4. Away from water. Protect from exposure to water, including water sprayed from
nozzles. In a wall-mounted configuration, mount the batteries at least 50 mm (2
in) off the ground.
5. Orientation. Install the battery in any direction other than face down. Do not
install face-down.
6. Indoor or outdoor. Suitable for use indoors. Refer to Section 3.3, Environmental
Specifications for temperature ranges in which the battery can operate.
• Using this product in a location that does not meet requirements will void the
warranty.
9.3 DC Cables
FIRE HAZARD
• Undersized cables can become hot and may potentially catch fire.
Failure to follow these instructions can result in minor to moderate injury.
The DC battery cables should meet the following requirements:
1. Copper-stranded cable. DC cables must be stranded, copper, and rated 90 °C
minimum. Terminate the cables with lugs that fit the DC terminals.
2. Minimum cable lengths. Select a location that minimizes the length of
battery cables to reduce voltage drop from the impedance leading to reduced
performance.
3. Appropriate cable gauge. The cables should be capable of carrying the normally
expected current, plus a margin of safety.
4. Proper polarity. Positive (+) is connected to positive (+), and negative (-) is
connected to negative (-).
5. Minimum cable lengths. Select a location that minimizes the length of
battery cables to reduce voltage drop from the impedance leading to reduced
performance.
9.4 Protection
FIRE HAZARD
• Undersized fuses and disconnects may become overloaded and potentially cause a
fire.
• Fuses and disconnects are required to open before the cable reaches its maximum
current carrying capability.
Failure to follow these instructions can result in minor to moderate injury.
Additional DC overcurrent protection and a DC disconnect switch are required to
protect the system and DC battery cables.
