The relay switches the incoming power to the SEL-Bus PSU. Size it for voltage and load: 100A per PSU in a 12V installation, 50A per PSU at 24V.

Relay Voltage (V) Current (A) Power consumption (W)
532-498 12 100 6
532-499 24 100 6
532-599 12/24 250 3 (45 on start up)

With Protective Guard (recommended)

  1. Choose fasteners with a head smaller than Ø 9.5x4mm and thread smaller than Ø5mm (e.g. MLC6S M5, MRT M5).
  2. Drill the mounting holes.
  3. Attach the button to the guard.
  4. Connect the cables.
  5. Apply sealant in the grooves under the guard.
  6. Fasten button and guard.

Without Guard

  1. Max. mounting surface thickness 4mm; if thicker, make a 40mm countersink on the back.
  2. Drill the mounting hole.
  3. Fit the button with its nut.
  4. Connect the cables. On an uneven surface extra sealant may be needed.

Mount the button within easy reach whenever SEL-Bus devices are in use.
