Installation Setup

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 12￿16￿

(30￿41 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.
