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 Handbook 44
provisions both for AC and DC.
For complete freedom and test automation use, the PL4000 Load Emulator, a dedicated
programmable load 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.
1.2 Contacting TESCO

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 TS400 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.

2.1 Introduction
This chapter provides instructions for unpacking and installing the Instruments.
Read this chapter before you operate the Instrument. Instructions for cable connections can be
found here.
2.2 Unpacking and Inspection
The testing equipment is shipped in a container designed to prevent damage during shipping.
Inspect the Instruments carefully for damage, and immediately report any damage to the shipper.
A packing list is included in the packaging. When you unpack the Instruments, check for all the
standard equipment listed and check the shipping order for any additional items ordered. Report
any shortage to the place of purchase, to your distributor, or directly to TESCO.
2.3 Setup, Airflow and Cooling Considerations
2.3.1 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. The Instruments can be vertically oriented as well. Please see
suggested placement per setup.
Figure 2.3a 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.

SETUP & INSTALLATION
2.3.2 Airflow
WARNING
Note of the Instrument’s airflow as indicated in the illustration below. 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.
2.3.3 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.

2.4 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 EV charger.
CAUTION
Only charge the unit with approved power supplies.
2.5 Connection 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 maintains ground
until after power connections are broken. This system helps ensure a safer connection.

SETUP & INSTALLATION
2.5.1 Sequence of Test Connection and Power-Up
1- Connect the COMBITAC of
PL4000 to the LOAD AND
