Table 2-8 Procedure for Power Wiring Models

Step Action

1Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.

2Locate the power terminal block for your recorder model.

•See Figure 2-9for models without CE Mark.

•See Figure 2-10for models with CE Mark.

Note that the power connection between the boards on two-pen models is made at the factory. On CE Mark and UL models the connection between the terminal block at the bottom of the case and the PCA is also made at the factory. In all models, you only have to connect power to a single terminal block.

3Run the power wires separately through the conduit hole indicated in Figure 2-7or Figure 2-8.

4Strip 1/4-inch maximum of insulation from the end of each wire and form end to fit under a screw connection.

ATTENTION: To avoid damaging the recorder, be sure that you install the power wires into the correct screw terminals as shown Figure 2-9and Figure 2-10.

5Tighten the screws to secure the wires.

6Dress the wires with as much slack as possible. Do not bundle any low level signal wires with the power wires. Refer to Table 2-6for permissible wire bundling.

Refer to Appendix A for additional information concerning noise interference prevention.

WARNING SHOCK HAZARD

Input line voltage may be present on the instrument ground plane if earth ground is not attached.

Failure to observe this precaution can result in serious personal injury.
