Installation - Theben TIMEGUARD LEDBHR25WPIR Installation And Operating Instructions Manual

• Reflective surfaces (i.e. pools of water, white painted walls,
overhanging branches and other types of foliage) may cause
false activation under heightened weather conditions.
• During extreme weather conditions the PIR may exhibit
unusual behaviour. Once normal weather resumes, the
PIR will carryout normal operations.

• Undo the cable gland sufficiently to allow the mains supply
cable to be pushed and fed through the back.
• Secure the supply cable into the luminaire through the hole(s)
provided ensuring that the cable gland, grommet or sealing
compound is used to maintain the IP rating of the luminaire.
• Leave enough slack to allow for wiring, retighten the cable
gland.
• Fix the luminaire using the correct screws for the wall plugs.
• Terminate the cable into the terminal block (see section 6
connection diagram) ensuring the correct polarity is observed
and that all bare conductors are sleeved.

• To set the PIR of the luminaire, follow the walk test procedure
as shown in section 8. Then reposition the lens over the unit,
taking care to ensure the gasket and PIR pin connector is in
place and that the pin connector is not hanging from the socket.
