Wiring
Power requirement
External power supplied to the MX521B must be within 10.5-32 V
DC. Negative grounding is required. The MX521B draws less than
300 mA at 12 V DC. An in-line fuse or circuit breaker rated at 2 A is
recommended for overload protection.
The red wire connects to the (+) DC power, while the black wire is
the negative return. Although the antenna has a reverse polarity
protection, it is prudent to make sure that proper polarity is
observed before making the connection.
