5.10 Connecting the 110/220 V ac power cable
This section provide the procedure for connecting the 110/220 V ac power cable with
the 3-conductor circular power plug to the iRU4438 iRRH power input connector.
Recommended use type SJOW 14/3 stranded portable indoor/outdoor round cable
wire rated 300 V, or equivalent.
NOTE
Power to the 110/220 V ac power supply cable should be switched off at
the breaker before connecting to the iRU4438 iRRH power input
connector.
To connect the ac power cable:
1. Plug the power cable plug into the power input receptacle labeled POWER located
on the bottom of the iRRH.
2. Secure the connection by hand tightening the coupling nut until you feel it "click"
into the locked position.
NOTE
The 110/220 V ac power connection must be waterproofed using a self-
fusing tape made for that purpose. The application of the tape will vary
by Operator, so local practice will determine how the tape is applied.
3. Waterproof the connection by wrapping the connector with self-fusing tape (refer
to
Required tools on page 3-1) according to Operator local practice.
5.11 Checking power
