ALERT !
ALERT! This equipment is designed to permit connection of
the earthed conductor of the dc supply circuit to the earthing
conductor at the equipment. If this connect is made, all the fol-
lowing conditions must be met:
z This equipment shall be connected directly to the dc supply
system earthing electrode conductor or to a bonding jumper
from an earthing terminal bar or bus to which the dc supply
system earthing electrode conductor is connected.
z This equipment shall be located in the same immediate area
(such as adjacent cabinets) as any other equipment that has a
connection between the earthed conductor of the same dc sup-
ply circuit and the earthing conductor, and also the point of
earthing of the dc system. The dc system shall not be earthed
elsewhere.
z The dc supply source is to be located within the same pre-
mises as this equipment.
z Switching or disconnecting devices shall not be in the
earthed circuit conductor between the dc source and the point
of connection of the earthing electrode conductor.
The MIX 56 chassis mounts into standard 19- inch (48.3 cm) or 23-inch
(58.4 cm) WECO and EIA racks. A 23-inch rack installation requires the
extender bracket.
A single MIX 56 chassis requires 5.25 inches of vertical space (the height
of the chassis). When installing one chassis on top of another, install a heat
baffle of at least one rack unit above and below the pair, as shown in the il-
lustration on the next page. Telect recommends heat baffles below each
MIX 56: for a 19-in. rack, order part # 747-9999-0019; for a 23-in. rack,
order part # 747-9999-0023.
