacitance to -B for ESD protection and other filtering
elements. This capacitance may give a high current spike at the KEY input
depending on the external circuit.
Fuse FU1 (see functional drawings, paragraph 3.2), should be sized according to
the number of motor controllers connected to it (10 A fuse is recommended) and
the current absorption of the KEY input (input power below 15 W).
 The key switch connected to the KEY input must handle the short inrush
current spike to the ESD protection capacitors. The current peak depends
on the external circuit and wires.
 Cables from the battery to the KEY input should be as short as possible

4.4.2 Digital inputs
Digital inputs are meant to work in the voltage range from -B to +B. Related
command devices (microswitches) must be connected to +B (typically to the key
voltage) or to -B, depending on the input configuration (refer to pin description in
the paragraph 4.4.2). Pull-down or pull-up resistors are built-in.
Functional devices (like FW, BW, LOWER, etc.) are normally open, so that each
associated function becomes active when the microswitch closes. Safety-related
devices (by default only SR/HB) must be normally closed, so that each
associated function becomes active when the microswitch opens.
Nominal voltage figures for digital inputs in standard Zapi configuration are listed
below. Custom hardware may feature different voltage values.
