Time Tagger X safety notice

Swabian Instruments’ Time Tagger X is a high-resolution streaming time-to-digital converter in a 19-inch rack mountable housing. This section gives further information on the Time Tagger X and its operation.

Electrical characteristics

Power supply ratings
Parameter	Value
Voltage	100 - 240 V AC
Frequency	47-63 Hz
Power	max. 60 W

The maximum voltage and current ratings of the signal inputs and outputs are specified on the Time Tagger X’s housing and must not be exceeded. The details on the characteristics of the input channels can be found in the dedicated section Input channels.

Equipment installation

The Time Tagger X does not require assembly and is supplied fully assembled. It can be installed as a table top instrument or in a standardized 19-inch rack. Any operating position shall provide adequate space for cable connections and air circulation.

A table top installation requires an even and horizontal surface with enough space for easy access to the device.

Installation in a standardized 19-inch rack requires 2 height units. The rack shall provide sufficient ventilation and must not obstruct the ventilation openings of the Time Tagger X’s rear panel.

Position the Time Tagger X in a manner that allows the user to disconnect the device from the mains at any time and without restrictions.

Before connecting to the mains, inspect the product and the power cord for visible damage. Connection to the mains shall be done only with the supplied detachable power cord. In case of doubt, do not operate the product and seek assistance from a qualified electrician or a person responsible for electrical safety.

Safe operation can no longer be assumed:
- after rough handling during transport or installation,
- in case of visible damage to the product or its power cord,
- in case of loose internal parts being noticed,
- in case of ingress of any liquids inside the product’s housing.

The Time Tagger X provides one functional ground terminal on the rear panel located next to the power cord receptacle. All connectors that feature ground terminals are electrically connected to the Time Tagger X housing and to the functional ground terminal. This includes shield terminals on the SMA connectors and the USB-C connector.

Take care of appropriate grounding practices and ensure that all connected accessory and equipment shares common ground with the Time Tagger X. Connection of additional accessories or equipment that are grounded to an independent grounding circuit has the potential risk of electrical shock. An inappropriately grounded Time Tagger X and/or connected equipment may result in product damage, malfunction, degraded performance or poor signal quality.

After connecting the Time Tagger X to the mains, it will be in a “Standby” power mode, as indicated by the power button light pulsating blue. Press the power button to switch the product into the “Ready” state - the power button light will turn green. By pressing the power button again, the Time Tagger X can be switched back into the “Standby” power mode.

The Time Tagger X produces waste heat during regular operation. Long-term continuous operation at elevated environment temperatures may lead to a warm product surface, this is not a malfunction. Stop operation immediately and contact the manufacturer in case the product’s surface temperature exceeds 55 °C (hot on brief touch).

Maintenance and repair

The Time Tagger X does not contain any user-serviceable or user-repairable parts. In case of malfunction or damage, stop operating the Time Tagger X, disconnect it from the mains and contact the manufacturer.

The Time Tagger X may only be opened by personnel authorized by the manufacturer.

Disconnect the Time Tagger X from the mains before opening it and working on the internal components. Otherwise the personnel may be exposed to the risk of electric shock.

Adjustments, replacements of parts and repair may be carried out only by personnel authorized by the manufacturer.

All Time Tagger X units repaired by the manufacturer undergo verification and testing procedures in the same way as new units. The electrical safety of every new and repaired Time Tagger X is verified with a Gossen Metrawatt SECUTEST PRO testing instrument.

Power cord

The detachable power cord must be adequately rated for the operation voltage and power consumption of the Time Tagger X, see the table Power supply ratings.

It is strictly forbidden to use a damaged power cord or a cord with inadequate ratings. In case of doubt, do not operate the product and contact the manufacturer or seek for assistance from a trained electrician or a person responsible for electrical safety.

Safety fuse

The Time Tagger X is equipped with a mains fuse located on the rear panel beneath the power cord receptacle. The fuse compartment can only be accessed when the power cord is detached from the Time Tagger X. The fuse type and fuse rating must comply with the specification in the table Safety fuse ratings and the labeling on the Time Tagger X.
