1.2 Warnings and safety
1.2.1 Safety during installation and operation
Installing and operating the controller may require work with dangerous currents and voltages. The installation must only be carried
out by authorised personnel who understand the risks involved in working with electrical equipment.
DANGER!
Hazardous live currents and voltages. Do not touch any terminals, especially the AC measurement inputs and the relay
terminals. Touching the terminals could lead to injury or death.
1.2.2 Disable the breakers and the engine start
Disconnect or disable the breakers before connecting the controller power supply. Do not enable the breakers until after the wiring
and controller operation are thoroughly tested.
DANGER!
Unintended breaker closing can cause deadly and/or dangerous situations.
Disconnect or disable or block the engine start before connecting the controller power supply. Do not enable the engine start until
after the wiring and controller operation are thoroughly tested.
DANGER!
Unintended engine starts can cause deadly and/or dangerous situations.
1.2.3 Factory settings
The controller is delivered pre-programmed from the factory with a set of default settings. These settings are based on typical values
and may not be correct for your system. You must therefore check all parameters before using the controller.
1.2.4 Electrostatic discharge
Electrostatic discharge can damage the controller terminals. You must protect the terminals from electrostatic discharge during the
installation. When the controller is installed and connected, these precautions are no longer necessary.
1.2.5 Data security
To minimise the risk of data security breaches DEIF recommends to:
• As far as possible, avoid exposing controllers and controller networks to public networks and the Internet.
• Use additional security layers like a VPN for remote access, and install firewall mechanisms.
