6 Electrical Connection
☐ The signal generator for the fast stop (Fast Stop) can be designed as a break contact or make contact.
☐ With the exception of the signal generator for the Fast Stop function, all signal generators must always be
designed as make contacts.
Cable requirements for connecting a signal generator:
☐ Conductor cross-section: 1.5 mm² to 2.5 mm² (16 AWG to 14 AWG)
☐ Conductor type: copper wire
☐ Maximum cable length: 30 m (98 ft)
Terminal assignment:
Terminal
Function
X10:1 to X10:16
Digital outputs for the connection of signal generators
X10:17 to X10:36
Digital outputs for the connection of contactors
Procedure:
1. If a sufficient operating reserve of the genset cannot be ensured during a fast stop of the hybrid system and the
supply of the loads can thus be at risk, do not use any switching input for the Fast Stop function.
2. Insert the cable into the product (see Section 6.5.1, page 22).
3. Connect the insulated conductors in accordance with the customer-specific system circuitry (see Section 6.5.2,
page 23).
4. Ensure that the insulated conductors are firmly in place.

Periodic Actions
6.5.1
Inserting the Cables
Risk of injury due to escaping of hot fluids
In the event of a cable fire, hot liquid may be generated and escape through open knockouts underneath the
product. Escaping hot fluid may cause injuries.
• Ensure that all of the opened knockouts are used for the insertion of cables.
• Close unused knockouts with a suitable material.
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
• The product must not be opened in case of splashing water (e.g. from an irrigation system).
• Do not open the product during a dust storm or precipitation.
• Close the product in case of interruption of work or after finishing work.
• Only operate the product when it is closed.
• Store the closed product in a dry and covered location. Observe storage conditions.
• Only use the supplied cable glands when inserting cables.
• The temperature at the storage location must be in the specified range.
