5.6.2 Connecting DC Power
The base station is designed to accept a nominal 13.8V DC, with negative
ground.
Notice
Any mains power supply used to power the base station is
required to meet the isolation separation for reinforced insulation of
3000Vrms or 4242VDC.
The DC power connector at the rear of the base station is a heavy-duty M4
screw terminal connector suitable for many forms of connection.
You must connect the DC supply from the battery to the base station via a
readily accessible disconnect device such as a fuse or DC-rated circuit
breaker with the appropriate rating, as shown in the table below.
The DC input leads should be of a suitable gauge to ensure less than 0.2V
drop at maximum load over the required length of lead. Use only flexible
copper cables.
Terminate the DC input leads with a suitable crimp connector for attaching
to the M4 screws of the DC power connector.
