DC Power Connection (if equipped) 
Using the proper power connections is vital to the safe operation of the D9887B 
receiver. The D9887B receiver is intended for use in 40-65 VDC systems. The power 
supply will automatically detect the system it is connected to. When installing the 
D9887B receiver, the power supply MUST be used in conjunction with an over-
current protective device rated at 50 V, 5 A, type: Slow-blo, as part of battery-
supply circuit. 
WARNING: 
Failure to include an over-current protective device could cause damage to the 
D9887B receiver, personnel, or property.
