Deif PPM 300 - Warnings and Safety; Safety During Installation and Operation; Disable the Breakers; Disable the Engine Start

1.2 Warnings and safety
1.2.1 Safety during installation and operation
Installing and operating the equipment 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
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.
1.2.3 Disable the engine start
Disconnect or disable or block the engine start (the crank, and, if present, the run coil) 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.
1.2.4 Metal fragments and other objects
Do not allow metal fragments or other objects to fall into the controller rack or display unit. Be especially careful during installation,
for example, when shortening wires.
To prevent metal fragments from falling into the controller rack, it is recommended to place a cover over the top ventilation holes of
the controller rack. The controller is supplied with a disposable cover to protect it from metal fragments and other objects during the
first installation.
CAUTION
Keep metal fragments out of the controller. Metal fragments can damage the controller.
CAUTION
Remember to remove the cover for the controller rack ventilation holes after work has been completed. Failure to do so can
damage the controller.
1.2.5 Electrostatic discharge
You must protect the equipment terminals from electrostatic discharge when not installed in a grounded rack. Electrostatic discharge
can damage the terminals.
