2.6.4 Mounting BL-U1
To mount the BL-U1, you can use one of the following two methods:
Positions of direct mounting
Pull the brackets provided at four positions on the rear of the BL-U1, and fix them
with screws.
DIN-rail mounting
1. Hook the BL-U1 in the groove of the DIN rail from the top, and press the bottom
of the BL-U1 against the DIN rail until it clicks.
2. Make sure that the DIN-rail mounting hook is set in condition “A”. If it is not,
push it inward.
3. To remove the BL-U1 from the DIN rail, pull the hook so that it is set in condition
“B”.
4. To mount the unit on the DIN rail again, restore the hook to condition “A”.
