7.1.1 Connecting earth to receiver housing
To ensure the receiver against electrical interference the housing shall be connected to ground.
If a proper connection is not achieved by the fastening screws an additional earth cable shall be
connected to one of the fastening screws of the receiver. Recommended wire size 2,5 mm

.
For vehicles, ground refers to vehicle body.
Do not install the receiver on a vehicle/machine with positive grounding.
If the receiver is installed on an industrial truck the receiver must be mounted isolated
from the frame. In the antenna cabling a DC block must be used.
Åkerströms can provide one suitable DC block 944498-000.
The insulation resistance between the receiver and the frame shall be at least 1000 Ω
multiplied by the nominal voltage of the truck system according to EN 1175-1 + A1,
Safety of industrial trucks - Electrical requirements - Part 1: General requirements for
battery powered trucks.
7.1.2 Connecting power supply
The power supply is nominal 12/24 V DC, range 10 – 32 V DC. The input power supply wiring
must be sufciently fused, and if necessary it must be possible to disconnect manually from the
DC mains supply.

!
Both RCSS supply lines must be connected for correct functionality of the receiver.
7.1.2.1 Receiver and analogue interface supply
The maximum current consumption is 0,35 A excluding analogue interface.
The fuse for the input power supply shall be max 10AT, and of slow blow characteristic and
high breaking capacity.
If a switch is used for selecting Remote/Manual control the receiver and analogue inter-
face supply (VDD) shall not be connected to the switch together with the supply for other
outputs (VDD_1 - VDD_8).
