2.5 RACK MOUNTING
The 1250 can be rack mounted in two ways: either by using fixed rails in the rack to
support the underside of the case, or by using telescopic slides to support the 1250 and
allow easy withdrawal for servicing.
With either method, the pair of rack mounting cars included in the accessory kit is
substituted for the finisher trims on the 1250; screws inserted through the ears and into
the rack keep the unit in place.
Note 1: The rack mounting ears must be used only to prevent the 1250 sliding out of the
rack. They are not designed to support the whole weight of the instrument.
Note 2: When the 1250 is rack mounted on telescopic slides, ensure that the rack will
not tip over when the slides are fully extended.
Two slide mounting kits are available as optional accessories:
1. kit 12505B (Accuride; UK), containing:
a. 1 telescopic slide kit, plus fixings
