INSTALLATION (CONT.):
3. CONDUIT FITTINGS
A ¾” NPT Offset style conduit nipple is provided as an integral part of the SPD on WM and
WMF models for routing the wiring pigtails into the electrical panel. Caution: Do not
attempt to remove, twist, turn or alter the integral conduit nipple. This will cause
irreversible damage to the SPD internal wiring and will void the warranty. An additional
conduit spacer, adapter or fitting should be used only when necessary to facilitate
installation.
For WM4 models, a dimensioned drawing is provided on page 12 showing the recommended
conduit entrance location. A UL-listed nonmetallic ½” liquid tight conduit fitting is
recommended to maintain the NEMA 4X rating of the enclosure. Note that the SPD unit may
be temporarily removed from the NEMA 4X enclosure to facilitate conduit installation.
4. POWER CONNECTIONS
Wiring pigtails are provided on the SPD for connection to the electrical power system. These
wires are #10 gauge stranded copper. Color coded black for phase connections, white for
neutral and green for ground. See page 14 for power connection location and identification.
5. WIRE ROUTING
The length of wiring to the SPD must be kept at a minimum for the best performance. Wire
lengths should be short, straight runs between the SPD and power source. Do not attempt to
splice into or lengthen the provided pigtails as this will result in reduced performance. Wiring
impedance can be further minimized by twisting the phase, neutral and ground conductors
together and routed in the same conduit, raceway or channel. Always avoid sharp bends
when routing SPD conductors.
6. CIRCUIT BREAKER
A dedicated 30 A circuit breaker (not included) is required to connect the SPD to the power
system.
7. REMOTE ALARM CONTACTS
Remote Alarm Monitoring Contacts are provided on all TR5000 SPD models. If this type of
monitoring is desired, refer to page 14 for the location configuration of these contacts. The
contacts are dry, 1 form C type, rated 125 VAC, 2 Amps maximum. Once the SPD has been
energized and is found to be operating normally, the alarm contacts will only change if there
is a failure within the SPD suppression circuitry, or if power has been disconnected from the
SPD. Leaving the Remote Alarm Contacts unconnected will not affect the performance of the
SPD. Alarm Cables can be spliced and lengthened to facilitate installations without concern
of reduced SPD performance.
8. PRE-ENERGIZATION CHECK
Once all of the pre-installation conditions have been met and the TR5000 SPD has been
installed, the SPD can now be energized. For SPD Operational Status, refer to Operation and
Maintenance Sections – pages 17 & 18.
