To check if your PSU is eligible for replacement, first unplug the product or switch off its power.
 On the front of the PSU, you will see a four-digit production code, formatted YYWW. “YY” refers to the year and “WW” refers to the week number. Next to this code, you’ll see a part number and voltage range.
 The following combinations are affected by this replacement program:
  Description   |  Sold with   |  Voltage   |  Part number   |  Production code   |  
40 W PSU   |  Base pack or separately   |  220 V–240 V   |  S040WN2400167   |  2038 and lower   |  
40 W PSU   |  Base pack or separately   |  100 V–120 V   |  S040VN2400167   |  2037 and below   |  
40 W PSU   |  5 m outdoor lightstrip   |  220 V–240 V   |  E040FP2400167   |  2051 and below   |  
40 W PSU   |  5 m outdoor lightstrip   |  100 V–120 V   |  S040VN2400167   |  2044 and below   |  
20 W PSU   |  2 m outdoor lightstrip   |  220 V–240 V   |  S024BI2400083   |  2143 and below   |  
20 W PSU   |  2 m outdoor lightstrip   |  100 V–120 V   |  S024BI2400083   |  2146 and below   |  
  
 Example:
 You purchased a Calla bollard, which included a 40 W PSU. The PSU, which is 220V-240V, has the part number "S040WN2400167.” Your PSU may be affected. To confirm, the first two digits (i.e. the year) are below 20 or both of the following are true:
  - The first two digits of the code is 20
  - The last two digits of the code are 38 or below
  
 So, in this example, the PSU with the part number S040WN2400167 may have different production codes.
 The PSU with a 2038 production code is affected.
 The PSU with a 2111 production code is not affected.
