Instruction Bulletin
DANGER
HAZARD OF ELECTRIC SHOCK, BURN OR EXPLOSION.
• This equipment must be installed and serviced only by qualified electrical
personnel in accordance with National and Local Electrical Codes.
• Turn off all power supplying this equipment before working on or inside
enclosure containing this equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors, and covers before turning on power to this equipment.
Failure to follow these instructions will result in death or serious injury.
Not for use on ungrounded systems.
Failure to follow these instructions can result in death or serious injury.
WARNING
HAZARD OF EQUIPMENT DAMAGE.
• Megger
®
or hi-potential tests will damage this surge protective device. Turn off
all power supplying the equipment and isolate the surge protective device before
testing.
• Must be installed with provided class CC fuses.
Failure to follow these precautions can result in equipment damage.

INSTALLATION
1. Turn off all power supplying this equipment before working on or inside
enclosure containing this equipment.
2. See Figure 1, 2 for mounting instructions.
NOTE: The surge protective device must be installed in an accessible location
(not within walls).
3. Confirm the SPD is rated for your system by comparing voltage
measurements to the Line Voltage (L-L, L-N) on the product label.
4. Install in accordance with National and Local Electric Codes and match
branch circuit breakers to the size of wire being used (#10 AWG, up to 30 A).
5. Confirm that the electrical terminals used to attach this device are
identified for these conductors.
6. Install class CC fuses (provided) into fuse holders, if they are not already
installed (See Figure 3). Do not substitute fuse, use only the provided
class CC 30 type fuses.
NOTE: These protectors or fuses do not replace the need for branch circuit
protection as stated in step 4 above.
7. Twist conductors 1/2 turn or more for every 12 inches of length.
8. Keep conductor length as short as possible with no sharp bends.
9. Do not loop or coil wires.
Be sure to maintain adequate wire bending space
per NFPA 70 2002 Edition, article 408.35.
10. Use on solidly grounded systems only.
11. Install cover and/or close door on equipment.
12. Apply power. If all three lights not on, go to diagnostic operation.
Diagnostic Operation
• LED ON = Normal operation (see Figure 4).
•LED OFF (one or more) and/or Audible Alarm ON = Fault. Check phase
voltage on line side of fuse, circuit breakers and connections. If OK replace
TVSS unit and all associated fuses and fuseholders.
• If fuses open, replace TVSS unit and all associated fuses and fuseholders.
• Remote Monitoring (Dry Contacts). A three-pin socket and plug are provided
to allow the user to wire one set of normally open (NO) and normally closed
(NC) Dry Contacts to a remote monitor. The user must provide power for the
remote monitor, keeping within the specifications shown in Figure 4.
The SPD’s internal electrical relay energizes when AC power is applied and
de-energizes in event of a fault within the SPD or removal of power from unit.
NOTE: The supplied three-pin plug can accept up to #16 AWG (1.5mm
2
) wire.
