The
Dimming / Switching Datapaks
are capable of dimming or
switching resistive and inductive loads, and switching capacitive
loads. To dim capacitive loads, e.g. projectors with power factor
correction (PFC) capacitors, remove their PFC capacitors.
The
Switching Datapaks
are capable of switching resistive and
inductive loads, but they are not suitable for capacitive loads.
This makes the
Datapak range
suitable for running all types of low
voltage lamps, electric motors, neon lights, properly ballasted
fluorescent lamps etc. besides ordinary resistive tungsten lamps.
INSTALLATION AND SERVICE
must only be carried
out by suitably skilled and competent persons. The
Datapak must be connected in accordance with current
local and national wiring regulations. When not in use for a period of
time or before working on the lighting installation, replacing lamps or
loads, the Datapak should be isolated (disconnected) from the mains
supply. If the Datapak is not installed or operated according to this
instruction leaflet then the protection provided by the Datapak may be
impaired.
WARNING - THIS APPLIANCE MUST BE EARTHED
INSTALLATION AND VENTILATION
All Dimming and
Switching Packs generate a certain amount of heat, so it is essential
to leave a 25mm air gap around the Datapak. Rack cabinets should
be ventilated or open backed. Do not obstruct the cooling air inlets
on the back panel or outlets at the top right hand corner. The
Dimming/Switching models contain a fan. The mounting brackets
supplied space the Datapak suitably from a wall.
19” RACK MOUNTING
To rack mount your Datapak remove the
four M4 countersunk screws that hold each of the two wall mounting
brackets. Rotate and re-fix these to the front four nutserts provided
along each side of the Datapak.
A CONNECTION PANEL
for hardwiring the mains input/output
connections are located on the bottom panel.
To allow cable access to the mains input and outputs, remove the
appropriate knockout (20, 32mm) from the panel.
Knockouts removed, but not in use, must be covered up.
A further two blanking plugs (25, 32mm) are located on the right of
the top panel to allow the entry/exit of such cables.
The signal inputs are accessed by removing the 20mm blanking plug
from the bottom panel. Another blanking plug is located on the left
of the top panel to allow the entry/exit of such cables.
Signal cables following this route
must
be double insulated, mains
rated.
LEVER OPERATED TERMINAL BLOCKS
are used for all
input /output connections for speed and reliability.
Use a small bladed screwdriver or similar, to operate the lever.

2.5 mm

MAINS SUPPLY
Important:
For your Safety the Datapak must be Earthed, fed via a
Residual Current Circuit Breaker and Local Isolator fused for the max
IMUM current taken by the load. You might find a Pulsar Mains
Distribution Unit suitable.
Mains Voltage:
100 - /-10%, single or three phase, star or
delta. There is no voltage selector - the electronics automatically
adjusts to the incoming voltage.
Mains Frequency:
48-62Hz, the electronics automatically adjusts to
the frequency.
Power Consumption:
The Datapak itself uses very little power, so
the maximum power consumed (when all the lights are on full) = the
total wattage of lamps connected. The maximum load per channel
is 5, 10 or 20 Amps - see Front Panel.
MAINS CONNECTIONS
Live, Neutral and Earth Inputs:
As supplied, the, short brass bars are set for 3 phase star
mains operation. To convert the Datapak for other mains
configurations they must be relocated or removed, following the
diagrams printed on the Front Panel and shown above.
Delta supplies:
In order not to exceed the rating of the terminal blocks, a supply
connection with two cables per phase is required. Connect one
cable to the upper phase terminal and the other to the lower phase
terminal.
All supplies:
When connecting your live phase cables be sure to re-connect the
ring connectors that take this supply to the front panel fuse holders.
The ring connectors must be in direct contact with the supply cable.
