Figure 7: RS400 Series Power Supply Inputs
The RS400 Series power supply inputs are connected as follows:
1.
+/H
= DC (+) / AC (Hot) is connected to the positive (+) terminal if the power
source is DC or to the (Hot) terminal if the power source is AC.
2.
-/N
= DC (-) / AC (Neutral) is connected to the negative (-) terminal if the power
source is DC or to the (Neutral) terminal if the power source is AC.
3. Surge Ground
is connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all
surge and transient suppression circuitry internal to the RS400 Series.
4.
Chassis Ground
is connected to the Safety Ground terminal for AC inputs or the
equipment ground bus for DC inputs.
NOTES
:
1) 88-300VDC Equipment: A 300VDC appropriately rated circuit breaker must be
installed.
2) 100-240VAC Equipment: A 250VAC appropriately rated circuit breaker must be
installed.
3) A circuit breaker is not required for 12, 24 or 48 VDC rated equipment
4) Power input terminals have reverse polarity protection for 12, 24 & 48 VDC rated
equipment.
5) Equipment must be installed according to the applicable country wiring codes.
