6.5.2 Non-Vehicle Installations
Using AC power, the 8515 Vehicle-Mount Computer can be mounted at fixed locations ad-
jacent to cross-dock doors, manufacturing stations, or in offices. The 110/220V Psion Tek-
logix AC adaptor Model PS1400 should be used to power the computer from an AC source.
6.5.3 Wiring Vehicle Power To The 8515
A 1.8 meter (6 ft.) extension power cable (P/N 13985-302 or P/N 13985-301 with screen-
blanking sensor) is supplied with your 8515 (see
Figure 6.12 on page 139 ). This cable
should be wired to a filtered, fused (maximum 6A) accessory supply on the vehicle. The
8515 draws no more than 6A (less if the accessory supply is greater than 12V). Any addi-
tional wiring (minimum 18 gauge), connectors or disconnects used should be rated for at
least 90 VDC, 10A.
The red lead of the power cable attaches to the positive vehicle supply. The black lead con-
nects to the negative supply—this should be connected to a proper terminal block and not to
the vehicle body. The 8515 is fully isolated and can be used with both negative and positive
chassis vehicles.
You may have the option of connecting power before or after the ‘key’ switch. It is prefera-
ble to wire the 8515 after the key switch—that is, the 8515 cannot be switched on without
turning the vehicle key on.
If an unfused power source must be used, a fuse assembly (P/N 19440-300) must be added
to the extension power cable (the fuse and instructions are supplied with the cable). Use only
a 6A slow blow UL approved fuse in the fuse assembly. The fuse assembly must be located
as close as practical to the DC supply, and shall connect to the positive side of the
DC supply.
6.5.3.1 Installing The Power Pre-regulator (PS1300)
The power pre-regulator should be used on all vehicles that run off voltages from 10V to
30VDC. This helps to eliminate power irregularities that may affect the computer’s operat-
ing system.
Note: Make sure the cables run inside the roll cage of the vehicle.
Warning: The 8515 accepts DC power sources between 10V and 30VDC nominal.
Applying a voltage above 30VDC or reversing polarity may result in perma-
nent damage to the 8515 and will void the product warranty.
