Daikin Altherma - Low Temperature Split
4P313776-1 – 2012.05
7 Installation
1
Connect the backup heater power supply.
For *3V models, use a single pole fuse for F1B. For *9W models,
use a double pole fuse for F1B.
Special remark for fuses:
Special remark for terminals:
As mentioned on the table above, the connections on the terminals
X6M and X7M need to be changed to configure a backup heater.
Refer to the illustration below as a caution about handling the
terminals.
2
Fix the cable with cable ties to the cable tie mountings.
3
Configure the user interface for the respective power supply.
See Quick wizard: Standard.
During connection of the backup heater, miswiring is possible. To
detect possible miswiring, it is highly recommended to measure the
resistance value of the heater elements. Depending on the different
backup heater types, following resistance values (see table below)
should be measured. ALWAYS measure the resistance on the
contactor clamps K1M, K2M, and K5M.

Equipment complying with EN/IEC 61000-3-12
(European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and
≤
75 A per phase.).
(b)
This equipment complies with EN/IEC 61000-3-11
(European/International Technical Standard setting the limits for
voltage changes, voltage fluctuations and flicker in public low-voltage
supply systems for equipment with rated current

at the
interface point between the user's supply and the public system. It is
the responsibility of the installer or user of the equipment to ensure,
by consultation with the distribution network operator if necessary,
that the equipment is connected only to a supply with a system
impedance Z
