§ Remove watches, bracelets, rings or other conductive objects before the operation. Wear special gloves for protection against electrostatic hazards. Failure to comply can result in damage to equipment.
§ Never set heavy objects on top of the cabinet. Failure to comply can result in damage to equipment.
§ Always use insulated tools when making electrical connections and always ensure that all connection terminals and unnecessarily exposed metal parts are fully insulated. Failure to comply can result in damage to equipment.
§ The system has high leakage current, thus it must be properly grounded before power-on. The grounding cable should be connected to the nearest grounding terminal, and the cable length cannot be greater than 30 m.
§ Battery requirements:
· Batteries used in the system should be of the same type. Old and new batteries must not be used together.
· Battery packs should not be short-circuited in any way during the operation.
§ Cable requirements:
· Cable diameter: The diameter of a cable should match the load capacity.
· Cable color: When using cables in non-standard colors, use black cables and mark them using heat-shrinkable tubing or insulated tape in corresponding colors to avoid errors. If local regulations have different requirements for cable colors, always follow the local regulations. Failure to comply can result in damage to equipment.
· Cable bending radius: At a corner of a cabling route, the turning radius should be 10 times equal to or greater than the cable diameter to avoid short circuits due to the cable tube damage caused by the turning radius being too small.
Check Criterion: An alarm sound given by the multimeter indicates that there is a
short circuit! Locate any short circuit and eliminate it before proceeding to the next step.
Example:
Check for short circuit between
L1 and N.
Ensure that all power is removed
prior to performing the check.
Failure to comply can result in
damage to the multimeter.

Electrical check must be performed before system commissioning, to avoid
equipment damage caused by cable connection errors.Caution
1.2 Checking DC Output for Short Circuit
Steps
1. Set the AC output circuit breaker (in the AC power distribution box) to ON position.
2. Check rectifiers individually.
(1) Install rectifier 1 into the slot SMR 1.
(2) Set the AC input circuit breaker (in the ZXDU68 G020 cabinet) to ON position.
(3) Observe the rectifier indicators to ensure that the rectifier is operating properly.
(4) Set the AC input circuit breaker (in the ZXDU68 G020 cabinet) to OFF position.
(5) Pull the rectifier outward for about 30 mm to shut down the rectifier.
(6) Repeat the steps (1) - (5) to check the rectifiers (SMR 2 and SMR 3) and ensure
that the rectifiers are operating properly.
3. Push the rectifiers into the corresponding slots until well seated.
4. Set the AC input circuit breaker (in the ZXDU68 G020 cabinet) to ON position to power
all the rectifiers.Starting CSU3
Steps
1. Install the CSU.
2 Make sure that the CSU is operating normally by referring to “Status Indication”.
Status Indication:
After the CSU self-check and initialization, the LCD displays
the main menu screen. The DC output branches and battery
branches are open, so the CSU activates the following
alarms:
§ LLVD1 Loop Brk.
§ BLVD Loop Brk.
§ Batt.Loop Brk.

1.4 Checking Terminal Voltage of the Battery Pack
1. Turn the knob of the multimeter to the DC voltage scale.
2. Measure the terminal voltage of the battery pack and record the value in the table below.
A negative measured value indicates that the positive and negative battery cables are reversed. Re-connect the cables!
Check Criterion:1. The voltage of the battery pack should be
a positive value.
2. The voltage of the battery pack should not be lower than 43.2 V (the value is for reference only). If the voltage does not meet the requirement, verify correct
connection between batteries.

1.3 Checking AC Input Voltage
1. Set the AC output circuit breaker (in the AC power distribution box) to ON position.
Keep the AC input circuit breaker ( in the ZXDU68 G020 cabinet) in OFF position.
2. Turn the knob of the multimeter to the AC voltage scale and measure the AC voltage.
Check items: L1-N, L2-N, L3-N, N-PE
Check Criterion: 1. The N-PE voltage should be lower than 5 V. If the voltage does not meet the requirement,
it is recommended to improve AC input power supply.
2. The phase voltage should be within the range of 85 V - 295 V. If the voltage does not meet the requirement, it is recommended to start a diesel generator to power the ZXDU68
G020 system.
Check Criterion: An alarm sound given by the multimeter indicates that there is a
short circuit! Locate any short circuit and eliminate it before proceeding to the next step.
