Technical data

To install the power supply unit (PSU), follow these steps:
1. Select a secure installation location for the PSU. Ideally, this is a location where the device
cannot be interfered with either intentionally or accidentally.
Bosch recommends using an environmentally suitable, lockable equipment cabinet.
2. Locate the four (4) mounting holes of the power supply enclosure.
3. Drill four (4) holes in the mounting surface for the mounting anchors appropriate for M6
screws (not supplied).
4. Loosen the four (4) captive Phillips head screws on the top of the lid of the power supply
enclosure. Lift the lid and set it upside down next to the enclosure.
Notice!
Do not stretch or cut, or otherwise disturb, the earth core cable (shown in the figure below)
to the inside of the lid and to the earth termination post.

5. Secure the enclosure to the mounting surface using four (4) M6 stainless steel screws and
washers (not supplied), which fit through the large holes in the enclosure.
Notice!
If you are securing the power supply enclosure in a vertical position (for example, on a wall),
one person should hold the enclosure lid while another secures the enclosure body in place,
to avoid damage to any part of the enclosure, and/or injury to the installer(s).
6. Unscrew the two (2) M3 screws on the internal high voltage input head-end shield (marked
with "Danger") covering the mains cable terminal HD1; retain the screws.
