Field wiring connection
337 1) Wiring of power supply and earthing
347 The chiller has MCB.
348 Please connect power supply wire to the terminal block.
350 And also connect wire between chiller control panel and
351 earth at field.
352 Earthing resistance : Local regulation
353 Earthing cable : Annealed copper wire
354 (Please use the wire as same the thickness as the wire
355 of the power supply)

1) Be sure to connect operation signals of the
359 chilled water pump and the cooling water pump
360 on the absorption chiller's control panel.
361 Otherwise a freeze accident may happen.
362 2) Should be work the electric wiring connection by
363 license holder.
368 3) Use steel conduit for electric wiring between field
369 electric supply and control panel of the chiller.
370 4) Field wiring connections are all low voltage
371 without supply voltage.
