5 Cabinet installation
The required distance for UPS units next to each other is 10 mm, but for maintenance and service
purposes, it is recommended to leave 100 mm space on both sides of the unit when possible. The
same applies to the optional battery cabinets that should be installed next to the UPS cabinet.
Figure 5-1: Marine UPS unit with internal input transformer
The UPS family has several alternative battery cabinets and configurations depending on the selected
back-up time and quality of batteries.
5.1 Maintenance bypass switch
UPS models with an integrated input transformer are supplied with an internal maintenance bypass
switch (MBS). The MBS may also be ordered as an integrated MBS mounted on the back of the UPS,
or as a separate MBS for wall mounting near the UPS. The internal MBS and the rear-mounted MBS
are factory installed.
