TDX100 & TDX150 Series

The CRITEC TDX100 and TDX150 Series of Surge Protection Devices (SPD) are high-performance transient voltage surge

suppressors (TVSS), designed to provide protection to service panels, load centers or where the SPD is directly connected to

the electronic device requiring protection. Maximum protection will only be achieved if the SPD is properly installed. Please

read the following installation instructions carefully and follow the instructions.

DANGER: Electrical shock or burn hazard. The installation of this TVSS device should only be made by

qualified personnel. Failure to lockout electrical power during installation or maintenance can result in

fatal electrocution or severe burns.

CAUTION: Check to make sure system voltages do not exceed the TVSS voltage requirement and the

correct TVSS voltage/model has been selected.

CAUTION: This unit must be installed in accordance with the National Electrical Code (ANSI/NFPA-70)

and applicable local codes, and must be installed on the load side of the main over-current protection.

CAUTION: Do not install on ungrounded electrical systems.

NOTICE: Do not cut wires until the SPD is mounted and minimum wire lengths have been verified. All connection leads

should be cut to minimum possible length; never coil or push aside excess length.

INSTALLATION INSTRUCTIONS

1. Verify system voltage by measuring L-N, L-G, L-L

and N-G of the system. Confirm that the SPD is

correctly rated for the system to which it is to be

connected by comparing the measured voltages to

the SPD voltage ratings shown on the product label.

The (MCOV) maximum continuous operating voltage

specifications must not be exceeded.

2. Identify proper location for the SPD. Locate the unit

as close as physically possible to the panel being

protected and as close to the electrical connection as

possible so as to avoid excess lead lengths and the

need for sharp bends in the wires. (Note: Refer to

installation diagram on SPD.). Mount top and bottom

SPD flanges securely. Use appropriate cable glands

to preserve the SPD/panel NEMA enclosure rating.

3. Connect proper ground. An insulated grounding

conductor that is identical in size and insulating

material and thickness to the grounded and

ungrounded circuit supply conductors, except that it is

green with or without one or more yellow stripes, is to

be installed as part of the circuit that supplies the

filter. The TDX is supplied with 914mm (3ft) long of

#10AWG, in accordance with Table 250-122 of the

National Electrical Code, for this purpose. The

housing of the TDX unit is bonded to the grounding

conductor for equipment safety ground purposes as

per National Electrical Code. The grounding

conductor is to be grounded to earth 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.

Attach the grounding conductor to the panel’s ground

bus for proper operation. Wire length should be

minimized to improve performance. There is no

minimum wire length requirement.

Note: For isolated ground systems, bond the

grounding conductor from the TDX unit to the non-

isolated equipment ground, not the isolated

equipment ground.

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. The phase wires may

be connected without regard to phase A, B*, C

orientation. 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.
