Leviton 51110-PTC Installation Instructions

Transient voltage surges are short-term deviations from a desired voltage level or signal that can occur at
any time. Such changes can result in an electronic device malfunction, or cause extensive damage. Also
termed "spikes" , these occurrences take place as a result of magnetic field/inductive coupling or whenever
the line current is interrupted. They can originate from either inside a facility, or derive from outside utility
lines. Sources within a facility involve loads that are switched, such as electric motors that are turned ON and
OFF. Outside transient influences involve utility grid switching.
Leviton's 51110-PTC Residential Panel Surge Protection Device (SPD) is a high-performance Transient
Voltage Surge Suppressor. The Residential Panel SPD unit is designed for use on 120/240VAC at the
RESIDENTIAL PANEL SURGE home's breaker panel. The SPD panel also houses protection circuits for telephone/modem line protection, a
CATV SPD circuit and a satellite circuit SPD. Diagnostics provide visual indicators for monitoring the

providing a short suppression path, which optimises the clamping capability of the SPD.
TO INSTALL

serving the loads to be protected, to minimize the effects of connection lead-length resistance and
inductance.
NOTE: Matching the TVSS model and electrical system line voltage is critical! Identify the system to be
protected by measuring L-N and L-L voltages. Use extreme caution while making voltage measurements!
If you are unsure of the type of electrical system in use, or the system voltage, stop and contact a qualified
electrician.
Confirm that the maximum measured voltage does not exceed the maximum continuous line voltage
specified for the 51110-PTC unit to be installed or damage will occur. Figure 1 illustrates the wiring
connection for the 51110-PTC.
5. Remove SPD cover to provide wiring access. Leads from the SPD must be connected to the power mains
through a 30 Amp (maximum) disconnect and fusing means. Either dedicated branch circuit breakers
(independent single-pole preferred), or a fused disconnect switch may be used. When the SPD device
shares a 2-pole ganged breaker, National Electric Code (NEC) and local requirements shall prevail.
NOTE: Sharing of breakers is not permitted by CEC in Canada.
NOTE: For best performance, installation wires should be twisted or bound together and as short as
possible. For optimal performance, connection wires longer than 12 inches should be avoided.
Leads from the SPD should be bundled together and secured with cable ties when possible. Conduit shall
be used where required by code. For best suppression, the cable and some cable ties may be cut down
from the supplied length to allow for a shorter installation path.
6. Mount the SPD unit securely. The 51110-PTC unit can be surface, stud or conduit mounted and has 2
removable mounting flanges on it's back. When the flanges are removed from the SPD unit back, they can
easily be side mounted by re-attaching them (using the same screws) to the top and bottom portion of
either side of the SPD (side holes provided). Side mounting flanges would be used to provide "stud
mounting" to a vertical support from the side and they would be used for flush mount applications. When
mounted in this manner, the Input and Output telephone wires would both need to be routed through the
same (unblocked) knockout hole and properly strain relieved. If flush mounting, install the flush mount
cover over the top of the standard cover and secure with the standard cover screws. Direct panel
mounting applications ("conduit mounted") should utilize a 3/4" conduit knockout hole with the dual
threaded nipple (provided).
7. When attaching the SPD connection leads to the power lines, first insert conduit fitting provided (or use
equivalent) into top knockout hole to protect insulation/wires. All four connection leads from inside the
SPD should be routed through the conduit fitting to the outside of the SPD. Then, the wires should be
routed to the circuit breaker terminals (refer to Figure 1) using the shortest path (cutting excess wire
length) to the power line. Use conduit, as required, by National Electric Code (NEC) and local
requirements. Avoid sharp bends. Lead wire insulation should not be cut or damaged.
8. Connection: Connect the Black wire (marked "Line 1") to one line, and the other Black wire (marked
"Line 2") to the other line. These Black wires may be connected to either L1 or L2 without regard to phase
angle.
9. The White wire should be connected to the system's Neutral bus.
10. The Green wire is attached internally to the 51110-PTC unit's metal enclosure. The Green wire must be
grounded to the electrical panel's ground bus.
11. Check that all connections are correct, tight, and secure.
FOR TELCO:
WARNING: NEVER INSTALL TELEPHONE WIRING DURING A LIGHTNING STORM.
NOTES:
1. Disconnect telephone line at the network interface before installing the secondary protection.
2. This SPD unit is intended for Indoor Use Only.
INPUT WIRING:
1. Figure 2 shows telephone wiring using a maximum of 2 lines. Re-route telephone Service Untwisted
Shielded Pair (UTP) wires to directly enter the home and connect to the SPD unit "INPUT". Additional UTP
wire may be required.
2. Remove AC power to the SPD.
3. Remove the SPD cover to provide access to the telephone connection screw terminals.
4. The incoming telephone service wires are typically a UTP (or Category 5) wire composed of 2 or 4
multicolored pairs of insulated wire. Each telephone line requires one multicolored pair of wire. Remove
approximately 6 inches off the end of the outer jacket of the telephone wire and determine the number and
color of the pairs of wires inside.
NOTE: A maximum of two telephone lines (2 pairs of wires, refer to Figure 2) can be connected to the
SPD.
5. Insert bushings (provided) into the knockout hole to protect insulation/wires. Torque screws on strain relief
to 10 +/- 2 in.-lbs. If unit has been stud mounted, both Input and Output telephone lines must be routed
through the same (unblocked) knockout hole and properly strain relieved with the bushing provided.
6. Seperate the colored wire pairs and fasten to the screw terminal "INPUT" as shown in Figure 2.
7. Tighten screws using 3.5 in-lbs. of torque. Repeat procedure for up to 2 pairs of wires.
