Unpacking and Installation
5.1
Inspection
The 42L Series DC loads are carefully inspected before shipment. If instrument damage has
occurred during transport, please inform Adaptive Power Systems’ nearest sales and service
office or representative.
5.2
Load Module Installation and Removal in Mainframe
The 42L Series load modules must be installed in a suitable 44M0X mainframe chassis to be
used. The mainframe provides all required bias supply voltages as well as force air cooling of
the load module(s).
If ordered at the same time as a 44M0X mainframe, the load modules on the same purchase
order will be shipped already installed from the factory. If a load module requires
installation or removal in the field, the end user can perform this task easily using the steps
below.
CAUTION
The 4 Series load modules are not hot-swappable! Always turn OFF the
mains power to the 44M0X mainframe before installing or removing a load
module.
5.2.1
Module Removal
1.
First, ensure AC power to the 44M0X mainframe is switched
OFF
. Failure to do so
may result in damage to the load module. The load modules are NOT hot-
swappable.
2.
Loosen and completely remove the Phillips screw in the lower right hand corner of
the load modules front panel. This screw prevents the load module from sliding out
of its slot position.
3.
Once the screw is removed, the handle can be pulled forward to level the module
out of its back plane connectors.
4.
Once the level has been pulled as far as it will go, the module can be slid out
carefully by pulling it forward until it completely clears the mainframe front bezel.
Refer to Figure 5-3 on next page for an illustration.
