The Powered Cradle Option
7.11.5 The Powered Cradle Option
The powered cradle option is designed to allow the 7535 to be powered by a vehicle battery. The battery installed in the 7535 is also recharged by the vehicle battery.
This option accepts DC power sources over the range 12V to 90V.
The 7535 picker cradle can be ordered with the powered cradle option installed, or it can be retrofitted later. If you are retrofitting a power cradle option, the supplied kit includes detailed installation instructions.
The 7535 charging LED (see Section 3.6.1.1 on page 46) indicates that external power is available, and it also indicates the charging status of the internal battery.
Warning: Applying a voltage above 90VDC or reversing polarity may result in permanent damage to cradle power option and will void the product warranty.
7.11.5.1
Wiring Vehicle Power To The Cradle
A 2 meter extension power cable (PN 13985) is supplied with your power cradle.
This cable should be wired to a filtered, fused (maximum 6A) accessory supply on the vehicle. The power cradle draws no more than 3.5A (less if the accessory supply is greater than 12V). Any additional wiring, connectors or disconnects used should be rated for at least 6A.
The red lead of the power cable attaches to the positive vehicle supply. The black lead connects to the negative supply – this should be connected to a proper terminal block and not to the vehicle body. The power cradle 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 preferable to wire the power cradle after the key switch – that is, it cannot be turned on without the key on. However, if the operator switches the key off repeatedly during a shift, it may make more sense to wire the cradle before the switch.
If an unfused power source must be used, a fuse assembly (PN 19440) must be added to the extension power cable (the fuse and instructions are supplied with the cable). Use only a 5A slow blow UL approved fuse in the fuse assembly.
