EN
The installation and, if necessary, the maintenance and the disassembling must be
carried out by a qualified electrical installer.
The installation must be compatible with local regulations.
Check the maximum circuit length for your circuit breaker in the next table:
Maximum circuit length at 230 VAC and for 20°C start-up temperature
C-characteristic circuit breaker
Multiple units on multiple power points can be used if longer heating cables are
required. We recommend to use nVent RAYCHEM SV-SBS panels to operate 3, 6, 9 or
12 heating circuits

The nVent RAYCHEM Raystat V5 has a removable top lid. Both top and bottom of the box
have electronic parts and are connected to each other by an Ethernet connector cable.
The unit is delivered with top lid and back part dismantled.
Warning:
For over voltage protection (e.g. in case of thunderstorm) we recommend
the use of an external over voltage protection device.
Care and maintenance
Clean the Raystat V5 with a soft damp cloth only, do not use any solvents. Do not
pour water directly on the device. Do not use a water hose or a high pressure cleaner.
3.1. Description
nVent RAYCHEM Raystat V5 is an electronic control thermostat with display,
advanced alarm facilities and the capability of switching large currents (25 A). The
Raystat V5 is designed to control nVent heating cable systems. Heating cable can be
controlled (switched ON/OFF) either directly by the Raystat V5 or via a contactor.
Direct switching of heating cables is possible for heating loads up to 25 A.
For heating loads above 25 A indirect switching via a suitably rated contactor con-
trolled by a Raystat V5 is necessary.
Installation and all wiring must be in accordance with applicable regulations.
The device must be installed in non hazardous areas only. nVent offers other controls
for use in hazardous areas.
The sensor must be installed. Attention: The sensor position on pipe or in Air
needs to match the operation mode Line or PASC (ambient temperature
measurement control). A wrong assignment can led to a frozen pipe.
An alarm terminal makes remote signalling of errors possible. The unit can be
pre-programmed in power-off mode by external power bank (to be ordered separately)
connected via A-A-USB cable and USB connection.
