3.5 Utility power
Utility can provide power to critical components on the generator set, like
battery charger, water heater, oil heater and other devices.
The battery naturally discharges while it is stored or not running. To maintain
the generator set in a good capability of starting, recharge it once a month in
summer, and every 2 months in winter. The user can charge the battery
through ATS equipment, or by connecting utility wirings to terminals of the
battery charger.
The engine will be hard to start in the cold environment. It is recommended to
equip appropriate heater unit. Connect wirings of the heater to utility before
starting the engine.
Turn on the utility switch, the heater unit starts to work. When the temperature
reaches the preset value or the engine has started, the heater unit will stop
working automatically.
3.6 Load connections
3.6.1 Select load cable
Select the cable with proper diameter, based on its allowable amperage and
the distance between the generator set and the load.
Recommend to select the proper diameter and length of cable. There is
maximum 5% marginal drop only for the rated voltage between the terminals of
loads generator set via the cable. It should be considered while selecting the
cable.
WARNING
1) If load exceeds allowable amperage, the cable may be damaged in
overheating.
2) If the cable is either too long or too small, there will be greater voltage
drop between cables which bring voltage drop to loads. It may result in
reduced performance in the connected loads.
