VAR8-ACU and Variants - Installation Guide
1.1 Installation Requirements
• The VAR8-ACU unit.
• A 19-inch standard rack and wiring for power supply, signal monitoring, and RS232 and RS485 cabling
as appropriate.
• A small flat-bladed screwdriver.
• Large pozidrive screwdriver.
• Cable termination tools - cutters/strippers etc. to suit cable type.
1.1.1 Cabling Requirements
The following cabling is recommended within the equipment rack. For pinout refer to Figure 1 (page 5), and
for cabling connector refer to Section “2 Connections” (page 11).
1. DC power supply cabling:
Standard cable rated for 3 A.
Recommended type: BELDEN 8205LSHF.
2. Audio input:
Twisted pairs, individually screened.
Recommended type: BELDEN 8451 LSHF.
The rack and field cabling should be as described in the diagram shown in Figure 3.
3. Audio and data network cabling:
Twisted pairs with overall foil screen.
Recommended type: FS cables 2407 POFYH.
The Upstream side of the network connection is isolated RS485. The rack and field cabling should be as
described in the diagram shown in Figure 2.
4. Other cabling:
Overall screened.
Recommended type: BELDEN LS0H.
The rack and field cabling should be as described in the diagram shown in Figure 3.
The use of screened cables where specified is necessary for EMC compliance. Also for EMC
compliance, rack and field cabling should be according to the specified diagram.

5 Safety and
Precautions
5.5 Lithium Battery
Danger of explosion if battery is
incorrectly replaced. Replace only
with the same or equivalent type.
Dispose of battery carefully to avoid
environmental damage. Do not
dispose of battery in a fire.
5.1 Environmental
The temperature and humidity ranges shown in
the specifications for this product must not be
exceeded.
This equipment must not be installed in an area
that is subject to a corrosive atmosphere,
excessive moisture or may allow water or other
liquids to come into contact with the unit or its
external connections.
5.6 Unpacking and Handling
The equipment should be unpacked and
inspected immediately on receipt. If damage has
occurred please advise your carrier or supplier.
In the close proximity of some radio frequency
transmitters, the signal to noise ratio of this
product may be reduced. If this occurs, re-location
of the equipment or the signal cables is
recommended.
It is advisable to retain the original equipment
packing in the event that the equipment ever
needs returning for service.
Ensure that the name and address of the
Authorised Distributor from whom you purchased
the unit is recorded on the "Service and Warranty"
page of this manual for future reference.
5.2 ESD
This product contains static-sensitive devices.
Observe ESD precautions when working on the
equipment with the cover removed. 5.6.1 Packing for Repair
All electronics assemblies must be
properly packed in ESD protective
packing for transport, to prevent
physical and ESD damage. Use of
non-ESD protective packing for return
for repair or service will automatically
invalidate the warranty.
5.3 EMC
EMC compliance is dependent on this unit being
wired in accordance with these installation
instructions.
5.4 Electrical Safety
The filler material used for packing for
return for repair must be antistatic or
static dissipative, as this may come
into contact with exposed connectors,
wiring, or PCB assemblies. The use
of non-conductive filler material may
cause damage to the electronic
assemblies reducing their operational
life, or even destroying them, and it
will automatically invalidate the
warranty.
Always replace blown fuses with the
correct type and rating.
Ensure adequately rated cables are
used for power supply.
