1.1 Introduction
TESCO’s CAT. TS400 Electric Vehicle Service Equipment (EVSE) Test System is a complete
system that consists of the CAT. T4000 EVSE Tester and the CAT. PL4000 Programmable
Load, which tests the accuracy of energy delivery using a transactional mode compatible
with HB44 provisions both for AC and DC.
For complete freedom and test automation, add the PL4000 Programmable Load, a
dedicated load emulator solution providing no-load and adjustable-load modes. Any
compatible EV can also be used as the test load by using the appropriate optional cable.
The Proximity and Pilot Control signal exchanges are fully verified for compliance with
protocol requirements. The EVSE’s GFCI can also be tested by applying a programmable
line-earth fault current up to 200mA.

1.3 General Safety Summary
This manual contains information and warnings that must be observed to ensure safe operation
and keep the TS400 in a safe condition. Operation or service in conditions or in a manner other
than specified could compromise safety. For the correct and safe use of this device, it is essential
that both operating and service personnel follow accepted safety procedures in addition to the
safety precautions specified, including PPE guidelines.
In this manual, a WARNING identifies conditions and actions that pose hazard(s) to the user, while
a CAUTION identifies conditions and actions that may damage the T4000 or the test equipment.
WARNING
To avoid electrical shock, personal injury, or fire hazard:
•Both devices, T4000 and PL4000 must not be switched ON if it is damaged or
suspected to be faulty.
•Do not operate the device in wet, condensing, dusty, or explosive gas conditions.
•If the equipment is used in a manner not specified in this manual, the protection
provided by the T4000 and the PL4000 may be impaired.
•Whenever it is likely that safety protection has been impaired, the devices must be
made inoperative and be secured against any unintended operation. Inform qualified
maintenance or repair personnel.
•Safety protection is likely to be impaired if, for example, the T4000 displays visible
damage or fails to operate normally.

1.8 Set up, Airflow and Cooling Considerations
1.8.1 Setup and Placement
The Instruments are designed to be used sitting on the ground, as long as there is sufficient space
to allow adequate ventilation.
Figure 1.0 Suggested TS400 Setup sitting on the ground.
WARNING
PL4000 air outflow can be extremely hot particularly when testing at higher load current or power.
Please allow a separation distance between the T4000 and PL4000 of at least 2 feet (0.7 meters)
making sure that the COMBITAC cable doesn’t obstruct air outlet.

1.8.2 Airflow
WARNING
Note of the Instrument’s airflow as indicated in the illustration below. This is applicable for both
bench top and rack-mounted use.
PL4000 air outflow can be extremely hot particularly when testing at higher load current or
power. Please allow back space of at least 6.5 feet (2 meters) for the PL4000 air outflow.
Figure 1.1 TS400 Airflow
1.8.3 Cooling Considerations
CAUTION
Damage caused by overheating may occur if the area around the air intake is restricted, the
intake air is too warm, or the air filter becomes clogged.
The inlet and exhaust holes must be clear of obstruction. The air entering the instrument must
be between -4° F (-20° C) and 122° F (50° C). Make sure that exhaust from another instrument is
not directed into the fan inlet. Check and clean the air filter every 30 days or more frequently if
the Instrument is operated in a dusty environment.

1.9 Main and Auxiliary Power Supply
The Instrument is powered by an internal rechargeable battery. The battery charge status icon
can be seen in the top right corner of the T4000 LCD screen. The battery can be easily removed
and replaced in the field with a spare one (sold separately).
The battery can be charged in the unit using the provided auxiliary power supply which requires
a 120 VAC outlet. A car charger and a desktop charger (for external charging) are available as
additional accessories.
WARNING
To avoid electrical shock, personal injury, or fire hazard, connect the factory supplied power
cord to a properly grounded AC power outlet to charge the unit when not being used with an
EVSE charger.
Do not charge the unit when it is connected to an EVSE charger.
CAUTION! Only charge the unit with approved power supplies.
1.10Connection and Power-Up
The instrument’s connector employs a “make first, break last” system where upon insertion, the
ground connection is established first before making power connection and maintain ground until
after power connections are broken. This system helps ensure a safer connection.
1.10.1 Sequence of Test Connection and Power-Up
1- Connect the COMBITAC of
PL4000 to the LOAD &
CONTROL connector of T4000.
2- If connected, unplug the AUX
power supply. Then, connect
the Coupler of EVSE to the
J1772 connector of T4000.
3- To Power ON, press the POWER
button for at least 2 seconds.
