IMPORTANT! It is very important to reduce
stress from the cables on the connectors. We
recommend that all cables are fixed to the HCU
with strain reliefs.
Mount strain reliefs as shown in the illustration above.
IMPORTANT! Always make sure that the lock-
ing mechanism between the male and female
connectors closes with a click. This guarantees a
water-tight correct closure.
