1.6.1 Assembling the Netra 1280 Power Connectors
Note –
The following procedure is intended as a guide only and should only be
performed by a qualified electrician.
1. Turn the power switch to the Standby position.
Caution –
The On/Standby power switch does not isolate the equipment. The
circuit breakers are the primary means of disconnection for this product.
2. Remove the plastic covers from the DC inlet box (
FIGURE 1-24
).
Each cover is retained by a Phillips no. 2 screw.
3. Assemble the earth connection.

The shipping kit contains lugs for crimping customer-supplied cables. Use a
crimping tool or approved equivalent to secure the lugs onto the cables.
b. Use two M5 nuts and washers to fit the lug to the location between the two
plastic covers using the M5 nut spinner provided.
4. Assemble the power cable ends.
a. Crimp the single-hole lugs onto the input and return cables.
b. Slide the lugs through the plastic cover.
