Drawmer HQ-r Remote - Manual (Page 4)

4 DRAWMER HQ O
PERATOR’S M ANUAL
The unit will have been supplied with a power cable
suitable for domestic power outlets in your country.
For your own safety it is important that you use this
cable. The unit should always be connected to the
mains supply earth using this cable, and no other.
If for some reason the unit is to be used at a mains
input operating voltage which is different to that as
supplied, the following procedure must be carried out.
1: Disconnect the unit from the mains.
2: Remove the two screws holding the voltage
selection cover-plate.
3: Remove the cover plate and slide the switch
fully to its opposite end.
4: Rotate the cover plate one half turn (180 degrees)
and refit the two screws.
5: Replace with a correctly rated fuse for the
selected operation voltage in the IEC socket:
230V-T1A and 115V-T500mA
6: Re-connect to mains power source.
Never disconnect the earth
from the mains supply
When you unpack your HQ you will notice that it has been
fitted with both the rack ears and feet attached, to help
during carriage, however, it has been designed so that it
can be installed in a rack or free-standing. If it is to be free-
standing, in a cabinet for example, the rack ears can be
detached by removing the four screws that locate each ear
(see fig. 01), whilst leaving the feet in place.
If it is to be located in a rack detach the four feet underneath
the unit by removing the four screws. If replacing the feet
at some time ensure that the two locating pins on each
foot line up with the holes on the unit before tightening the
screws (see fig.02). The HQ will fit into a standard 19" rack
mounting and occupies 2U of rack space. Fibre or plastic
washers may be used to prevent the ears becoming marked
by the mounting bolts.

INSTALLATION
Avoid mounting the unit directly above power amplifiers or
power supplies that radiate significant amounts of heat. In
addition, if in a rack, it is advised that you leave at least 1U
of space above to allow heat to dissipate. Alternatively, a
fan should be fitted somewhere near to the rear of the unit
to circulate cooler air and help expel any excess heat.
Any ventilating holes should remain unblocked at all times.
