Installation Setup
11 Powerware ® 9170 User's Guide S LTM-1344 B Uncontrolled Copy
The cart requires no bolts or other hardware to fasten it to the UPS
cabinet. It is shaped to fit securely under the cabinet, ensuring proper
alignment after placing the cabinet on the cart.
Four foot pads under the cart keep the cart from rolling when it is in its
intended location. Turn each threaded foot to lower it to the floor.
When the foot is tight against the floor, turn the lock nut on the
threaded foot up tight against the bottom of the cart to keep the foot
from rotating.
If leveling of the UPS is required, use the foot pads to raise a side or
corner before locking them with their lock nuts.
Stabilizer Bracket Installation
The 12-slot Powerware 9170 UPS cabinet with non-isolated output is
shipped with two stabilizer brackets. These brackets must be attached to
the wall or the floor behind the UPS cabinet. Under all module-loading
conditions, they act as a protective stop to prevent the cabinet from
falling forward if it is unintentionally pushed away from the wall.
As shown in Figure 8, each bracket has holes that enable it to be
attached by screws to either the wall or the floor (or both) behind the
intended cabinet installation. The brackets are not attached to the
cabinet base itself. Install the brackets as follows.
1. Select the location for the brackets, approximately 12ć16I
(30ć41 cm) apart, at the floor/wall intersection behind the
intended cabinet location.
2. Using the proper type of customer-supplied screws for the
intended mounting surface, attach each bracket as shown in
Figure 8. All screws must be driven into structural material
such as wall studs.
3. Roll the UPS cabinet to its intended location, positioning the
rear section of the cabinet base under the open ends of the
stabilizer brackets, as far as the cabinet will go.
4. Turn all four caster bolts counter-clockwise until the cabinet
rests on the floor. Place a plastic cap into each bolt access hole.
NOTE If the floor is uneven and the cabinet is tilted or unstable, you may need to
place a thin steel plate under a corner. Do not use the caster bolts to level the
cabinet.
