1.4.1 Installing the Panel
Except for dual-circuit 20/20 GMT panels, brackets are provided for either flush or extended EIA or WECO
mounting in a 19" or 23" rack. Dual-circuit 20/20 GMT panels must be mounted to a 23" EIA or WECO rack.

star washers provided, as shown in Fig. 6.
2. Tighten the screws to 35 in/lb. (4.29 N

m).
3. Remove the see-through cover.
4. Before connecting any conductor, use a multimeter to measure the resistance between the input NEG and
POS/RTN terminals at the rear corners of the panel. Expect 500
Ω
or more for both Side A and Side B.
