First, install a conduit fitting (not
contained in scope of delivery) to the
34.52 mm hole. This must be a suitable
fitting for a 1 Inch conduit with lock nut.
Inside, the clearance around the hole is
5 mm, the maximum space for the nut is
8 mm. Then, insert your wiring through
the opening and mount it to the M6 mains
terminals. Observe the correct polarity.
Close the conduit fitting to ensure water
tightness. For strain release, two M5
threaded holes are provided; the distance
between the threaded holes is 34.5 mm.
Mount the housing cover by inserting it
into the recess at the repeater cabinet
and fastening the two M3 x 12 captive
screws.
Attention: For the DC power supply connection, a minimum cross section of
6.6 mm
2
(
≤
AWG 9) per potential is required. Each wire must
observe the applicable national regulations regarding loop
impedance, voltage drop, and methods of installation. Make sure
to connect the correct voltage to the unit. To ensure water-
tightness of the unit, use the correct size of cable gland.
Note:
Do not connect or disconnect the power cord at the mains connector while
power is on. Turn off mains* power before connecting the power cord at
the Remote Unit, then, engage mains again.
* Mains power must be interruptible with an external mains breaker (40 A). For the mains breaker,
observe the local regulations of the DC provider.
