All in One - Mandatory Safety Labels for Battery System
This article lists all the safety labels required by CER for STC (Battery) creation.
Before you sign-off a battery job, you may use this article to double-check the labels ensuring you have attached all the mandatory labels to the system you have installed.
"PV" & "ES" Labels on Meter Box
You must fit "PV" and "ES" Labels on the outside surface of the meter box.
Make sure the descriptive codes correctly reflect the system design and the battery's chemistries.
(a) "AC" — For inverters where the calculated PV d.c. circuit maximum voltage is less than 120 V d.c. at the inverter PV input, and the PV modules are within 1.5 m of the inverter are installed.
(b) "DP" — Where a disconnection point is used as the isolation method.
(c) "SW" — Where a load break disconnection device is used as the isolation method.
"UN3480" is UN classification code for Lithium-ion batteries, including LiFePO4 batteries.
Backup Supply Related Labels
Warning Label (Multi-mode Inverter)
Alternative Supply Circuits Label
The two labels are mandatory when you install a system with backup supply.
If your system has backup power supply - either 1) through separate backup circuits, or 2) as a whole house backup, you must clearly identify the switches of the circuits which keep live during grid outages (or when grid supply is deliberately switched off).
You must fit Warning Label (Multi-mode Inverter) to switchboard and fit Alternative Supply Circuits Label to all backup supply switches
Shutdown Procedure Label
You must fit a Shutdown Procedure Label to switchboard.
If your inverter is away from the main meter box, you should also fit one Shutdown Procedure Label onto the inverter.
Battery Warning Signs
Battery warning signs can be fitted on the wall or on the front side of the battery.
Danger, Toxic Fumes (applicable on all Lithium-ion batteries, including LiFePO4 batteries)
Danger, Risk of Battery Explosion (normally N/A on Lithium Iron Phosphate (LiFePO4) batteries)
Arc Flash Hazard
Hazardous D.C. Voltage (current and voltage must be written)
Chemical Hazard Sign (normally N/A)
