(2) Grounding
(a) Where possible, ground the PT-E independently.
The grounding work is class D grounding (grounding resistance 100
Ω
or less)
(b) When independent grounding is impossible, use the joint grounding method marked (2) below.
Figure 4.9 Grounding method
(c) The size of grounding wires must be 2mm2 or more.
Use wire in which green and yellow color is combined for grounding wire.
The grounding point should be as near as possible to PT-E to minimize grounding cable length.
CAUTION
Do class D or higher grounding work to earth PT-E.
In addition, do not share the grounding with other equipment.
(3) Remark
For PT-E731 series, if use resume function, operation shifts to either mode below when power failure or
voltage drop occurring.
1) [Continue mode]: Keep operating for 10 minutes.
2) [Standby mode]: Keep standby state for 30 minutes. Standby state is released when power
restoring; and operation is restarted immediately from the state right before power failure.
*Require th e battery pack PT-E73BAT(Optional) if use resume function.
