Wiring Instructions - Midas PRO6 Owner's Manual

28
• Ventilation: The PRO6 rack units have been designed such that their internal
ventilation airflow is drawn in through the front of the unit and expelled though the
rear. To facilitate this, rack design must ensure that cool air can flow freely through
the rack in the same direction, that is, in through the front of the rack and out
through the rear. Situations where the air flows in a circular direction around and
through a PRO6 unit must be prevented. Midas recommends that racks with fully
opening front and rear doors are used.
• Rack mount supports: Always secure the rear of the PRO6 units to the rack via
their rear rack mount support brackets. These brackets are fitted to every PRO6 unit
and are recommended for use in touring applications. The rack mount support fixing
hole centres are at a depth of approximately 395 mm from the front panel.
Note: The rack mount support fixing hole centre depth from the front panel of the
DN9696 Recorder may be slightly different.
• Handles on rack case: You must ensure that there are sufficient external handles
fitted to the rack casing to enable the rack to be manoeuvred easily and safely, and
by the amount of personnel suitable for the task. Also, these handles must be fit for
purpose.
• Clearance at rear of units: Ensure an adequate clearance at the rear of the units
to provide sufficient free space to enable the cables to achieve their minimum bend
radius.
• Securing the cables: We recommend that the cables at the rear of the units be
tidied using lacing bars and cable ties. This should provide optimum access to the
rear of the units for connecting other cables, switching the units on/off etc., and also
give maximum visibility of the units' LEDs for determining communication status,
link status, condition of audio etc.
Note: The above requirements also apply to any Midas and Klark Teknik units,
particularly the DN9696 Recorder and the DL4n1 units (used on the XL8).

Wiring instructions

Connect the snake (Cat 5e or fibre optic) to the DL371 Audio System Engine unit and
PRO6 Control Centre (see Figure 4 "Standard system configuration" on page 29).
The DL351 Modular I/O and DL371 Audio System Engine units should already be
connected together when you receive them.
>> To connect the PRO6 Control Centre to the DL371 Audio System Engine
1
At the rear of the PRO6, connect the fibre-optic or copper snakes to the optical
or copper connectors, respectively, in the snake X and snake Y sections.
2
At the rear of the DL371 Audio System Engine, connect the two snakes to the
appropriate connectors (optical or copper) in the snake X and snake Y
sections.
Caution!
Never combine units in the same rack that have been designed for
a ventilation air flow direction other than that designed for the
Midas units. To avoid this, we recommend that any non-Midas
units are housed separately.
