2 Limited access (read) 1234
The passwords can be changed on the controller:
1. Go to Configuration mode.
2. Log on with password level 1.
3. Use the Up and Down buttons to go to Misc Settings, select with the Start button.
4. Use the Up and Down buttons to go to the password to be changed, select with the Start button.
5. Use the Up and Down buttons to choose the first digit for the new password, select with the Start button.
6. Repeat for the next three digits.
7. When all four digits are chosen, the display shows

2. Safety instructions
2.1 General safety instructions
This document includes important instructions that should be followed during installation and maintenance of the controller.
Installation and maintenance must only be carried out by authorised personnel, and always in accordance with all applicable state
and local electrical codes. Efficient and safe operation of the controller can be acquired only if the equipment is correctly operated,
configured and maintained.
The following notations found in this document can indicate potentially hazardous conditions to the operator, service personnel or
the equipment.
NOTE Highlights an essential element of a procedure to ensure correctness.
CAUTION
Indicates a procedure or practice, which could result in damage or destruction of equipment, if not strictly observed.
WARNING
Indicates a procedure or practice, which could result in injuring personnel or loss of life, if not followed correctly.
2.2 Electrical safety
• Electric shock can cause severe personal injury or death.
• Ensure that the genset is grounded before performing any installation or service.
• Generators produce high electrical voltages, and direct contact with it can cause fatal electrical shock. Prevent contact with
terminals, bare wires, connections, etc., while the generator and related equipment are running. Do not tamper with interlocks.
• To handle the maximum electrical current, the wires used for electrical connections and wirings must be of appropriate size.
2.3 In operation safety
• Before installing the controller, ensure that all power voltage supplies are positively turned off at the source. Disconnect the
generator’s battery cables and remove the panel fuse to prevent accidental start up. Disconnect the cable from the battery post,
indicated by a NEGATIVE, NEG, or (–) first. Reconnect the negative cable last. Failure to do so will result in hazardous and
possibly fatal electrical shock.
• Remove the electric power supply before removing the controller or touching other electrical parts.
• Use extreme caution when working on electrical components. High voltage can cause injury or death.
• With floors of metal or concrete, use rubber insulation mats placed on dry wood platforms when working near the generator or
other electrical equipment.
• Do not wear damp clothing (particularly wet shoes) or allow skin surface to be damp when handling electrical equipment.
• Do not operate any electrical device or wires while standing in water, while barefoot, or while hands or feet are wet. It may result
in severe electrical shock.
• Do not wear jewellery. Jewellery can cause a short circuit within electrical contacts and cause shock or burning.
In case of an accident caused by electric shock, immediately shut down the electrical power source. If this is not possible, try to
release the victim from the live conductor. Avoid direct contact with the victim. Use a non-conducting object (for example a rope or a
wooden stick) to release the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
