Ma Remote Controller - Mitsubishi Electric PAAA18AA1 Installation Manual

15.6.1. MA remote controller

The PAA unit control board can be controlled by an MA remote controller (non-polarized 2-wire) that is
connected to the MA-bus. Connect the white and blue wires from the remote controller to connections 1B
and 2B on the terminal block in the control box.
CAUTION
Ensure that the wiring is not pinched when fitting the control box cover. Pinching the wiring
may cut it or cause an inadvertent short circuit.
CAUTION
Install wiring so that it is not tight or under tension. Wiring under tension may break or
overheat and burn. Fix power source wiring to control box by using buffer bushing or mini-
mal tensile force. (PG connection or the like.) Connect transmission wiring to transmission
terminal block through the knockout hole of the control box using ordinary bushing.
CAUTION
Install wiring so that it does not touch the board or surrounding parts. Wiring that touches
surrounding parts may be cut by long-term operation.
Specifications are subject to change without notice.
