OUNTING
Figure 4 shows the SHARK™ IAD unit mounted to a wall which requires the
special mounting hinge (which must be ordered separately, see Figure 5) and
hardware supplied with the unit. Be sure that the mounting board onto which the
unit is mounted is at least 3/4 inches thick. Use Size 12 pan head screw
minimum length of 3/4 inch to secure the unit to the mounting board. Mount the
unit as shown in Figure 4.
Route the cabling along the rear of the unit near the hinges. Secure the cables to
the wall and the unit as shown in Figure 4. Do not obstruct the vent holes on
upper side of the unit with the cabling. Be sure to provide service loops in the
cable to allow the cabling to swing away from the wall with the unit. This will
provide stress relief for the cables when the unit is swung away from the wall.
Routing the cables in this manner allows the cables to twist near the hinges along
the width of the unit.
Any other routing method may force the cables to bend causing metal fatigue of
the conductors. Dressing the cable bundles in this manner will also allow
maximum unrestricted access to the front of the unit.
If the AC/DC converter is required, mount it to the mounting board using
number 10 pan head screws that are a minimum length of 3/4 inch.

ROUNDING
To ensure proper EMI shielding, the grounding scheme must be taken into
serious consideration when installing the SHARK™ IAD. The unit is equipped
with a threaded grounding lug. For ALL installations, this grounding lug must
be attached to facility chassis or safety ground. The grounding lug is located on
the rear of the unit.

A DC cable is available for applications where -48 DC is available. This cable
is approximately 10 feet long with a Molex connector on one end that mates to
the power module's power input connector. The opposite end has pigtails with
ring terminals that are used to connect to a power distribution panel with
terminal strips or terminal blocks.
The complete definition is located in the cable guide chapter of this manual;
reference part number 9SA-00DC-CBL.
Pigtail end:
Red connect to -48 DC
White connect to Frame ground
Black connect to -48 return
The bare wire that is covered with heat shrink is the shield drain. Connect it to
the facility chassis ground or safety ground.
