Installation of Power modules

This section consists of procedures to explain how to install OMS 
870 power connections. 

Please follow the safety precautions when installing or removing 
any of the power modules.

Common safety precautions

Caution!

 

Static electricity can damage electronic equipment. While 
unpacking and handling electronic modules, wear a grounding 
wrist strap to discharge the static buildup. Grounding wrist 
straps are designed to prevent equipment damage caused by 
static electricity. Before making the necessary interconnections, 
connect the grounding wrist strap.

N O T E !

To prevent equipment damage and injury, do not reverse the 
polarity of the OMS 870 power connections.

Warning!

The plug-socket combination must be accessible at all times, 
because it serves as the main disconnecting device.

1.6.1

Install the OMS 870 – 48 VDC Power Module

Please follow “Common safety precautions” on page 1 -12 when 
installing or removing a power module.

Warning!

Before performing any of the following procedures, ensure that 
power is removed from the DC circuit.
