Removing the Covers
Disconnect the Betapack at the supply.
The mains supply connections and the channel output
terminals (Betapack 2 hardwired version only) are
under the top cover.
Remove the four screws (‘A’ in Diagram 6) from the
end plates to remove the cover.
The DMX links and the triacs are under the bottom
cover. Remove four screws (‘B’ in Diagram 6) from the
end plates to remove the cover.
Connecting the Mains
A separate isolator and secure mains earth
are required.
Phase to Neutral voltage must not exceed 255v.
Betapack 2s are supplied wired for single phase
operation. Cut outs are provided on the ends and rear
for PG21 glands; one is supplied.
Single Phase
Betapack 2s are supplied from the factory with two
busbars wired for single phase as in Diagram 2.
If the busbar for linking Live 1 to Live 2 to Live 3 is not
available, use 10mm
2
cable instead.
Three Phase ‘Star’
Remove the single phase busbar (if fitted) from across
the three phase input terminals Live 1,
Live 2 & Live 3. Ensure that the neutral busbar is in
place as shown in diagram 3 opposite.
Wire the supply to Live 1, Live 2, Live 3 and Neutral
using at least 2.5 mm
2
cable.
Three Phase ‘Delta’
Using suitable cable (4 to 6mm2) connect the supply
terminals together as shown in Diagram 4 opposite.
Wire the supply to Live 1, Live 2 and Live 3 using at
least 4.0 mm
2
cable.
Mains Supply Wiring
Always ensure that the
lockwashers
supplied are
used. Use an M5 ring tag securely crimped to the
mains supply wire if possible.
Otherwise ensure that the mains supply wires are
connected as shown in Diagram 7 and that the screws
are securely tightened.
Ventilation
When one or more Betapack 2s and/or Betapack 2
Plusses are mounted in an enclosed rack, a fan
MUST be fitted to ensure that adequate cool air is
circulated.
Up to three Betapack 2s / Betapack 2 Pluses may be
stacked in free air.
Mounting
In a 19" Rack
The Betapack 2 is supplied with side brackets fitted
for rack mounting.
On a wall
Undo the four screws ‘X’ to remove the brackets,
replace the screws in the holes for future use.
Stand the Betapack 2 on one end. Remove the two
screws ‘Y’ (see Diagram 6), fit the brackets as shown
and replace screws ‘Y’. Fit the other bracket on the
other end.
The wall drilling positions are shown in Diagram 8.
WARNING Completely fit one bracket at a time.
Removal of all four screws ‘Y’ at the same time can
allow the heatsink assembly to fall out!
Allow a minimum vertical spacing of 130mm between
packs and between packs and other equipment.
A spacing of 180mm is recommended for ease of
wiring and servicing.
For Portable Use
An ‘Easicarry’ Option Kit consisting of a handle and
four feet is available (Stock No: 00-540-00). Contact
your dealer for further details.
To fit, remove the brackets. Fit the handle using the
screws supplied and holes ‘Z’. Fit the four feet to the
other end using the holes ‘X’ and ‘Y’. See Diagram 6.
DMX Options (where fitted)
Remove the bottom cover to access these links as
described above.
DMX Control Law
As supplied the Betapack 2 DMX output provides a
linear law control. If a ‘S’ law is required
(eg when the Betapack 2 is part of a system which
has mixed analogue and DMX control), add a short
wire link between ‘LIN’ and ‘0v’ on the DMX Printed
Circuit. (See Diagram 5).
DMX Termination
Each Betapack 2 has a built in DMX termination.
It is connected by adding a short wire link between
‘EOL’ and ‘DMX-’ on the DMX Printed Circuit.
(See Diagram 5).
Connection ‘CHS’ referes to chassis and is unused.
Permanent Installation
Where Betapack 2s are permanently installed it is
possible to connect the DMX control cabling to the
dimmer internally. The terminals marked ‘DMX+’,
‘DMX -’ and ‘OV’ should be used (see Diagram 5).
