Always approach the truck from the sides to stay out of the
potential travel path. Due to lack of noise it can be difficult to
determine if the truck is running.

1. Traction Battery: Four Li-ion battery packs supply a
maximum of 738V at 110A. Battery electrodes are made of
Carbon, Lithium, Nickel, Manganese and Cobalt.
2. Charging switch unit (CSU): The primary function of the
Charging Switch Unit (CSU) is to act as a circuit breaker for
the charging plug.
6
3. DC/DC converter: The DC/DC converter converts the
traction voltage of 600 V DC to 24 V DC. In electric trucks, the
DC/DC converter charges the 12 V batteries and handles the
loads connected to the 24 V system.
4. Traction Voltage Junction Box (TVJB): The TVJB has 2
variant combinations depending on the number of
high-current and low-current connection interfaces.
The TVJB distributes power in the electric propulsion system.
5. Electric Motor Drive (EMD): The EMD converts 600V DC
to three-phase AC. The EMD runs the electric motor and
controls the speed, torque and calibration.
8. Electric Motor: 2 three-phase AC motors with 400kW to
334 kW capacity power the truck.
9. Electric motor, hydr. ePTO: Three-phase Ac motor with
70kW power the hydraulic pump.
10. Electric Motor Drive (EMD)- hydr. ePTO: The
EMD- ePTO converts 600V DC to three-phase AC. The EMD
runs the electric motor and controls the speed, torque and
calibration.
6. Charging inlet, CCS 1 type : The CCS inlet is used for
600V DC charging. The CCS inlet is equipped with an
actuator that prevents accidental disconnection of the
charging plug on truck side.
7. Traction Voltage Monitoring Unit (TVMU): The TVMU
performs measurements in the traction voltage system,
detects any potential hazardous situation and communicates
this to the HPCU (Hybrid Powertrain Control Unit).

ABC
Use a large sustained volume of water to extinguish lithium-ion battery related fire.
If other materials are involved, use class ABC fire extinguisher.
In case of thermal runaway, the lithium-ion batteries can
release hydrogen fluoride.
The damage level of a submerged vehicle may not be visible.
Submersion in water can damage 12 V, 24 V and 600 V components.
Handling a submerged truck without appropriate Personal Protective Equipment (PPE) may result in
serious injury or death due to electric shock.
Avoid any contact with the traction voltage cables and electric components.
If possible disable direct hazards (See chapter 3).
In case of traction battery fire, breather valves (1) may emit
large flames as a result of thermal runaway.

IR
Park the fully electric truck involved in an accident in a suitable place maintaining a safe distance from
other vehicles, buildings and combustible objects.
Risk of delayed fire can happen after the fire suppression or if the lithium-ion batteries are damaged.
Observe the truck for a minimum period of 48 hours using a thermal infrared camera.
If the traction batteries are damaged, there is a risk of thermal or chemical reaction.
The electric motors can produce electricity when moving
the truck with the rear drive tires on the ground.
This remains a potential source of electric shock even
when the high voltage system is disabled.
Before towing the truck, it is mandatory to disconnect
the drive to the wheels. The drive to the wheels is disabled
by either uncoupling the propeller shaft (1) from the driven
axle (2) or by removing the axle shafts (3).

Note
When the vehicle is towed with the rear suspension lifted, the steering
wheel must be locked with the steering lock.
3
Note
If roof deflectors cannot be removed, tow from the front of vehicle only.
Maximum loading during lifting and towing:
This informaon specifies the loading which can be applied when
using towing hook, towing hitch cross-member, axles and torque stay
anchorages.
• Lengthways: 20 tons
• Vercally (li): 7 tons
• Sideways: 17 tons
Single towing hook: Do not load the hook more than the
vehicle gross weight.
Double towing hooks: Do not load each hook more than half
the vehicle gross weight.
Towing hitch, towing Hitch Cross-Member: Max. 200 mm
(7.8 inches) from center of member web

Do not cut any orange cables.
Do not touch any high voltage cables and electric components.
Do not perform any operation on a damaged truck without appropriate Personal Protective Equipment
(PPE).
