APC warrants its Panelmount SPD products against defects in workmanship and materials for 5

years from the date of original purchase. The panelmount SPD must be installed by a qualified

and licensed electrician in order to qualify for warranty protection.

Liability is limited to the replacement of the defective product. A Return Material Authorization

(RMA) must be given by APC prior to the return of any product (see Technical Support and

Customer Service). A copy of the invoice from the installer (electrician or electrical service

company) must accompany the defective device being returned. If the return of a device is

authorized by APC, APC will immediately ship a replacement unit to the customer. Along with

the replacement unit, APC will include a pre-paid shipping tag for the return of the originally

defective unit. The replacement unit will not be warranted unless the defective unit is received

by APC.

Under no circumstance is APC responsible for the cost of removal or installation of any panel-

mount SPD.

The company specifically disclaims all other warranties, expressed or implied. Additionally, the

company will not be responsible for incidental or consequential damages resulting from any

defect in any product or component thereof.

The panelmount SPD can be flush-mounted when the application requires a more aes-

thetic installation. To install the SPD using the FMK2, proceed as follows:

1. Ensure power to the panelboard has been removed.

2. Remove the screws securing the outer panelboard cover to the distribution panel-

board (panelboard) (see Figure 1).

3. Select the location where the SPD and Flush Mount Kit (FMK2) will be

mounted. The location should be based on the internal configuration of the panel-

board and the physical surroundings outside the panelboard). Note that the SPD’s

lead length must be minimized to achieve maximum performance. Aesthetics

may have to be sacrificed in order to achieve maximum surge protection.

4. Place the Flush Mount Kit panel where it will be mounted and trace the center

hole and mounting holes. Cut this shape into the mounting surface and mount the

FMK2 panel to the mounting surface.

5. Install the panelmount SPD to the backside of the Flush Mount Kit panel using

the four 8-32 x 5/8" Thread Cutting Screws (provided with the FMK2).

6. Drill or punch a 7/8" hole in the top, side or bottom surface of the panelboard in

accordance with the location of the FMK2.

7. Push the leads from the panelmount SPD through the 7/8" diameter hole toward

the inside of the panelboard.

8. Trim the leads from the SPD as short as possible, but still allowing the following

connections to be made (Note: Black wires go to the first 20 amp circuit breaker):

• Black wires (two or three in number) go to the nearest free circuit breaker. In

all installations, it is not critical which black wire goes to the positions on the

circuit breaker. The phase of each lead is marked with a white band and letter

designator (A, B, or C). Connect the SPD leads to the appropriate phase.

• Connect the white Neutral wire to the neutral bar using a set screw (in some

applications, this connection may not be required).

• Connect the green Ground wire to the panelboard ground.

9. Install the panelboard cover. Note: Conducting dielectric and/or high potential

testing will cause internal damage to the SPD unit. Do not perform dielectric or

high potential tests with the phase or neutral SPD wires connected.

10. Install any included warning labels near the panelmount SPD. Ensure the labels

are placed where they will be visible at all times.

11. Apply power to the panelboard. Depending on the PM 2 model, either 2 (split-

phase applications) or 3 (3 phase applications) LEDs will illuminate on the SPD.

If any connected phase LED on the SPD does not light, remove power, check all

connections and test again. If any connected phase LED still does not illuminate,

contact APC Customer Service at 1-800-800-4APC or APC Technical Support at

www.apc.com on the internet.
