Chapter 4: 8580/8590 Installation
Cable Cover (Splash Guard)
8580/8590 Vehicle-Mount Computer User Manual 49
To safely wire power to the 8580/8590, review these guidelines and follow the instructions
that apply to your needs:
• When connecting the cable (PN 13985-301) to the screen blanking cable (PN 1616303-
001), the wire pair on the 13985-301 labelled “screen blanking” connect to the screen
blanking control device, which must provide an isolated relay closure across the pair.
• When connecting the cable (PN 13985-301) to the ignition cable (PN 1616302-001), the
wire pair labelled “screen blanking” on the 13985-301 has a different function; the red
wire must connect to a DC+ voltage source switched on by the ignition, while the black
wire may connect to DC- or be taped off.
• Note that only the ignition function is supported by the UPS (PN PS1110/PS1120), not
screen blanking. If both screen blanking and ignition are to be used on the same
8580/8590, a separate cable must be provided to connect the screen blanking relay
closure to COM2.
Contact Psion for details about the Pre-regulator, model number PS1320 and the Interrupted
Power Supply (UPS), model number PS1110 and PS1120 (freezer unit).
