4. Connect neutral conductor. The TDX units
are supplied with 10AWG leads. The white
Neutral conductor is 914mm (3ft) long. Wire
length should be minimized to improve
performance. There is no minimum wire
length requirement. Measure and trim the
neutral conductor to be as straight and short
as possible. Connect the neutral conductor
of the SPD to the neutral lug on the panel.
5. Connect phase conductors. All connection
leads should be cut to minimum length;
never coil or push aside excess length.
Multiple phase devices may be connected
without regard to phase A, B, C. With the
POWER OFF, connect each black phase
lead via:
a. 30 Amp circuit breakers. Use a multi-
pole circuit breaker, do not connect to
individual single-pole breakers for each
line.
b. or 30 Amp fused disconnected switch.
c. or if installed in compliance with Article
240-21, the NEC “tap rule”, over-current
protection may be omitted*.
* Note: In Australia, New Zealand and other
countries it is not permitted to omit over-
current protection.
The TDX units are supplied with 10AWG
leads. Phase conductors are 610mm (2ft)
long. Wire length should be minimized to
improve performance. There is no minimum
wire length requirement.
6. Nearby Attachment-Plug Receptacles
Any attachment-plug receptacles in the
vicinity of the filter are to be of a grounding
type, and the grounding conductors serving
these receptacles are to be connected to
earth ground at the service equipment or
other acceptable building earth ground such
as the building frame in the case of a high-
rise steel-frame structure.
7. Connector and Lugs
Pressure terminals or pressure splicing
connectors and soldering lugs used in the
installation of the filter shall be identified as
being suitable for the material of the
conductors. Conductors of dissimilar metals
shall not be intermixed in a terminal or
splicing connector where physical contact
occurs between dissimilar conductors unless
the device is identified for the purpose and
conditions of use.
8. Activate unit. When power is applied,
diagnostic light(s) will indicate that each
phase is protected. If light(s) do not
illuminate, recheck fusing, the phase, neutral
and ground connections.
9.
Flush Panel Mounting. For flush panel
mounting please order flush cover plate and
follow supplied instructions.
10. Problem Diagnostics. If problems continue
after checking the electrical connections,
contact your local ERICO representative.
11. No Neutral. For 480V Motor Control
applications with no neutral, use the TDX50
277/480, but do not connect the neutral
conductor (white conductor). The neutral
conductor should be capped/insulated
