INSTALLATION INSTRUCTION REMOTUS 96XX 92 3161-000 Ver. C0 Page 1(3)

The following guide shall be used when installing Åkerströms Remotus CU9600 system, in
order to obtain a completely reliable operation. The installation shall be done by a competent
person.

1. MOUNTING

The permanent installation of the building must submit fuses which protect the equipment and
wiring from over-current and short-circuit. In detail the regular power supply of the equipment
and all relay-contacts must be fused.
All that fuses are used as separation devices. They must be easily accessible, must submit a
contact-gap of at least 3,0 mm and has to be placed in the line pole (L).

After the installation of the equipment, the installed cables must be bound together (e.g. by
using a cable binder) very close to the terminal blocks.

1.1 AERIAL PLACEMENT

The antenna for the receiver shall be placed as open as possible. Further information can be
found in drawing 90 8473-000.

1.2 CONNECTION CABLE

Connection cable for power supply and main contactor (MC):

The cable shall have a CONCENTRIC SHIELD e.g. ÖLFLEX or similar and with a cable
area of 0,75-1mm². We recommend grounding the cable the same way as the cable for
Profibus (according to the figure below).
Voltage supply: 24 VDC (11-35 VDC)
Power consumption: Max 9W

Connection cable for Profibus:

We recommend the following cable type (Type A).
Type A is in particular suitable for high data rate (>500kbit/s).
Technical specification:
Impedance: 35 up to 165 Ohm at frequencies from 3 to 20MHz
Cable capacitance: <30pF by each meter
Cable area: >0,34mm², similar to AWG 22
Cable type: Twisted pair. 1x2 or 2x2 or 2x4 wires
Resistance: <110 Ohm by each km.
Signal attenuation: Max. 9dB over entire length
Shield: Double shield i.e. shield cover and shield foil
Max Bus length: 200 m at 1500 kbit/s, up to 1,2 km at 93,75 kbit/s

Place the cable for PROFIBUS separated from the cable for power supply.

It is recommended to connect the shield on both sides low inductively with the protective
ground. Preferably the connection between shield and protective ground is made via the metal
cases. It should be noticed that this is not the optimal solution. In such a case it is better to
bare the cable shield at an appropriate point and to ground with a cable as short as possible to
the metallic structure of the cabinet. This could be achieved with a ground screw in front of
the CU96XX receiver.
If the machine parts NOT have the same ground potential, a equalization cable with great area
(e.g. 16mm²) most be connected between the parts and to the central protective ground.

Any modification to the equipment not expressively authorized by the party responsible for
compliance could void the user's authority to operate the equipment.

This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

FCC note:
The equipment user is required by the radio service rules to obtain a licence before operating the
equipment.

1.3 CONNECTION EXAMPLE FOR THE MAIN CONTACTOR
The maximum switching capacity of the relay contacts is 8A/250VAC at cosϕ=1.

Current loops that contains the relay contacts shall have a protection fuse rated 6 A.

Receiver

PROFIBUS DP

The receiver functions as a Profibus DP slave and have the identity 0x0765. This is fixed and
corresponds to the unit function as a Profibus DP slave.

• 16 byte consistent data in. The last byte is a checksum total for the 15 preceding bytes.

• 16 byte consistent data out.

On the Profibus board there are two rotary switches on which you can adjust the Profibus DB
slave address. The default address is 55.
A diskette with TYPE- and GSD-files are included with each delivery.
