FIGURE 3-7 SURGE PROTECTION
Battery connections
The cables are brought out through the top of the unit.
This cable must be sized accordingly to carry the battery short circuit current for the time required to clear the battery protection
devices.
Note:
Ensure the battery circuit breakers are open before connecting the batteries. Connect the switched cable connections first,
followed by the common return cable connections.
3.5 TEMPERATURE SENSORS
The optional sensors for measuring ambient and battery temperature are the same device (Part No. 385-5941-03, -06, -15, -30). The
system auto-detects if the sensor is plugged into one of the positions (4) or (5). If no sensor is installed, the Controller will show “Not
Available” in the menu items for the temperature measurements. Locate the ambient sensor on a mass with a fairly long thermal time
constant. (see Section 2.9) Locate the battery sensor on a battery block in the middle module of the battery bank (likely hot zone).
