COMPLETE SYSTEM EXAMPLE
[4] Use round crimp-style terminals for connecting wires to the
power supply terminal block.
If unavailable, observe the following points when wiring.
• Do not connect wires of different gauge to the same
power supply terminal.
(Looseness in the connection may cause overheating.)
• Use the specified electric wire. Connect the wire securely
to the terminal. Lock the wire down without applying
excessive force to the terminal. (Tightening torque:
131N·cm ±10%)
[5] Tightening torque for the terminal screws.
• Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head
of the screw might be damaged, and the screw will not be
properly tightened.
• If the terminal screws are tightened too hard, screws
might be damaged.
• Refer to the table below for the tightening torque of the
terminal screws.
<Precautions when connecting the ground>
When pulling the ground wire out, wire it so that it comes
through the cut out section of the cup washer.
(An improper ground connection may prevent a good ground
from being achieved.)
10. 3 REMOTE POWER SUPPLY WIRING,
TRANSMISSION WIRING, COMPUTERISED
CONTROL WIRE
• Pass the remote control wiring, the transmission wiring,
and the computerised control wire into the control box
through the through-hole and connect to the terminals
on the X3M terminal block. After connection, secure
with the included clamping material.
(Refer to Fig. 18)
[PRECAUTIONS]
• Refer to the “Remote Controller Installation Manual” on how
to install and lay the wiring for the remote controller.
• Do not, under any circumstances, connect the power wiring
to the remote controller or transmission wiring terminal block.
Doing so can destroy the entire system.
• Connect the remote controller and transmission wiring their
respective terminal blocks.
10. 4 WIRING FOR THE HUMIDITY REGULATOR
(LOCALLY PROCURED)

<VKM-GBMV1 SERIES ONLY>
• Pass into the control box together with the power wire
through the power wiring through-hole.
• Remove the short-circuit wires (1 and 2) on the X1M
terminal block and connect the wiring for the humidity
regulator.
• Secure with clamping material together with the power
wire.
(Refer to Fig. 17)
<VKM-GBMV1 series only>
• If using humidistat, install one per Heat Reclaim Ventilator unit.
Controlling more than one Heat Reclaim Ventilator unit with a
single humidity controller may prevent normal humidity oper-
ation and cause water leakage, etc.
10. 5 WIRING EXAMPLE
• This unit can be used as part of the combined operation sys-
tem used together with indoor units (VRV system air condition-
ers), or as a independent system for processing outside air.
• When connecting with a cooling free building multi type and
bringing the RA of this unit directly in from the ceiling, con-
nect to a BS unit identical to the building multi indoor unit
(master unit), and use group-linked operation. (See the Engi-
neering Data for details.)
