ELECTRICAL WIRING

9-1. OVERVIEW OF POWER WIRING

9-2. WIRE DIAMETER AND MAIN POWER SWITCH CAPACITY

9-2-1. Wiring diagram for main power supply

9-2-2. Power supply wire diameter and capacity

This chapter provides an introduction to electrical wiring for the MULTI-S series, together with notes concerning power wiring,
wiring for control (transmission wires and remote controller wires), and the frequency converter.

(1) Please refer to your electric power company about the indoor wiring specifications for the power wire diameter

and capacity of protective devices (switches and leakage of breakers).

(2) Taking into consideration voltage drops caused by the length of the wires when operating devices installed

downstream, determine the specifications of wires able to handle the maximum current or voltage. In addition,
protective devices must be able to protect against current leakage or excessive current.

(3) It is generally necessary to include leakage breakers when installing wiring for the Mr. SLIM MULTI-S series.

Protective switches (excessive current protection) along main or branch lines should typically consist of fuseless
breakers (ELB).

(4) Please perform grounding.
(5) It is suggested that you consult with your electric power company concerning restrictions on electrical specifications.
