Power Supply Modules
14 Bruker
BSMS/2 Mainframe Version 001
Installation 3.2
To install the power supply modules please follow the guide below, making sure to do
each step in the order given.
Make sure that the mains cable is disconnected !
1. Check that the primary voltage selection switch is in the optimal position (see
the sticker on the back side of the power supply module):
To avoid excessive power dissipation in the power modules, the
primary voltage can be adapted by the primary voltage selection
switch (shown in Figure 7). Use a coin or a screwdriver to access
the switch. Generally, the primary voltage selection switch should
be set to the matching range; however, if the mains power is weak,
the next lower range should be chosen despite the greater power
dissipation in the power supply modules.
For Example:
230 V stable mains power ⇒ 220-245VAC position.
230 V unstable mains power ⇒ 210-230VAC position.
